Abstract

The objective of the present study was to characterize the composition and abundance of the marine brachyuran crabs in non-consolidated sublittoral sediments in two regions, Ubatuba and Caraguatatuba, on the northern coast of São Paulo State, Brazil. In each region, collections were made monthly at seven depths for two years, July 2001 through to June 2003, from a fishing boat equipped with two double-rig nets. A total of 30,231 crabs were caught (13,305 at Ubatuba and 16,926 at Caraguatatuba), representing nine superfamilies (Dromioidea, Homoloidea, Calappoidea, Leucosioidea, Majoidea, Parthenopoidea, Portunoidea, Xanthoidea and Pinnotheroidea), 16 families, 29 genera and 44 species. Among the total species collected, 31 were common to both regions. Caraguatatuba showed higher species richness (42) and a higher H' diversity index (2.93). For both regions, Callinectes ornatus, Hepatus pudibundus and Libinia spinosa were the most abundant brachyurans. The results indicate that the two regions provide favorable environments for brachyurans, resulting in a locally high biodiversity.
