Pseudis
''Pseudis'' is a genus of frogs (swimming frogs) in the Hylidae family, and are found in the Guianas, Colombia, Venezuela, Trinidad, Brazil, Paraguay, southeastern Peru, eastern Bolivia, northeastern Argentina, and Uruguay.〔 ''Pseudis'' species are distributed throughout tropical and subtropical South America, almost entirely east of the Andes (''P. paradoxa'' is the only species with population west of the Andes). They are commonly found in ponds associated with river floodplains, from Trinidad to northern Argentina, being absent only in Ecuador and Chile, highland regions, and the southernmost part of South America. Most species occur in Brazil, and ''P. fusca'', ''P. tocantins'', ''P. cardosoi'', and ''P. bolbodactyla'' are endemic to this country. ==Description== These frogs have several adaptations to aquatic life, such as protuberant eyes, robust hind limbs, and fully webbed feet.〔 Nevertheless, they belong to the "true" tree frogs, family Hylidae.〔 These frogs are commonly known because their giant tadpoles can reach up to . They are closely related to a second genus, ''Lysapsus'', that lacks giant tadpoles and in which adults are smaller, up to , compared to up to in ''Pseudis''.〔 ''Lysapsus'' has been considered a synonym of ''Pseudis'', but molecular evidence support their separateness.〔
