Pseudoplatystoma corruscans

The spotted sorubim (Pseudoplatystoma corruscans), also called the spotted surubi or pintado, is a large long-whiskered catfish of the family Pimelodidae, native to the São Francisco and La Plata river basins of South America. Its range runs through Argentina, Brazil, Paraguay and Uruguay. Adults commonly reach 160 to 200 centimetres in total length and weights of up to about 120 kilograms, with females growing larger than males. The back is dark olive brown with extensive spotting over the body and fins, the belly is pale cream to white, and the wide, flattened head carries two pairs of barbels. It is a nocturnal, piscivorous ambush predator that migrates upstream to nursery areas between October and January as flood cycles begin. Its boneless flesh makes it an important food fish in Brazil. The IUCN lists it as Near Threatened because of heavy fishing, dams that fragment its habitat, and fertile hybrids escaping from aquaculture.
