Often nocturnal or crepuscular (active at dawn/dusk). Night dives significantly increase chances of seeing them out hunting. Can be seen year-round, seasonality less of a factor than time of day.
Wide tolerance depending on the specific region within temperate to tropical zones.
Look in crevices, under rocks, inside empty shells or discarded human debris (jars, tires) on reefs or rubble/sandy bottoms. They are masters of camouflage; look for unusual shapes or textures, or discarded shells from their meals (crab shells often indicate a den nearby). Move slowly and avoid bright lights directly in their eyes.
