Ecology Summary - Tetronarce cowleyi

Language:

Main Ref.	Ebert, D.A., D.L. Haas and M.R. De Carvalho, 2015
Remarks	This species is mostly found along the outer continental shelf and upper slope near the bottom, but also well off it and at bottom depths of 110-457 m (Ref. 100734). The limited capture of this electric ray in bottom trawls is suspected to be not indicative of its abundance in the area, but rather by its ability to move well off the bottom while foraging for fish and other large prey; diet consists mainly of large bottom and pelagic bony fishes and small sharks (Ref. 100734).
