The silver-backed chevrotain is a cat-sized animal that looks like both a mouse - and a deer! It was recently spotted in Vietnam after nearly 30 years. Researchers left three camera traps in a field in the Southeast Asian country for five months and were able to capture 275 photos of the mysterious species.
