Ecology of Palaemonetes varians

Main Ref.	Dolmen, D., J. Hindley and E. Kleiven, 2004
Remarks	Occurs in brackish water lakes and shallow coastal lagoons with salinity from 0.9 to 25.3 (Ref. 2745). Prefers stagnant and slow-running waters, irrigation channels and salt marshes (Ref. 2792). Associated with Palaemon elegans and/or Palaemon adspersus (Ref. 2745). Detritivores; with a varied diet characterized by scavenging and opportunistic feeding behavior (Ref. 2838).
