Corythomantis greeningi
The adult male frog is about 7.3 cm long from nose to rear end and the adult female frog is about 8.7 cm long.  The male frog weighs about 21 grams and the female frog 41 grams.  Its skin is rough and warty.  It has chemicals on its skin that scientists think might be poison.  The poison might keep other animals from eating the frog.  All adult frogs are brown in color, but the adult female frog has dark marks on her back and the adult male frog does not.  The frog's head looks like tree bark.
