Animals living under natural conditions rarely approach their maximum possible age because of very high death rates due to infant mortality, diseases, predators, bad weather, habitat destruction, or competition for food and shelter. Here we list ten animals that would have the longest lifespans living under ideal circumstances. Lets look at the Animals With Longest lifespan.
Animals With Longest lifespan :
The largest surviving land-animals have an average lifespan of up to 70 years and a recent Zimbabwean study has found that female African elephants can potentially remain fertile until their death! Read more about elephants in our Animals A_Z section.
Bow head Whale
Bowhead whales have an average lifespan of 200 years. They can survive this long because they have a very low body temperature — and the lower an animal’s body temperature, the longer it can live.
Galapagos Giant Tortoise
The largest living species of tortoise that can survive well past a hundred, with the oldest recorded at 152. The most famous Galapagos Tortoise was ‘Lonesome George’, a sub species who lived on the Islands, he was 100 years old and still classed as a young adult! He had become an ambassador of sorts for the islands off the coast of Ecuador whose unique flora and fauna helped inspire Charles Darwin’s theories on evolution.
These sharks live farther north than any other shark species and some estimates put their lifespan at over 200 years. They also hold the world record for having the most toxic meat of any shark!
Koi fish usually live for 25-30 years but there are reports of kois that have achieved ages of 100–200 years. One famous koi in Japan, named “Hanako”, died in 1977 and a study of the growth rings of one of her scales reported that she was 226! This made her older than the United States of America!
Long Finned Eel
Native to New Zealand and Australia, these eels often live to 60 years old with the oldest living longfin recorded being 106! These eels grow very slowly, only one to two centimeters a year.
Native to South American rainforests, mangroves and savannas, macaws can live up to 60-80 years, while their breeding age ranges from 30 to 35 years. Unfortunately the majority of macaws are now endangered in the wild and a few are extinct.
Some collected specimens have been calculated to be more than 400 years old. These animals show exceptional longevity with a highest reported age, for ‘Ming’ the clam, of 507 years. It was collected alive by an expedition in 2006 so it may have lived even longer if left in the wild.
One who outlives them all, real name ‘Turritopsis Dohrnii’, this jellyfish is unique in that it exhibits a certain form of immortality; it can transform itself from an adult back into a baby through a process known as ‘trans-differentiation’, in which one type of cell transforms into another. The jellyfish turns itself into a blob-like cyst, which then develops into a polyp colony; this is the first stage in jellyfish life. Through asexual reproduction, the resulting polyp colony can spawn hundreds of genetically identical jellyfish – near perfect copies of the original adult.
