Appearance
The adult male frog is 63 to 68 mm long from nose to rear end and the adult female frog is 75 to 76 mm long. The hind legs are about one and a half times as long as the body. It has vomerine teeth and a large tongue. It has a fold of skin on each side of its body, running from the eye down to the hip. This frog has a brown or yellow-brown back and a white belly.[1]
Life cyle
The female frog lays eggs in rice fields and streams where the water does not move quickly. The tadpoles are silver-white in color. They have stripes running from their noses to their eyes and a dark spot behind each eye.[1]
Chemicals
This frog makes chemicals on its skin. It makes (Val1)-bradykinin to stop larger animals from eating it. It also has antibiotics on its skin: guentherin, brevinin-2GHa, brevinin-2GHb, brevinin-2GHc, and temporin-GH.[1]
Danger to humans
The parasite Angiostrongylus cantonensis, or rat lungworm, can live in this frog. This parasite gives humans the disease angiostrongyliasis[1] and makes the membranes around the brain swell, which is very dangerous.[4]
