Trevallies Lair is a sloping reef in Batanes named for the resident giant trevally that hunt along its edge. It is a mid-depth boat dive where schools of jacks and the odd barracuda cross the slope, and the strength of the current changes with the tide.

The dive

The slope runs from 12 m down to 25 m, and the giant trevally (Caranx ignobilis) patrol its edge, picking off smaller fish. Schools of jacks pass through over the reef, with an occasional barracuda among them. Current here ranges from mild to moderate depending on the tidal phase, and it picks up to moderate or strong on spring tides.
