Lesser Mouse-deer
Tragulus javanicus
Summary 4
The Java mouse-deer (Tragulus javanicus), is a species of even-toed ungulate in the Tragulidae family. At maturity it is about the size of a rabbit, making it one of the smallest ungulates. It is found in forests in Java and perhaps Bali. It formerly included the more widespread T. kanchil and the poorly known T. williamsoni as a subspecies.
Habitat 5
Tragulus javanicus are found in overgrown primary and secondary forests in southeast Asia. They often reside around rocks, hollow trees, and dense vegetation near water.
Habitat Regions: tropical ; terrestrial
Terrestrial Biomes: rainforest
Physical description 6
Tragulus javanicus, or lesser Malay mouse deer, do not have antlers or horns. Instead, adult males have elongated, tusk-like upper canines (Nowak and Paradiso, 1983). These canines protrude from the side of the mouth. Females lack these canines. Females are also smaller than the males (Nowak and Paradiso, 1983). The cheekteeth of lesser mouse deer have a crescent pattern formed by the enamel ridges. Mouse deer have no upper incisors. The pelage of mouse deer is brown with an orange tint. The underside is white. There is also a series of white vertical markings on the neck (Grzimck, 1994). Malay mouse deer have a triangular head and a round body with elevated rear quarters. The thin legs are about the diameter of a pencil (Nowak and Parasido, 1983). T. javanicus is the smallest artiodactyl, 18-22 inches long with a tail length of 2 inches (Grzimck, 1994). The young look like miniature adults when born; however, the tusk-like incisors in the infant males are not well developed.
Range mass: 1 to 2 kg.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: male larger
Average basal metabolic rate: 4.883 W.
