Also known as Bocourt's terrific skink, the terror skink is a lizard with uniquely long, curved teeth. It was rediscovered in 2003 after last being sighted in 1876. That 1876 sighting was of just one solitary skink, so scientists assumed that the species had died out shortly thereafter.
It was seen then on an uninhabited small island called New Caledonia in the South Pacific Ocean. Now it has been confirmed to exist on similar small islands in the South Pacific, so if you ever take a sunny cruise down that way, look out for terror skinks! They're considered a top predator.
