Père David's deer

Père David's deer is a Chinese deer with a sad story—it no longer lives wild in nature. It prefers munching on grasses and water plants in river valleys. This deer is special because it’s the last living species in its entire genus.

• Eats mostly grass and water plants like a picky grazer.
• Its closest living relative is Eld's deer, according to genes.
• Some scientists think it should be grouped with Cervus deer instead.
