Ecology of Palaemonetes pugio

Main Ref.	Williams, A.B., L.G. Abele, D.L. Felder, H.H. Hobbs Jr., R.B. Manning, P.A. McLaughlin and I. Pérez Farfante, 1988
Remarks	Often found near underwater structures and dense stands of aquatic macrophytes in shallow areas of estuaries. Movement and distributional patterns likely influenced by both photoperiod and tidal cycles. Mainly detritivorous; also feeds on epiphytic microalgae and prey on meiofauna and small infaunal polychaetes, oligochaetes, nematodes, epiphytic fauna, and mysids. Preyed upon by various estuarine fishes and other aquatic carnivores. Host to numerous species of parasites and ectocommensals, primarily coccidia, microsporidians, trematodes, isopods, and leeches (Ref. 96311).
