In addition to the newly critically endangered species, the new Red List boasts a few bright spots. The future looks bright, for example, for the Arabian oryx, which not long ago nearly vanished forever.

2.Harlequin Toad

Nineteen new frogs, toads, and salamanders were added to the Red List this year, and eight are said to be critically endangered—including  harlequin toad. I suggest you to read great article on harlequin toad on green-buzz.net, where Emma Websdale explained about this frog.

3.Bog Turtle

This tiny, critically endangered bog turtle, Clemmys muhlenbergi, is one of the world’s smallest, squeezing into a 3- to 4.5-inch (7.9- to 11.4-centimeter) shell. But the eastern-U.S. reptile represents a big conservation problem. Wetland development and drainage have drastically reduced suitable habitat for this and many other species around the globe.

4. Dwarf Salamander
