Nesomantis
Thomasset's Seychelles frog or Thomasset's frog (''Sooglossus thomasseti'') is a species of frog in the family Sooglossidae. It is endemic to Seychelles. There are two known populations: one on Silhouette Island and one on Mahé Island. The natural habitats of this frog are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, rivers, and intermittent rivers. Eggs are laid among rocks and hatch into miniature adults, bypassing a larval stage. The species is threatened by habitat loss. Genetic analysis indicates that the two populations of this species are distinct from each other and are possibly even separate species. It has thus been proposed that both populations be considered evolutionary significant units An evolutionarily significant unit (ESU) is a population of organisms that is considered distinct for purposes of conservation. Delineating ESUs is important when considering conservation action. This term can apply to any species, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sooglossidae
Sooglossidae, the Seychelles frogs or Seychelles Island frogs, are a family of frogs found on the Seychelles Islands. Until recently, this family was believed to include the genera ''Sechellophryne'', '' Nesomantis'' and '' Sooglossus'', but following a major revision of amphibians in 2006, the genus ''Nesomantis'' was named a junior synonym of ''Sooglossus''. Their closest relatives are the purple frogs ( Nasikabatrachidae) of India. Description All Sooglossidae species are relatively small terrestrial frogs, about in length, hiding under fallen leaves or in rock crevices. They are unusual for the neobatrachials, in that they undertake inguinal amplexus, a primitive version of amplexus. They lay their eggs on moist ground, rather than in water. Several species lack tadpoles, with the eggs hatching directly into froglets. The tadpoles of '' S. sechellensis'' are carried, abnormally, on the backs of the female frogs until metamorphosis. There is no fossil record for the family. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
