The rhinoceros snake gets its name from the scale-covered protuberance on the tip of its snout.

Physical Description

Rhinoceros snakes change color as they age, from brownish gray to steel gray and later, at about 2 years old, to bluish green. Though it is rare, some individuals remain steel gray throughout their lives.

The function of the scaly protuberance on the tip of this snake's snout is unknown.

Size

As an adult, the rhinoceros snake is usually 39-47 inches (100-120 centimeters) long but can reach lengths of 59 inches (150 centimeters). Hatchlings are 12-14 inches (300-350 millimeters) long, and their color is brownish gray with several dorsal scales having dark edges.

Native Habitat

The rhinoceros snake is indigenous to northern Vietnam and southern China. It inhabits subtropical rainforests from elevations of 985-4,920 feet (300-1,500 meters) and has been found near streams and lakes.

Food/Eating Habits

Rhinoceros snakes eat small vertebrates. At the Smithsonian's National Zoo, they are fed mice.

Sleep Habits

This species is arboreal and mainly nocturnal.

Reproduction and Development

These snakes mate between April and May, and a clutch usually contains five to 10 eggs that hatch after about 60 days.

Conservation Efforts

Threats to rhinoceros snakes include habitat degradation and possibly collection for the pet trade. This species is present in many protected areas.
