Remarks | On intertidal flats and seaside lagoons (Ref. 104331). Inhabits sand and sand-mud bottoms, often entirely buried in sediments. Sometimes seen on mussel or oyster beds while foraging. Active at low light, mostly at night during summer months. Both an active predator and scavenger. Capable of readily detecting food in its vicinity (Ref. 101546) by sensing the water the prey pumps out (Ref. 105269). Primarily feeds on bivalves (Ref. 101546) such as mussels and oysters (Ref. 105269). |
