Snakes (Serpentes): 50 accepted records for the country in total (1 of these not yet 'officially' documented). (Of these 50 records, 45 are from Trinidad and 22 are from Tobago, with 5 of those from Tobago not being recorded from Trinidad. Of the 50 records for the country, 7 species are known from just 1 or 2 records. In addition to the 50 generally accepted confirmed records, there are at least 2 dubious records). A number of frogs and toads inhabit the islands, including the well known huge marine or cane toad (Rhinella marina), locally known as the crapaud on both islands, and the tiny colourful rare endemic species known as the El Tucuche golden tree frog (Phytotriades auratus), found only in the giant epiphitic bromeliads at the mist-shrouded summits of Trinidad's two highest peaks, as well as the Mount Tucuche tree frog (Flectonotus fitzgeraldi), found in the Northern and Central Ranges of Trinidad and throughout most of Tobago. In the same genus as the marine toad, the Rivero's toad (Rhinella humboldti) is found in the cane fields, rice fields and other open agricultural areas of Trinidad (absent in Tobago). The strangest of all Trinidad's frogs is the highly aquatic Suriname toad or pipa toad (Pipa pipa), the tadpoles of which develop in the skin tissue of the mother's back, before bursting out and emerging as miniature replicas of the adult frogs. Another unusual frog found in Trinidad is the paradoxical frog (Pseudis paradoxa) in which the tadpoles of the species are approximately 25 cm long and the adults shrink to about 6.5 - 7.5 cm; this reduction of size from the tadpole to the sexually mature adult is how the species received its common name. The Amazon River frog (Lithobates palmipes) is found near ponds, slow flowing rivers and other permanent water sources, usually in tropical forests, in the Central Range of Trinidad (not located in Tobago). The giant tree frog (Boana boans), known locally as the giant flying frog, is commonly heard calling after dusk from the vegetation along forest-lined streams in Trinidad. Other frogs of the same genus include the map tree frog (Boana geographica) and the banana tree dwelling frog (Boana platanera) (both found on both islands), as well as the polka-dot tree frog (Boana punctata) which is native to Trinidad, not Tobago. Other frogs in the family Hylidae include species in the genus Dendropsophus (D.
