Abstract The diet of the bluenose or deepsea trevalla Hyperoglyphe porosa (Richardson) was determined from the stomach contents of 78 trevalla caught at five localities over the continental slope off south-eastern Australia (37-39° S, 142-151° E). The pelagic tunicate Pyrosoma atlanticum Peron was the most common organism present, although squids, pelagic and benthic fishes, and crustaceans were found in the stomachs of some trevalla. Trevalla are probably benthopelagic and feed mainly above the bottom during the day; at night they stop feeding and move to the bottom.
