All of the species are relatively small terrestrial frogs, about (convert|4|cm|in}} in length, hiding under fallen leaves or in rock crevices. They are unusual for the Neobatrachials, in that they undertaking inguinal amplexus, a primitive version of amplexus. They lay their eggs on moist ground, rather than in water. One species lacks tadpoles, with the eggs hatching directly into miniature frogs, while the others carry the tadpoles on their backs until their metamorphose.
There is no fossil record for the family. The two genera's ancestors diverged when the Seychelles Islands split from India about 100 million ago.
