Pseudis
''Pseudis'' is a genus of South American frogs (swimming frogs) in the family Hylidae. They are often common and frequently heard, but easily overlooked because of their camouflage and lifestyle, living in lakes, ponds, marshes and similar waters with extensive aquatic vegetation, often sitting at the surface among plants or on floating plants, but rapidly diving if disturbed. Whereas the adults are medium-sized frogs, their tadpoles are large; in some species the world's longest.Franklyn, D. (2015). . The Online Guide to the Animals of Trinidad and Tobago. Retrieved 7 January 2020 Distribution ''Pseudis'' species are distributed throughout tropical and subtropical South America, almost entirely east of the Andes (''P. paradoxa'' is the only species with populations west of the Andes, in Colombia). They are found from Trinidad to northern Argentina, being absent only in Ecuador and Chile, highland regions, and the southernmost part of South America. All species occur in Brazil, an ...

Pseudis Paradoxa
''Pseudis paradoxa'', known as the paradoxical frog or shrinking frog, is a species of hylid frog from South America. Its name refers to the very large—up to long—tadpole (the world's longest), which in turn "shrinks" during metamorphosis into an ordinary-sized frog, only about a quarter or third of its former length. Although the recordholder was a tadpole in Amapá that belonged to this species, others in the genus ''Pseudis'' also have large tadpoles and ordinary-sized adults. Distribution and habitat The species inhabits ponds, lakes, lagoons and similar waters from the Amazon and the Guianas, to Venezuela and Trinidad, with a disjunct distribution in the Magdalena River watershed in Colombia and adjacent far western Venezuela. More southerly populations from the Pantanal region to northeastern Argentina have been recognized as a subspecies, but are now often considered a full species, '' P. platensis'', although the validity of this split is questionable.

Pseudis Minuta
''Pseudis minuta'' (common name: lesser swimming frog) is a species of aquatic frog in the family Hylidae. It is found in northeastern Argentina, Uruguay, and southern Brazil, and is likely to be found in southern Paraguay. Description Males measure and females in snout–vent length. The snout is truncate in lateral profile. The fingers are slender. Hind limbs are relatively long and slender. Dorsal coloration is light green or brownish, usually with small dark blotches; sometimes a distinct light middorsal band is present. A light longitudinal stripe runs through most of the flank. The thighs have usually three distinct stripes. Males call mostly during the night, floating on the water surface and holding to vegetation. They may also call from leaves of water hyacinth ''Pontederia crassipes'' (formerly ''Eichhornia crassipes''), commonly known as common water hyacinth is an aquatic plant native to South America, naturalized throughout the world, and often invasive out ...

Tadpole
A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpoles have ...

Hylidae
Hylidae is a wide-ranging family of frogs commonly referred to as "tree frogs and their allies". However, the hylids include a diversity of frog species, many of which do not live in trees, but are terrestrial or semiaquatic. Taxonomy and systematics The earliest known fossils that can be assigned to this family are from the Cretaceous of India and the state of Wyoming in the United States. The common name of "tree frog" is a popular name for several species of the family Hylidae. However, the name "treefrog" is not unique to this family, also being used for many species in the family Rhacophoridae. The following genera are recognised in the family Hylidae: * Subfamily Hylinae ** Tribe Cophomantini *** '' Aplastodiscus'' – canebrake treefrogs *** ''Boana'' – gladiator treefrogs *** ''Bokermannohyla'' *** ''Hyloscirtus'' *** ''Myersiohyla'' *** ''Nesorohyla'' *** '' "Hyla" nicefori'' ** Tribe Dendropsophini ***''Dendropsophus'' *** '' Julianus'' *** ''Lysapsus'' †...
