FBname: Tiger sorubim
Remark: We believe based on the original description, plate, and locality that <i>Platystoma truncatum</i> is a synonym of <i>Pseudoplatystoma tigrinum</i>. We have retained the younger name <i>P. tigrinum</i> (Valenciennes, 1840) for purposes of stability, there has been virtually no use of <i>P. truncatum</i> since its original description, thus we treat it as a Nomen oblitum. For reproductive biology and ecology, see Loubens and Panfili (2000).
Comments: Occurs in estuarine zones, mainly upstream of the first rapids up to the basin's headwaters.  Nocturnal species which lives in the main bed of slow or fast zones, as well as in the flooded forests, particularly the juveniles., Opportunistic, piscivorous fish which may feed on crabs and shrimps.  At the end of the dry season, they can migrate at the same time as their prey, then return at the end of the rainy season (Ref. 35381).  Most important catfish in gill-net fisheries of Guaporé and Mamoré rivers.
