Due to the very high mortality rate, animals hardly reach their highest age limit. The high death rate’s major cause is infant death, illnesses, predators, poor climate, habitat loss, or struggle for food and shelter.
Here we show ten animals that have the longest lifespan:
10. Red Sea Urchins
Lifespan: 100 years
Red sea urchins are identified as almost immortal animals. They Live in the Northeast Pacific Ocean’s shallow-water from Alaska to the West Coast of North America. These Skinny animals don’t have a heart or brain. The lifespan of these small, spikey animals can reach up to 100-200 years. Californian red sea urchins can live up to 50 years; but, these skinny-spiked creatures of British Columbia, Canada, can live more than 100 years. According to studies, the Canadian urchins over 7.5 in (19cm) in diameter can probably live about 200 years.
9. Koi Fish
Lifespan: 25-35 years
Originated from Eastern Asia, Koi Fish usually live in freshwater. People of Japan believe that the Koi Fish is a symbol of wealth, good fortune, and prosperity. According to some reports, the expected lifespan for a Koi fish is about 30 years old, but many koi fish have reached over 200 years old! One legendary Koi in Japan, named “Hanako,” was hatched in 1751 and died in 1977, and a study shows that she was 226 years old. The most extended lifespan for any fish of this kind.
8. Longfin Eel
Lifespan: 60 years
Longfin Eels are found in New Zealand and Australia, and They live in freshwater like lakes, rivers, etc. They can grow up to around 1.2 m-2 m in length. Longfin Eels are omnivorous creatures. They are known as opportunistic hunters whose prey includes small fishes, fish eggs, mice, trouts, little birds, and ducklings. Eels usually live up to 60 years old. The longest age ever recorded of a Longfin Eel is 106 years old. They grow very slowly, due to which they can grow so old.
Lifespan: 60 years
Macaws are the most easily recognizable and beautiful birds in the world. Belonging to the Parrot Family, these Long Tailed, Colorful, and entertaining birds are acknowledged as Loyal Companions, and they are being kept as pets for so long. There are many types of Macaws globally, each having different likes, dislikes, and personalities. The average lifespan of Macaws is up to 60 years, But Macaws can live up to 80 years or even more if properly taken care of.
6. African Elephants
Lifespan: 70 years
Only two elephant species are left in the World: African and Asian Elephants. African Elephants are known as strong, smart, and social creatures. They are the largest living mammals on land. The trunk of elephants is so strong and precise that it can carry heavy weights and is used for many delicate works. Its size is slightly large and has big ears than Asian Elephants. These Elephants have an average lifespan of 70 years.
5. Galapagos Giant Tortoise
Lifespan: 100 years
The largest species of tortoise family is Galapagos Giant Tortoise. These Massive Tortoises can weigh above or up to 400 kg. They are one of the longest-living vertebrates with over 100 years in the wild, the longest recorded as 152 years. Considered one of the laziest animals, they sleep nearly 16 hours a day. ”Lonesome George” a famous Galapagos Tortoise who lived on the Islands, over 100 years old and still known as a young adult.
4. Bowhead Whales
Lifespan: Over 200 years
One of the world’s longest-living mammals is Bowhead Whales. They are named after their huge bow-shaped mouth that looks like they are smiling. They live in the harsh Arctic seas, all year round in the cold. Bowhead Whales use beautiful sounds to communicate with each other. They can grow up to 60ft (18m) in length, and their weight can reach up to 100 tonnes. They consume up to 2 tonnes of food daily. Studies show that Bowhead whales can live up to 200 years.
3. Greenland Sharks
Lifespan: 400 years
Greenland sharks are one of the world’s biggest sharks, compared to white sharks. They grow 6.4 meters (21 feet) long and weigh nearly about 1,000 kg (2,100 pounds), though the weight of the typical ones are around 400 kg (880 pounds), and they are about 2.5 to 5 meters in length. Greenland sharks can reach the age of up to 200 years old, although one shark found the oldest vertebrate in the world that reached nearly 400 years old. They grow very slowly, about 1 cm in a year, and reach maturity at about 100 years, due to which they live so long.
2. Ocean Quahog
Lifespan: 200 Years
The longest living mollusk known is the Ocean Quahog. It’s inhabited in sandy and muddy lands from 10 to 280 meters deep across Scotland. Some species have been measured to be more than 400-years-old. These animals have rare longevity with the highest recorded age of 507 years. The clam is called Ming so because it has been living during the Ming Chinese Dynasty. It recorded in the Guinness book of records as the world’s oldest animal. The quahog clam swallows small plants called phytoplankton that live in the ocean. They eat by pumping water into their body. This is actually a variety of edible clams with a solid shell.
1. Immortal Jellyfish
Lifespan: Endless (if it dies, its cells again fall into the polyps, not into a new medusa, and new jellyfish emerge from these polyps.)
To date, there are only one species that has been known as ‘biologically immortal’: the jellyfish Turritopsis Dohrnii. This Immortal Jellyfish can regenerate itself if its body starts to deteriorate through damage or age. These tiny, transparent animals live in oceans across the globe, and they can revert themselves into the early stage of their life cycle. Turritopsis Dohrnii is predatory species, and its diet mainly consists of fish eggs, plankton, and small mollusks. Turritopsis Dohrnii hunts their prey by using their tentacles. The stinging cells contained in its tentacles are called nematocysts. Like other jellyfish, Turritopsis Dohrnii uses its bell to bring its prey closer to its tentacles.
