10 of the Longest Living Animals on Planet Earth

7. Tube Worms

Colorful tube worms lining the hydrocarbon vents of the ocean floor have been estimated by scientists to live around a 175 years. Certain kinds of them have also been recorded to have lived around 250 years or more.

8. Red Sea Urchins

Sea urchins are prickly, spindly looking creatures that you might have a hard time believing are actually alive. But, oh boy, they surely are alive, and probably will even outlive you! These particular ones, named red sea urchins because of their color, are said to live up to a 100 years. Fascinatingly, they do not show any biological signs of aging as they get older, and also have the ability to regenerate their tissues, like a lizard or starfish.

9. Sea Sponges

Another sea creature that sound incredibly made up is the sea sponge. Yes, its alive, and yes, it lives a long, long, time. About 11,000 years to be exact! And to think it doesn’t even move throughout its entirely lifetime is pretty incredible.

10. African Elephant

Most animals we’ve seen so far have been sea creatures or reptiles, but one of the longest living land mammals is the African elephant. With an average life span of about 70-80 years, these gentle giants live long, happy lives just like us humans!
