A few nice endangered animals images I found:
Queen of Gir
Image by Peter L Barker
An Asiatic lioness. A very rare specimen of Asiatic Lion. Their are believed to be about 150 in total of these rare lions left. All the wild ones known live in the Gir National Forrest in Gujarat India. They are carefully protected but the survival is far from sure.
