Captive bred Blue-tailed skink
Although extinct in the wild, there are currently two captive breeding populations. One on Christmas Island and the other at Taronga Zoo in Sydney, Australia. Scientists are hoping to be able to successfully re-populate the island. Photo credit to Hamish Noller https://www.instagram.com/hamwildo/

The blue-tailed is a species of skink, a lizard native to Australia's Christmas Island, and is not closely related to the ''Plestiodon'' skinks of North America, whose juveniles are known for their blue tails. It is relatively small with a black body with yellow stripes going to a bright blue tail.
