Solitary or in groups of 2 or 3 individuals but never in schools (Ref. 35237). Inhabits shallow inshore waters usually on soft bottoms. Frequently found in freshwater (Ref. 13608). When threatened, it becomes inflated like a balloon, in order to ward off predators. Carnivorous, feeding mainly on mollusks which crushes with its powerful teeth (Ref. 35237). Of negligible commercial importance and usually not marketed (Ref. 5217).
獨居性或形成 2 或 3 個體的群體但是從不成群.(參考文獻 35237) 在軟質底部上通常棲息於沿岸淺水區水域。 時常發現於淡水了。 (參考文獻 13608) 當危險時，它變成膨脹像一個氣球,為了守衛外海的掠食者。 肉食性, 主要捕食壓碎用它的有力齒的軟體動物。 (參考文獻 35237) 可以忽略的商業重要性而且通常不在市場上銷售.(參考文獻 5217)
