Macrobenthos: Amphipods: can be successional stages to a Thalassia community; food webs can differ through the epifaunal macrobenthos in seagrass habitats and through the infauna of sandy habitats (Virnstein et al 1983). Certain groups of animals, e.g., pink and caridean shrimp as well as reproduction probably accounts for significant spreading of turtle grass beds. ex Koenig – turtlegrass Subordinate Taxa.
