"Endemic to the forests of south and southeast Asia, the silver-backed chevrotain, or Vietnamese mouse-deer, is one of the world's most elusive animals. The rabbit-sized critter is only known to science through five specimens, four of which were recorded by researchers in 1910. The fifth was killed by a hunter and donated to scientists in 1990. Since then, there have been no recorded sightings of the animals, leading many to fear they had gone extinct. Now, thanks to the efforts and persistence of a team led by biologist Andrew Tilker, the species has not only been rediscovered but also photographed in the wild for the first time!
"It's a really cool species, and we'd long hoped to find the proof they were still around," says Tilker, a doctoral student with the Leibniz Institute for Zoo and Wildlife Research in Germany.
The animal, which looks like a hybrid between a mouse and a deer, is the smallest member of the hoofed ungulate family, which includes deer, giraffes, sheep, llamas, and many others. They live alone, or in pairs, and have a distinguishing silver sheen on their rumps, along with tusk-like incisors. Because chevrotains lack horns and antlers, and the teeth are unusually long in males, scientists believe the "fangs" are used to compete for territory and mates."
