1. 10 Animals with the Longest life spans by Green Yatra Follow us on www.facebook.com/greenyatra www.twitter.com/greenyatra

2. Tortoises There are tortoises alive today that were 25 to 50 years old when Charles Darwin was born. There are whales swimming the oceans with 200-year-old ivory spear points embedded in their flesh. There are cold-water sponges that were filter-feeding during the days of the Roman Empire. In fact, there are a number of creatures with life spans that make the oldest living human seem like a spring chicken in comparison. Here's our list of the 10 animals with the longest life spans — and there's even an immortal animal.

3. Geo ducks 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. Follow us on www.facebook.com/greenyatra www.twitter.com/greenyatra

4. Tuataras The word "dinosaur" is commonly used to describe an old person, but when it refers to a 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 which 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 anywhere between 100 and 200 years. Follow us on www.facebook.com/greenyatra www.twitter.com/greenyatra

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. Follow us on www.facebook.com/greenyatra www.twitter.com/greenyatra

6. 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 to 90 meters, but they stay out of extremely wavy areas.

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.

8. 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. Follow us on www.facebook.com/greenyatra www.twitter.com/greenyatra

9. Tortoises Tortoises are considered the longest living vertebrates on Earth. One of their oldest known representatives was Harriet, a Galápagos 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. Follow us on www.facebook.com/greenyatra www.twitter.com/greenyatra

10. Ocean quahog The ocean quahog (Arctica islandica) is a species of clam that is exploited commercially. Follow us on www.facebook.com/greenyatra www.twitter.com/greenyatra

11. 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. Follow us on www.facebook.com/greenyatra www.twitter.com/greenyatra

12. Turritopsis nutricula jellyfish . This species of jellyfish might be the only animal in the world to have truly discovered the fountain of youth. Since it is capable of cycling from a mature adult stage to an immature polyp stage and back again, there may be no natural limit to its life span. Because they are able to bypass death, the number of individuals is spiking. Follow us on www.facebook.com/greenyatra www.twitter.com/greenyatra
