A first report of crustaceans (Anomura and Brachyura) from Laje de Santos: A no-take marine reserve in southeast coast of Brazil

This study represents an unprecedented effort to assess the diversity of rocky infralittoral decapod Brachyura and Anomura from Laje de Santos Marine State Park, a preserved protected area along southeastern Brazilian coast. The samples were carried out quarterly for one year, using combination artificial refuge substrate passive capture specimens SCUBA dive active capture. Specimens sampled deposited in Crustacean Collection Department Biology FFCLRP, University São Paulo. abundance richness is expressive considering dimension with total 987 individuals distributed into 32 species, 22 genera, 11 families. hermit crab Pagurus brevidactylus Mithraculus forceps most abundant species Brachyura, respectively. first focused on carcinofauna inhabiting park we encourage future works monitoring as well construction new robust checklists contents different offshore regions order build biodiversity parameters serve baseline management work plans areas since crustaceans are key group fauna composition any subtidal ecosystem.
