Hemisus barotseensis |
The shovelnose frogs are nine species of frog in the genus, Hemisus, the only genus in the Family (biology) Hemisotidae. They are found in tropical and subtropical sub-Saharan Africa. The shovelnose frogs are moderate sized frogs, reaching a length of 8 centimetres (3.1 in). They are round-bodied, with short legs. Their head is small and narrow, with a hard, upturned nose1.
The shovelnose frogs are burrowing frogs, living most of their life underground. The female will dig underground while it is in amplexus, and lay the eggs in an underground cavity. The male will leave through the tunnel, and the female will remain with the eggs. Once sufficient rain has fallen, the female will burrow, with her nose, towards a water source where the tadpoles will remain until metamorphosis1. The tadpoles may remain out of water for up to a few days.
Unlike most burrowing frogs, the shovelnose frogs burrow head first, as opposed to rear first. Some species are kept as pets.
