Primarily a shallow-water benthic species, but recorded down to 153 m. It is found on sand, rubble or grassy areas near reefs and grass beds, near a source of mound-building material. Tunnel entrances can reach up to three metres in diameter, with the tunnel narrow and mounds near reefs and grass beds. It builds mounds of sand, coral rubble and shell fragments found excavated around the tunnel entrance. It feeds mainly on stomatopods ( Mantis Shrimps), fishes, polychaete worms, chitons, sea urchins, sea stars, amphipods and shrimps. The maximum size is about 60 cm, common to 45 cm. Males are usually larger than females
Males are usually larger than females. It is a protogynous hermaphrodite, forming harems with occasional monogamous mating systems. Females each defend a feeding territory surrounding their home burrow and males control larger territories that encompass the defended areas of up to six females. Males have territories of about 1,000m2 with females to 250m2. It spawns above the bottom at dusk.
