Animals with longest life span
Intersting facts about animals
1. TURRITOPSIS
A
Jellyfish named "Turritopsis"
lives forever as per survey conducted.
2. KOI
Koi are an ornamental, domesticated variety of
the common carp. The are common in artificial rock pools and decorative ponds.
Amazingly, some varieties are capable of living more than 200 years. The oldest
known koi was Hanako, a fish that died at the age of 226 on July 7, 1977.
3. Ocean quahog
The ocean
quahog (Arctic island) is a species of clam that is exploited
commercially.Researchers have interpreted the dark concentric rings or
bands on the shell as annual marks, much like a tree has rings. Some
collected specimens have been calculated to be more than 400 years old.
4. Antarctic sponge
Perhaps due
to the extremely low temperatures of the Antarctic Ocean, this immobile
creature has an extremely slow growth rate. Some estimate the oldest known
specimens are 1,550 years old.
5. Lamellibrachia tube worms
These
colorful deep sea creatures are tube worms (L. luymesi) that live along
hydrocarbon vents on the ocean floor. They have been known to live 170 years,
but many scientists believe there may be some that have lived for more than 250
years.
6. Red sea
urchins
The red sea urchin or Strongy locentrotus
Franciscans is found only in the Pacific Ocean, primarily along the West Coast
of North America. It lives in shallow, sometimes rocky, waters from the
low-tide line down to to 90 meters, but they stay out of extremely wavy areas.
They crawl along the ocean floor using their spines as stilts. If you
discover one, remember to respect your elders — some specimens are more than
200 years old.
7. Bowhead whales
Also known as the Arctic whale, the bowhead is by
far the longest living mammal on Earth. Some bowhead whales have been found
with the tips of ivory spears still lodged in their flesh from failed
attempts by whalers 200 years ago. The oldest known bowhead whale was at least
211 years old.
