Sternopygus J. P. Müller & Troschel, 1849 |
Sternopygus is a genus of glass knifefishes found in tropical and subtropical South America (south to the Río de la Plata Basin), and Panama. They inhabit a wide range of freshwater habitats, from fast-flowing rivers to essentially static waters in floodplains, and shallow habitats to the bottom of deep rivers. S. macrurus will even visit brackish mangrove to feed. [1]
They are medium to large knifefish, with a maximum total length of 23–140 cm (0.8–4.6 ft) depending on the exact species. [1] [2] They feed on invertebrates, small fish and fruits. [1] Most members of Gymnotiformes are nocturnal, but Sternopygus are both nocturnal [1] and diurnal. [3]
There are currently eleven recognized species in this genus. [2] [4] [5]
