20 Animals With The Longest Life Spans

By Susan Dorling | 2021 Guide

Animals in the wild today, rarely live to their prime due to high infant mortality rates, poaching, climate change and habitat loss. They fare far better is sanctuaries or wild reserve parks, places where they are taken care of.

Most of us out live our pets and its hard to imagine animals that live longer than us. Its comes as a shock to most people that some fish can live up to be a century old. In this article i have added 20 animals with the longest life spans.

1. Jellyfish

  • Lifespan: Immortal
  • Habitat: Oceans

Jellyfish are underwater creatures that have been around for millions of years, and jelly-like creatures can be found both in warm water as well as cold water bodies. Jellyfish come in all sizes and colors, such as pink, blue, purple, and yellow. These creatures are invertebrates, and they are known to be self-illuminating.

An important face about Jellyfish is that some of them are thought to be immortal. The life of a jellyfish is divided into two phases, the stationary phase, and the mobile medusa phase. There are many kinds of Jellyfish out there that travel backward to the polyp stage when they get stressed.

A group of fish is known as a school, and just like that, a group of Jellyfish is known as a smack or, better yet, a swarm. Jellyfish actually have the ability to clone themselves; if you cut a jellyfish in half, it can regenerate from the pieces and create two organisms. Just like that, if a jellyfish is injured, it can heal itself and potentially go-ahead to produce hundreds of offsprings.

Jellyfish, unlike most organisms, have no eyes, bones, and no brain. They are made up of bags like smooth bodies and tentacles armed with stinging, tiny cells. They use these deadly tentacles to sting prey and trap them before gobbling them up. This may seem disgusting to most people, but Jellyfish use the same opening to eat and discrete waste. Their mouths can be found at the center of their body.

Jellyfish prey on shrimp, fish, crabs, and tiny plants. They have to eat and digest very quickly as the weight of the undigested food can restrict their ability to float easily.

2. Ocean Quahog Clam

  • Habitat: North Atlantic Ocean
  • Lifespan: 507 Years

The Ocean Quahog is a species of clam that is safe for human consumption and is a marine bivalve mollusk in the family Arctiidae. This species can be found in the North Atlantic ocean, as it is harvested as a food source on a commercial level.

This species of clam is also known as mahogany quahog, Icelandic cyprine, mahogany clam, black clam, and black quahog. The Ocean Quahog is a very deep water clam with the mahogany brown colored shell. This species became the Official Shell of Rhode Island in the year 1987.

The Ocean Quahog Clam is known for its long lifespan, and one specimen known as Ming was estimated to live up to 507 years in the wild. A study showcased that in animals aged 4 to about 192 years, the decline of antioxidant enzymes was rapid in the first quarter of a century, which includes the sexual maturity and growth period, but afterward, it tends to remain stable for over 150 years. Plus, the proteins damaged by oxidation in the heart of the organism do not change significantly up to 120 years of age.

The ocean quahog clam has pretty high proteome stability, specifically when compared to short-lived mammals. Ocean Quahog clams grow to about 50 mm or to inches in shell height. Ocean quahogs are bivalve mollusks, which mean they have shells with two hinges that enclose their body. They have oval-shaped, thick shells, and they have a while interior with a purple border.

These beauties spawn by releasing eggs and sperm in the water column where the eggs are supposed to be fertilized. Their larvae are carried around by the current for at least 30 days until they develop into juveniles, after which they sink to the bottom.

3. Greenland Shark

  • Habitat: Atlantic Ocean
  • Lifespan: 260 Years

The Greenland Shark is also known as the gray shark, the gurry shark, sleeper shark, or by the Inuit name Eqalussuaq. It is actually the second-largest shark after the Great White, but there is really no reason to panic as is this species of shark lives in the deep waters of the Atlantic Ocean where it rarely encounters people. These sharks are famous for their extremely long lifespans: more than two centuries on average. These beauties are thought to be one of the longest living vertebrates on Earth.

The Greenland shark has a cylindrical body, a sluggish look, and a small head with a tiny eye and a short snout. This species is actually one of the unique sharks out there, both in appearance and behavior. These sharks tend to move very slowly and are considered as one of the slowest swimming sharks in the world.

These magnificent creatures are not as common as one might think. The first underwater photos of the Greenland Shark were taken in the year 1995 in the Arctic. And the first video was not captured until the year 2003.

This species of shark is native to the North Atlantic waters around Canada, Greenland, and Iceland. They are the only kinds of shark that can bare the drastic Arctic temperature and are the only true sub-Arctic shark. They prefer to live in extremely cold waters, and in the summer, they tend to live at the bottom of the ocean, where the water is the coldest. As winter comes, these sharks vertically migrate to the surface layer, which at that specific time is much colder as compared to the water at the bottom of the ocean.

4. Lamellibrachia Luymesi

PC: Wikipedia.com
  • Habitat: Gulf of Mexico Basin
  • Lifespan: 250 Years

Lamellibrachia Luymesi is a large worm that is found in the Atlantic Ocean, specifically in the northern part of the Gulf of Mexico. This area of the Gulf of Mexico basin contains a number of hydrocarbon cold seep vents. These specific cold seep vents are powered by the tectonics of sediment and a compact salt layer, which is located beneath the Gulf of Mexico basin. This species of worm is known for its long lifespan; they can live up to 250 years on average.

These sedentary worms are most abundant along the Louisiana slope of the Gulf of Mexico basin. However, they were first discovered in the late 1970s along the Guyana Shelf. These species of arms live within a secreted tube. Their curling or wavy tubes are off white in color, and their plumes are deep red in color. They do not possess a gut or a mouth because they depend on chemosynthetic bacterial endosymbionts for nutrition.

Mature seep worms have a tapered, thin body plan. This species of worm can reach as high as 1.5m above the seafloor, and it grows about 1cm per year.

Lamellibrachia Luymesi provides the bacteria with oxygen and hydrogen sulfide by absorbing them from the places around them and binding them to a specialized hemoglobin molecule. These worms use their roots, which are the posterior extensions of their body to absorb hydrogen sulfide from the seep sediments. The symbionts of the worm them oxidize the sulfide in order to produce energy for carbon fixation and release hydrogen ions and sulfate as by-products. It is important for the worm to excrete these waste ions; it could do this by using its roots or across its vascular plume.

4. Red Sea Urchin

  • Habitat: California Bay
  • Lifespan: 200 Years

Red Sea Urchins can be found in the rocky subtidal habitats in regions just below the low tide line, where the wave action is not that drastic to about 300 feet. They are abundant in warm water and tend to avoid locations with muddy or sandy sediments. Red Sea Urchins can live up to be about 200 years old. This time frame does vary from species to species.

The body of the red sea urchin is flat from below and domed from above. The external skeleton of the red sea urchin is known as the test, and it is made up of 10 chalky plates that are fused together and covered with spines. Every other section has several holes in it through which the tube feet of the urchin has been extended. These feet are flexible, long tentacles that end in tiny suction cups.

The spines of the red sea urchin are connected to the test via ball joints that allow them to point in every direction. Also present among the spines and close to the mouth is pedicellaria, which is pincer-like structures. The color of the sea urchin varies between dark burgundy and uniform red.

Red sea urchins are larger than any other urchin species, and in California, the maximum test diameter ever calculated was about 127 mm and spine length 2 to 3 inches. In British Columbia, the red sea urchins can grow to a diameter of about 180 cm with spines about 8cm long. The annual growth rate in adult sea urchins is slow, which is less than 0.004 inches, experts believe that they never stop growing, no matter how old they get.

5. Bow Head Whale

PC: Thecanadianencyclopedia.com
  • Habitat: Near Arctic
  • Lifespan: 100 to 200 Years

Bow Headed Whales are names after their bow-shaped head and can be found in the Arctic during July, they are actually the most sought after species for whale watching in the Arctic.

This species of whale has a large appetite and can devour about 2 tonnes of food on a daily basis. In a year, Bowhead whales eat up to 100 tonnes of food; they feed by swimming with their mouths open. They filter through their food using keratin bristles, baleen plates equipped to sift out water, and capture zooplankton to feed off of. They mostly feed during the summer month in the Canadian Arctic.

Bowhead whales are actually one of the longest living species in the world and can live from 100 to 200 years on average. These whales use their bow-shaped head to break through the ice, and their skull makes up 1/3rd of their total length.

These beauties are humongous; they are thought to be one of the largest whale species in the world and can weigh up to 100 tonnes. On average, the length of a bowhead whale is 15 to 18 m, but experts have witnessed some as long as 20m.

These whales are known for their intense social group interactions. These interactions consist of flipper slapping, tail slapping, and breaching. Don’t let their massive size fool you; bowhead whales can breach entirely out of water.

One of the most interesting facts about these whales is that they possess the thickest coating of blubber of any sea mammal, layers being 19 inches thick. Blubber helps to maintain the body temperature of the whales, so they remain insulated throughout all of the Arctic seasons.

6. Galápagos Tortoises

PC: Wikipedia.com
  • Habitat: Galapagos Islands
  • Lifespan: 100 Years

The Galapagos Tortoise is a beautiful sight, scaly, tall, and nearly prehistoric; it sure does know how to make an entrance. These are among the largest species of tortoises in the world and among the longest-lived. They can live up to be about a century on average; the oldest recorded Galapagos Tortoise was about 170 years old.

As obvious from their name, these tortoises can be found on the Galapagos Islands, off the coast of Ecuador. Galapagos comes from the Spanish world Galapagos which the original explorers used to mean saddle because of the shape of the tortoise’s shells. When these animals were first discovered, people actually used to ride them, but not this is illegal, as it is quite harmful to the turtles.

Unlike cartoon tortoise, you cannot really remove a tortoise’s shell. Their shell is a part of their body, it is an integral part of their skeleton, and when the tortoise gets scared or feels threatened, it can pull its head as well as its legs inside the shell.

The Galapagos tortoise that lives in the colder regions have a dome-shaped shell that restricts neck movement; hence, they feed on grass. The tortoise that can be found in warmer climates has a saddle-shaped shell, which allows them to stretch their necks in order to grab vegetation that grows above the ground, such as leaves, fruit, and vines.

This species of tortoise is quite different than other tortoise as unlike many animals; these beauties can survive a year without food and water. They are also slow-moving creatures that can travel long distances at a speed of about 0.18 miles per hour.

7. Rougheye Rockfish

PC: Schooloffish.com
  • Habitat: Pacific Ocean
  • Lifespan: 100 to 200 Years

The Rougheye rockfish can be found in depths between 170 and 660 m. They typically live near the seafloor around the crevices, caves, and steeply sloped boulder fields that are surrounded by soft terrain.

Their diet consists majorly of shrimp, but they are also known to feed on crabs, other fish, and tiny crustaceans. The females spawn by releasing their larvae from ovaries filled with eggs mostly between the month of February and June. This species of fish matures rather late in life and grows super slowly. They are actually one of the longest living marine fish species present on Earth; they can live up to 200 years.

This fish species has a bright pink or red body with gray or black patches. The pectoral fins are generally marked with black ends, giving it the nickname blacktip rockfish. The fillets of the fish are bright white. The posterior part of the lateral line is often pink.

The blacktip rockfish grows to a maximum height of about 97 cm in length, with its weight being around 6.7 kg on average. These magnificent creatures live in the forms of schools sometimes, but most of the year, larger fish are solitary or roam around in small groups.

It can be rather difficult to distinguish between Rougheye rockfish from a number of other fish species, especially the Shortraker rockfish, which is a close cousin. There are more than 70 species of rockfish in the eastern Pacific. These fish are actually named after their distinguishing feature: spines along the lower rim of their eyes.

8. Pacific Geoduck

  • Habitat: Pacific Ocean
  • Lifespan: 150 Years

A Pacific Geoduck is actually the largest burrowing clam in the world, and it occasionally reaches about 10-pound sin weight with a shell of about 8 to 10 inches long. It is also one of the longest living animals in the world; it can live up to 150 years of age.

The Geoduck is not related to ducks in any way; the name was coined by a Native American tribe that lives in western Washington, who called it gweduc, which means dig deep and referring to the bivalve burrows way below the seafloor. The Europeans later altered the spelling as well as the pronunciation.

The Geoduck has two main parts, the neck or siphon, which hangs out of the shell and the mantle, which is also called the breast; it is the meaty part that is present inside the shell. These living organisms anchor themselves into the ground using a small foot, and then they remain in the same position for the rest of their lives.

Below the ground, the clam sucks in seawater and filters for precious vitamins and plankton and then squirts out the rest using its siphon. The length of the siphon can easily stretch from a banana into a baseball length; it really depends on how comfortably situated the clam is. These clams take about a decade to completely mature.

The clam is far too big to retrieve into its shell-like other mollusks; instead, the neck just hangs outside in all its glory. These beauties can be found along the West Coast from Alaska to Baja California, and they are very abundant in British Columbia and Puget Sound.

9. Japanese Spider Crab

  • Habitat: Surrounding waters of Japan
  • Lifespan: 100 Years

The Japanese spider crab is the only member of the genus Macrocheira and is a species of marine crab. The crab can only be found in waters that surround Japan. The creature has the largest leg span of any arthropod on Earth, reaching up to 12 feet and weighing 19 kg. It is considered a delicacy and is subject to fishing.

The Japanese Spider Crab actually has the longest lifespan of any crab and can live up to be a 100 years old; however, they do not fare so well if they get injured. The crab can be found on the Pacific side of the Japanese Islands, Kyushu and Konshu. They are found usually in Suruga, Sagami, and Tosa bays. As well as off the coast of the Kii peninsula. This great species of crab was also once found as far as Su-ao, in eastern Taiwan. This was just a rare event, as it is possible that extreme weather or a fish trawler may have carried the crab much further south than its usual home range. The Japanese spider crab can survive up to the depths of 750 meters.

This species of crab is actually a scavenger, which means that it usually feats on animals that are dead, but it does sometimes also feed on shellfish, opening the shells by making use of its giant claws to feast on them.

After molting, the Japanese spider crabs are known to eat their own shells to get some vital nutrients. Mating among Japanese spider crabs takes place with the ventral surfaces of the two partners opposing each other, and it happens as soon as the female crab completes her molt. Fertilization is internal; the abdomen of the female is far wider than that of the male, which provides space for the brooding of the egg mass. The fertilized eggs are then laid shortly after mating.

10. Condor Vulture

  • Habitat: South America
  • Lifespan: 60 to 90 Years

The Andean Condor Vulture is native to South America, and it belongs to the New World vulture family Cathartidae, it is also the only living ember if the genus Vulture. This species of vulture is actually the national symbol of Colombia, despite its dwindling numbers. Even though the vulture is a beautiful, majestic bird of enormous size, not many people are aware of its existence.

The Condor Vulture actually has one of the longest lifespans in the world and is considered one of the longest living birds. They are known to live up to 60 years, which is shocking when it comes to birds.

The Andrean Condor is the largest of all vulture species; it has a wingspan that spreads across about 3.5 meters, which is the biggest of any bird. The vulture can weigh up to 15 kilograms, and it uses thermal air currents and air currents to help keep its body afloat during flight.

Even though condor vultures are an amazing wingspan, they sometimes are a hard time staying afloat during the flight due to their heavy body. This is why this species of bird prefers windy areas, where it can glide effortlessly. It helped by Mother Nature; the beauties can soar up to a breath-taking height of 5,500 meters!

These birds have a very distinct appearance; they have velvety sleek looking black feathers that cover almost all of their body, and unique white flight feathers that reach out like fingers in the air. Both female and male vultures have a bald head, but males have a much larger one as compared to females and have yellow eyes plus a striking white ruff at the base of their necks.

11. Killer Whale (Orca)

  • Habitat: All Oceans
  • Lifespan: 80 Years

Killer whales who are more popularly known as Orcas are one of the largest marine mammals in the world, which is part of the dolphin family. Despite their name, these beauties are not actually whales. They got their name due to their sustainability as predators and their immense size. Some believe that their name was given to them by sailors who called them whale killers, as they are known to attack whales.

These magnificent creatures have a big frame, with unique black and white coloring. They have a grey patch right behind their dorsal fins, which is called a saddle. Killer whales have an impressive lifespan; they can live up to 80 years in the wild.

Orcas are generalist eaters; they feed on sea lions, fish, seals, sharks, rays, dolphins, seabirds, cephalopods, large whales, and much more. However, some orcas are picky eaters, and they feed on specific prey. Once the killer whale learns what its family eats, it will most probably not switch its diet.

As compared to humans, Orca’s sleep is a rather different way. When we lose consciousness or sleep, we still keep on breathing, but unfortunately, orcas cannot do that. They need to stay conscious, even when they are sleeping, as their breathing is no automatic like us. The creatures have to decide what they want to breathe actively, so they must be aware even when they are deep in slumber. If Orcas go to sleep like us, they will most probably suffocate, stop breathing and sink to the bottom.

Just like humans, in Orcas, knowledge is transferred from the elders to the young ones, what to eat, where to hunt, how to hunt, who to avoid, the distinct accent of the population, and calls unique to family groups and pods.

12. Indian Elephant

  • Habitat: India
  • Lifespan: 80 Years

There are different kinds of elephant species in the world. They can be divided into two major branches, the African elephant and the Asian Elephant. The Asian Elephant can further be divided into different categories, among which is the Indian elephant.

Indian elephants can weight about 5 tonnes and can grow up to be 6’11 feet tall. They are majestic animals that are not just stunning to look at but also incredibly smart. Indian Elephants can live up to be about 48 years of age, and some are even known to live as much as 80 years. Indian elephants are both nocturnal and diurnal. T

These beauties are highly social animals and gather into matriarchal units. These small groups may consist of 20 related females, being led by the oldest female. The leader guides the group in their search for water and food sources. These herds sometimes divide into smaller, temporary groups, and then they communicate with other small groups by low-frequency vocalizations.

The trunk is the best feature of the Indian elephant, and it is an amazing system of muscles. The Indian Elephants use their trunk to pick up food and move it to their mouths. These beautiful creatures are herbivores, which means that they only consume plants; their diet consists of stems, grass, bark, and leaves. As elephants are huge, they eat and poop a lot, and all this eating and defecating are great for the environment and the land.

Indian Elephants have huge tusks that help to protect their trunk and can also be used to dig holes. Unlike their African counterparts, both the sexes do not have tusks; only male Indian Elephants have tusks.

13. Koi

  • Habitat: Japan
  • Lifespan: 40 to 60 Years

Koi fish are actually freshwater fish that were originally brought to Japan as a food source. They are the descendants of the hardy Carp, and they have excellent adaptively skills; that’s why they can be found all over the world. People in Japan believe that koi fish symbolizes love, prosperity, wealth, good fortune, and a successful career. Each variety of koi is associated with one of those values.

Koi fish can live up to 40 to 60 years, but they only reach this staggering number in the wild. The longest living koi lived up to be 226 years of age and died in 1977.

Koi can be found in a variety of different colors, not just the typical orange. The color of the fish actually depends on the variety. They can be cream, red, yellow, black, white, and blue in color. The beauties can also be covered in spots of different sizes. The different hues of colors have developed their own connotations. A blue koi is thought to bring serenity, the gold koi symbolizes wealth and prosperity, the metallic koi is said to bring success in business, and the red, grey, and blue symbolize positivity.

Koi fish are super smart, and they have the ability to recognize the person that feeds them. They can also be trained like a cat or dog, to eat from his or her hand. This species of fish is omnivorous and is known to eat pond plants as well as different kinds of eggs, fish, watermelon, lettuce, and peas. Koi can easily grow up to about three feet long, provided they are kept in optimum conditions, and they are given what they need in order to stay well and healthy.

14. Human Female

  • Lifespan: 72 Years

A female human being is known as a woman. The word woman is actually reserved for the adult female, while younger females are known as girls or female children. Typically a female human being has two chromosomes and is capable of producing offsprings from puberty until menopause. A human female can live up to 72 years of age on average.

The female anatomy is quite similar to male autonomy; the only major difference is the reproductive system. The female human being has ovaries, fallopian tubes, vulva, breasts, Skene’s glands, and Bartholin’s glands. The pelvis of a female is much wider than that of a make; the hips are typically broader.

Women have significantly less body and facial hair as compared to their male counterparts. On average, a female human being is much shorter and leaner than men.

Throughout human history, women have been given a secondary role and were more or less labeled as homemakers, caretakers, mothers, and wives. Traditional gender roles limit the activities as well as opportunities for women.

The female human being is also subject to more violence as compared to males; this is because they are considered the weaker sex and are subjected using religion, law, and family. Some women are even denied the right to make decisions about their own bodies, and they have restricted reproductive rights.

In terms of biology, the sex organs of a female are a part of the reproductive system, while the secondary characteristics are involved in attracting a mate and breastfeeding children. The ovaries of the females produce eggs, which are known as gametes, and those are then fertilized by the sperm of the male, in order to form new genetic individuals.

15. Human Male

  • Lifespan: 70 Years

A human male who is also known as a man like most other male mammals generally inherits a Y chromosome from his father and an X chromosome from his mother. The male fetus produces small amounts of oestrogen and larger amounts of androgens as compared to a female fetus. The significant difference in the amounts of these sex steroids are largely responsible for the differences in the physique that distinguish between women and men. The lifespan of a male is less as compared to that of a female; they live up to 70 years on average.

During puberty, hormones stimulate androgen production, and that leads to the development of secondary sexual characteristics in man, thus further dividing the gap between man and female human bodies. However, there are exceptions to the above for some intersex and transgender men.

All humans showcase sexual dimorphism in many characteristics, many of which do not really have any link with their reproductive ability, although most of these qualities do have a major role in sexual attraction. Most expressions of sexual dimorphism among male humans can be found in weight, height, and body structure.

Secondary sexual characteristics in male human beings include:

  • Facial hair
  • Broadened Shoulders
  • Chest Hair
  • An enlarged Larynx
  • A voice that is deeper than that of a female or child

The reproductive system of a male includes both internal as well as external genitalia. The external genitalia of the male includes the male urethra, the penis, and the scrotum. The internal male genitalia, on the other hand, consist of the prostate, the testes, the seminal vesicle, the ejaculatory duct, the vas deferens, and the bulbourethral gland. The function of the male reproductive system is to produce semen, which carries sperm and genetic information that can bind with the egg of the female human being.

16. Tutara Lizard

  • Habitat: New Zealand
  • Lifespan: 70 to 100 Years

The Tuatara is a reptile that is lizard-like and belongs to the group of beak headed reptiles. All the members of this group, apart from two different species of Tuatara, went extinct about 60 million years ago. These lizards are native to New Zealand and were found in numerous numbers until the introduction of the Polynesian rats that feed on Tuatara eggs.

Tuatara Lizards can survive more than a century in the wild, and they reach sexual maturity at the age of 15 to 20 years, but the shocking thing is that they can still produce at the old age of a 100. Their longevity is associated with their slow metabolism. These reptiles can also tolerate much cooler temperatures than most reptiles, and they also hibernate during the winter months.

The Tuatara have spiny crests along their backs that are made up of soft, triangular folds of the skin. These spines much more prominent in males as compared to females, and the males can even raise them during mating or territorial displays. Tuatara actually comes from the Maori word for peaks on the back.

Today these lizards can only be found on the shrubby and forested coastal areas of the 32 islands around New Zealand. The number of these species of reptiles in the wild is still high, but still, they have considered a vulnerable species due to climate changes and habitat loss.

The most interesting thing about Tuataras is that they have a third eye on their head, which is called the parietal eye. This eye has a cornea, retina, lens as well as nerve endings, but it is not used for vision. The third eye is only prominent in hatchlings, and then it gets covered in pigments and scaled after four to six months. The function of this eye is still a matter of debate.

17. Rhinoceros

  • Habitat: African and Asian Savannahs
  • Lifespan: 45 to 50 Years

They are large mammals that feed on grass and shrubs, and they are easily identified by their unique horned snouts. The word Rhinoceros actually has Greek origins; rhino means nose while ceros means horn. There are about five species of rhinos and 11 sub-species, some have two horns while others have one.

Different species of rhinos have different lifespans:

  • Indian Rhinoceros 35 – 45 years
  • White Rhinoceros 40 – 50 years
  • Black Rhinoceros 35 – 50 years

The horns of Rhinos are used in folk medicine, and so the majestic beasts have been hunted nearly to extinction. The horns are even sometimes sold as decorations or trophies, but more often than not, the horns are ground and used in traditional Chinese medication.

Rhinoceros are herbivores, which means they only feed on vegetation. The kind of vegetation they eat depends on the species. This is because the snouts of different species are different to accommodate various types of foods. The black rhinos eat bushes or trees because they have long lips that allow it to pick fruits and leaves from up high. The white rhino, on the other hand, has a flat-shaped snout that allows it to get close to the ground in order to eat grass.

A female rhino will produce after every two to five years, and they carry their young for a gestation period of 15 o 16 months. The females usually have one baby at a time, though some sometimes do have twins. At birth, baby rhinos, also known as calves, are rather large, and they can weight anywhere from 88 to 140 lbs.

A fun fact:

Compared to their large body size, rhinoceros have pretty small brains.

18. Naked Mole Rat

  • Habitat: Africa
  • Lifespan: 31 Years

Naked Mole Rats are small-sized rat-like creatures that, despite their names, are neither moles nor rats. They are actually much closely related to guinea pigs and porcupines. These rodents are native to Africa and can be found in Kenya, Ethiopia, and Somalia.

These creatures are what scientists call eusocial animals, which means that the adults live in groups, and they together care for the young ones, and only certain individuals are allowed to produce those youngs. Bees and ants are more famous examples-this behavior is mostly seen among insects. There are only two species of mammals in the world that live like this, and both of them are species of mole rats. The female mole-rats actually fight one another for the privilege of producing the young ones; actual wars take place.

A very strange thing about mole rats is that they are unable to feel in sort of pain. Tests have been conducted on them, and they do not even react to acid burns on their skin, and they do not even treat an injured area as if it’s sensitive to touch or heat. It has been concluded that the pain receptors of mole rats are much less as compared to any other mammals, which means that the creatures can take a few punches before their bodies start to notice any sort of pain whatsoever.

Naked Mole Rats are immune to cancer, only a few out of a hundred studies have ever developed the disease. And another thing, naked mole rats do not have a point at which their bodies begin to wear out or die, they seem to possess some sort of cellular trick that helps prevent aging. Maybe this is why they have such a long lifespan and can live up to 31 years of age on average.

19. Horse

  • Lifespan: 25 to 30 Years
  • Habitat: All over the world

Horses are considered the noblest creatures, and it’s not really difficult to see why. Experts believe that the friendship between man and horse dates back from 4000 to 2000 B.C. Horses are ungulates-mammals with hooves. They have short hair, long tails, and long thick necks, muscular torsos, and elongated heads. They can be found all across the globe. Horses can live for about 25 to 30 years on average.

There are currently 400 breeds of horses. Horses can grow to be as big as 175 c from hoof to shoulder, and they weigh as much as 2200 lbs. There are also many different breeds of tiny horses, and they can be as small as 30 inches from hood to shoulder and weight only 120 lbs.

Horses are highly social animals, and they live in groups known as herds. In the wild, horses tend to live in herds of three to twenty animals, and the group is led by a mature male, which is called a stallion. The rest of the herd consists of females and their young.

Horses are herbivores, which means that they only feed on vegetation. Typically in the wild, horses eat grass, but domesticated horses are fed rolled oats, bran, hay, and barley as well. A well-fed horse will eat about 1 to 2 percent of its body weight in roughage, such as grass or hay, every day. Domesticated horses are also given blocks of minerals or salts to lick.

Unlike cows, horses only have one stomach, and it is small. In order to get enough food, a horse must graze through the day.

The gestation period of a horse is about 11 months, and some people mistake their babies as ponies, they are actually called foals. Ponies are actually adult horses that are much shorter than 56 inches. Foals can easily stand and even run after birth, and they become fully mature around 2 to 3 years of age. At the age of two, the stallion of the herd drives away the male foal, and then the young males’ band together in a group until they find a herd of females that they can lead.

20. Giraffe

  • Habitat: African Savannah and Grasslands
  • Lifespan: 25 Years

The Giraffe is actually the tallest mammal in the world, and newborn babies can be taller than most humans. They are about 4 to 5 meters high, and the tallest Giraffe had a recorded height of up to 5.9m. That’s actually over a meter higher than a double-decker bus! Thanks to their great height, they are one of the biggest pollinators in the world. As they wander around munching on high stems and leaves, they unintentionally transfer genetic material; on their muzzles from the flower from one tree to another. A giraffe can live up to 25 years of age on average.

These creatures inhabit the open plains, savannahs, and grasslands of Africa. They are most prevalent in eastern and southern Africa, but smaller, more isolated populations can be found in central and western Africa.

Giraffes are not just tall but heavy too. A single giraffe can weigh as much as 1900kg, which is more than most cars. Despite the fact that giraffes are incredibly tall, they still only have seven vertebrae in their necks. This means that the neck of a giraffe has the same amount of bones as a human.

These beautiful creatures have no teeth at the front of their top jaw, which helps them to rip the leaves from the branches, and they also have rather long tongues. They use their long tongues to feed on fruits, shoots, and leaves of tall trees and bushes.

Male giraffes also use their necks for fighting, and they swing them from side to side in order to head-butt their opponent. The spots on a giraffe’s skin are very distinct, and no two giraffes have the same pattern, this means that each animal can be individually identified from its coat.
