Conorhynchos conirostris

Conorhynchos conirostris is a species of catfish (order Siluriformes).

The spelling of the generic name has been confused; it is currently valid as Conorhynchos as described by Pieter Bleeker in 1858.^[1] This catfish has unknown relationships. It does not appear to be assignable to any family and is placed incertae sedis.^[1] However, it has been grouped into the superfamily Pimelodoidea due to molecular evidence.^[2]

Conorhynchos conirostris originates from São Francisco River in Brazil and is considered a symbol of the river due to its endemism.^[3] This fish can reach until 100 centimetres (39 in) TL and 13 kilograms (29 lb) in weight.^[3] This fish is of commercial interest and is considered threatened by some sources.^[3]
