Tropical marine communities are characterized by mutualistic and commensal relationships typical of alpheid shrimp (Levinton, 1982; Nybakken, 1982). The abundances of the xanthid crabs Panopeus herbstii and Eurypanopeus depressus were examined relative to surface oyster shell cover, surface oyster cluster volume, subsurface shell content, substrate sand and silt composition, and oyster reef elevation. We investigated the role played by biogenic habitats (Mytilus edulis and Crepidula spp. Supporting: 1, Mentioning: 21 - ABSTRACT: Biogenic habitat can structure marine communities by serving as both a complex substrate and food source for adult and recruiting organisms. occurred almost exclusively in the oyster habitat, sug- gesting that species with a limited ability to redistribute after metamorphosis may display a more specific selection of the adult habitat at settlement. Cataleptodius floridanus is a common small herbivorous xanthid that occurs throughout the Caribbean (Voss, 1976). Influence of biogenic habitat on the recruitment and distribution of a subtidal xanthid crab Lindsey, EL; Altieri, AH; Witman, JD; Abstract. I also explored how oyster reef habitat structure and threat from toadfish, a predator of crabs, can mediate the ecological effects of crab phenotype. Others are only sometimes seen. To determine the effects of habitat structure on conch predation by xanthid crabs, a microcosm experiment was conducted using three degrees of habitat complexity: moderate density seagrass, low density seagrass, and bare sand. Members of the subfamily Menippinae have five and sometimes six zoeal stages, but there is strong evidence that these crabs constitute a separate family (Scotto 1979). The floral egg crab has such a toxic meat that, even after being cooked, its consumption could be lethal.
