These amphibians are native to Asia where they live near water. This is the home of their larvae known as tadpoles. They have specially adapted mouths which help them to eat plants at the surface.

They are carnivores which as adults feed almost exclusively on insects.

This species is restricted solely to island of Jawa where they have been subject to habitat fragmentation.

Appearance

What does the Asian horned frog look like?

The Asian horned frog is named for the small points above each eye which resemble a horn. Protruding from the front of the head is a long snout.

A pair of black spots are present at the back of the arms. Dark bands are present across the back legs.

The iris is colored dark brown with a black, vertical pupil in the middle.

Their coloration mimics that of a dead and decaying leaf with a mixture of brown shades found across the entire body. The underside is darker in color than the back.

An average Asian horned frog will measure 10-13cm (4-5.2in) long. Females are larger than males.
