Ecology of Panulirus polyphagus

Main Ref.	Holthuis, L.B., 1991
Remarks	Subtidal (Ref. 106854). It is found on muddy substrates and sometimes on rocky bottoms near river mouths in turbid water (Ref. 4). Lives mainly at river-influenced shelf in shallow, turbid water with moderate run-off (Ref. 105109). In general, palinurids are mainly considered carnivores, usually feeding upon sluggish, easily captured animals where most material is eaten alive or freshly killed (Ref. 105260). Individuals reared in captivity fed on a natural diet of gastropods, clams, crabs, squids and fish (Ref. 105110).
