Habitat and Ecology [top]

Habitat and Ecology:	General Triso dermopterus occurs on rocky or soft (silty-sand or mud) bottoms. Feeding Young Triso dermopterus have been observed to feed on zooplankton in the water column; feeding of adults has not yet been discovered (Heemstra and Randall 1993). Reproduction Triso dermopterus is reported to be protogynous (Heemstra and Randall 1993).
Systems:	Marine

Threats [top]

Major Threat(s):	Triso dermopterus is incidentally caught in deep-water fishing, but it is not a targeted species because it is too rare and occurs in deepwater habitats.
