Etymology: Pseudoplatystoma: Greek, pseudes = false + Greek, platys = flat + Greek, stoma = mouth (Ref. 45335).

Issue
We believe based on the original description, plate, and locality that Platystoma truncatum is a synonym of Pseudoplatystoma tigrinum. We have retained the younger name P. tigrinum (Valenciennes, 1840) for purposes of stability, there has been virtually no use of P. truncatum since its original description, thus we treat it as a Nomen oblitum. For reproductive biology and ecology, see Loubens and Panfili (2000).

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.
出現於河口的區域, 主要地向上游水流最急的地方向上到流域的河川源頭。 生活在主要床中的夜行的種慢地或快速的區域, 以及在被水淹沒的森林中, 特別地稚魚。, 隨機又以魚為食的魚那可能吃螃蟹與蝦。 在乾季末端，他們能與他們的獵物同時移動, 然後在雨季結束的時候返回.(參考文獻 35381) 在 Guapore 與 Marmore 河的刺網漁場中的最重要的鯰魚。
