12 Oldest Animals In The World

Meet 12 of the world’s oldest animals!

Several of these ancient species, believed to be extinct, have recently surfaced and were rediscovered. These animals did not undergo any significant changes despite millions of years of evolution. And yes, most of them are from the deepest corners of the ocean.

Here are the 12 living fossils of the world:

 
1. Coelacanth
Coelacanths were thought to be extinct, disappearing from the fossil record 410 million years ago. But in 1938, they were rediscovered when one got caught off the coast in South Africa. A second Coelacanth was found in 1999 in Indonesia.

2. Frilled Shark
Often termed as a living fossil, the frilled shark swims near the bottom of the Atlantic and Pacific Oceans. Only 2 of its kind were ever seen and both were accidentally caught in fishing nets from the deep sea. Both were also caught near the coast of Japan in the late 19th century and in 2007.

3. Sturgeon
Sturgeons have been in existence for 200 million years. Sturgeon is a common term used to refer to over 20 species of fish and several closely related species which include beluga and sterlet. Due to their long reproductive cycles, sensitivity to environmental conditions, water pollution, over fishing, and poaching, the sturgeon population is noticeably declining, especially since the demand for caviar is on a rise. According to the International Union for Conservation of Nature or IUCN, 85% of sturgeon species are at risk of extinction.
