Title : Longest Living Animals Previous topic PreviousNext Next topic

Geoducks - First on the list are these large saltwater clams that are native to the Puget Sound and have been known to live for at least 160 years. They are characterized by their long 'necks', or siphons, which can grow to over 1 meter long.

Tuatara - The word "dinosaur" is commonly used to describe an old person, but when it refers to tuataras, the term is as literal as it is metaphorical. The two species of tuatara alive today are the only surviving members of an order that flourished about 200 million years ago — they are living dinosaurs. They are also among the longest-lived vertebrates on Earth, with some individuals living for between 100 and 200 years.

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.

Cyprine Arctica Islandica or Quahog - A creature with longest lifespan ever recorded is Quahog. A specimen of the Icelandic Cyprine Arctica islandica (also known as an ocean quahog), a mollusk, was found to have lived 405 years and possibly up to 410. Another specimen had a recorded lifespan of 374 years. In 2006 and 2007, separate specimens collected off the coast of Iceland were found to be more than 400 years old, making the Arctica islandica clam the longest-lived animal species ever recorded.

Koi - Koi are an ornamental, domesticated variety of the common carp. They 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.

Tortoises - Tortoises are considered the longest living vertebrates on Earth. One of their oldest known representatives was Harriet, a Galapagos tortoise that died of heart failure at the age of 175 years in June 2006 at a zoo owned by the late Steve Irwin. Harriet was considered the last living representative of Darwin's epic voyage on the HMS Beagle. An Aldabra giant tortoise named Adwaita died at the rumored age of 250 in March 2006.
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.

Bowhead whales – 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.

Red sea urchins - The red sea urchin or Strongylocentrotus franciscanus 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 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.

Blue-and-Yellow Macaw - Amongst the birds, macaw has the longest lifespan. Charlie (hatched c. 1899), also known as Charlie the Curser, is a Blue-and-yellow macaw living at Heathfield Nurseries, a pet sanctuary in Reigate, Surrey, England. Charlie became famous when The Daily Mirror published an article about her in January 2004; she is 109-year old.
