Terror Skink
Up until 2003, this rather rare reptile (whoa, tongue twister) was believed to be extinct. Maybe that’s because it can only be found in the lovely Isle of Pines. When the skink was released by specialists at the French National Museum of Natural History, it was only known by one specimen.
The Clarion Nightsnake
For 80 years, the Clarion nightsnake hid from the public eye and it did so well at hiding biologists erased it from any scientific record. Until it was found again on a remote island off the coast of Mexico.
