Lives mainly in coastal waters in seagrass meadows and along mangroves (Ref. 115276), and intertidal mudflats (Ref. 128960). Found under rocks and in rock pools, on sandy or muddy substrate (Ref. 111207). Larger biomass is seen between depths of 2 to 15 m. Small juveniles are found in very shallow waters (less than 1 m); females occupy deep-water zones during spawning (Ref. 115276). Opportunistic predator, primarily a carnivore preying on a variety of benthic animals and less marine plants and seagrass (Ref. 108412). Prolific predators of bivalves. Some suggested that they're opportunistic omnivores or detritivores, feeding on carrion, especially on fishing-discards. Efficient night time forager, using a characteristic zigzag search pattern to locate prey (Ref. 115276).
