hello my followers! i my intention is to inform you ,to satisfy your curoisity,
Here we list ten animals that would have the longest lifespans living under ideal circumstances.
African Elephant
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.
Bowhead 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.
Greenland Shark
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
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.
Macaw
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.
Ocean Quahog
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.
Immortal Jellyfish
One who outlives them all, real name 'Potpourris 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 of original adult.
