Sturisoma aureum

Sturisoma aureum
Giant Whiptail Catfish
Young Sturisoma of any species are difficult to distinguish. S. aureum can be distinguished from most congeners by the black horizontal markings behind the first dorsal ray, that are solid vice speckled. It also appears to be the smallest member of the genus rarely reaching over six inches in length. S. aureum, when in good condition, has a long trailing fin extension from the upper caudal lobe.
Males sport conspicuous odontodes along the sides of the head and rostrum.
