Surubi

Pseudoplatystoma is a genus of several South American catfish species of family Pimelodidae. The species are known by a number of different common names. They typically inhabit major rivers where they prefer the main channels and tend to stay at maximum depth, but some species can also be seen in lakes, flooded forests, and other freshwater habitats. They have robust bodies, and are important food fish. Recently, their population size has been on the drastic decline due to a variety of factors including overfishing and habitat destruction due to the construction of hydroelectric dams. In their native waters, these fish may be called surubí in Guaraní. Specially in Paraguay- a country that still speaks both Spanish and Guaraní- This name is also used in some Spanish-speaking countries and in Brazil . In Peruvian Spanish, they are called doncella or zúngaro. P. corruscans may be called moleque or pintado. They often are referred to in the vernacular as bagre rayado/rajado or pintadillo/pintado (tiger catfish or tiger–shovelnose). P. corruscans, P. fasciatum, and P. tigrinum are also known as spotted sorubim, barred sorubim, and tiger sorubim, respectively. This genus contains the fish commonly known as the tiger shovelnose catfish in the aquarium hobby, though the species in this genus are relatively easy to confuse.
