Occurs in all kinds of habitats but is more common in vegetated areas of sheltered bays (Ref. 5595). Prefers soft, muddy bottoms but is also seen in purely rocky environments (Ref. 5595, 55922). Feeds on fish (Ref. 5595). Has been observed to mimic as dead and then feed on small fish that get close (Ref. 3817, 13371, 55922). Is usually solitary and territorial (Ref. 3817).
