Anablepsoides is a
genus of
killifish in the
familyRivulidae[3] native to tropical
South America and the
Lesser Antilles. The majority are from the
Amazon and
Orinoco basins, as well as freshwater systems in the
Guiana Shield, but a few species are from northern Venezuela, northeastern Brazil (
Tocantins River basin, as well as systems in
Ceará and
Maranhão) and the Lesser Antilles (
Trinidad and Tobago,
Grenada,
Martinique and
Margarita).[4][5] Although largely restricted to lowlands, a few species occur in the lower East
Andean foothills. They are mostly found in shallow fresh water swamps, streams, edges of rivers, ponds and pools, but a few may occur in
brackish estuaries. They are able to jump over land and breathe air for short periods, allowing them to access isolated waters inhabited by few or no other fish.[4][5] Several Anablepsoides species have small distributions and some are seriously threatened by
habitat loss; the entire known range of A. xinguensis is in the area flooded by the
Belo Monte Dam.[6]
The largest, A. igneus, is up to 15 cm (5.9 in) in
total length, but the vast majority of the Anablepsoides species only reach about half that size or less.[3]
Species
Until 2011, Anablepsoides were included in Rivulus,[4] and some prefer to maintain them in that genus.[8]
If recognized as a valid genus, there are currently 56 species in Anablepsoides:[3]
