Scaphiophryne
Genus of frogs from Madagascar
From Wikipedia, the free encyclopedia
Scaphiophryne is a genus of microhylid frogs endemic to Madagascar.[1] Some of the species are strikingly marked, while others are highly cryptic. They are rather plump and generally found on the ground. Several species in the genus are threatened because of habitat loss and overcollection for the international pet trade.

Behavior
Tadpoles
Tadpoles are intermediate in morphology between those of ranids and microhylids. They have rows of oral papillae, but not keratinized teeth or horny beaks.
The unique Scaphiophryne larval morphology allows for filter-feeding and the ability to use the papillae to wipe particles from substrate and churn particles from the bottom of the water source of residence.[4]
The tadpole morphology allows for distinguishing from the Pseudohemisus subgenus.[2]
Phylogeny details
The two subgenera, Scaphiophryne and Pseudohemisus, are monophyletic based on molecular analysis. The species within the Scaphiophryne subgenera are lineages that have been confirmed to be evolutionarily independent. This is based on analysis of mitochondrial and nuclear genes, where mitochondrial divergence was low, nuclear divergence was distinct, and nuclear heterozygosity was found to be high. Hybridization between species was not found, which has been previously hypothesized to happen.[2]
