Mouse or deer? The chevrotain or mouse deer (family Tragulidae) is one of the world’s smallest ungulates. This diminutive critter typically reaches weights of only 4.4 lbs (2 kg)—about the size of a chihuahua! Unlike many other deer, it has no antlers. Instead, males rely on fang-like canine teeth to defend themselves from foes. This species can be seen in parts of Southeast Asia, including Vietnam, where it enjoys a diet that includes fungi and fallen fruit.
