“…The ornamental crab Mithraculus forceps was the most dominant and abundant crab, as also found on rocky shores of the southeastern and southern coast of Brazil by SCUBA divers (Gaeta et al, 2011) and manual sampling (Mantelatto et al, 2004;Bouzon and Freire, 2007). The dominance of M. forceps in shallow hard-bottom areas is probably due to: short larval stage, high survival rate of juveniles and rapid growth (Rhyne et al, 2005); high reproductive effort and growth stimulated by warm water (Mantelatto et al, 2004;Rhyne et al, 2005;Figueiredo et al, 2008); as well as herbivorous feeding habit (Figueiredo et al, 2008); and possibly effective defense strategies and an absence of large predators.…”

This study investigated the composition and spatial distribution of the sublittoral decapods on the reefs of Porto de Galinhas Beach, southern coast of Pernambuco, Brazil, through the Underwater Visual Census technique. Data were collected monthly, at night during full-moon tides in low tide periods from June 2004 to May 2005, using SCUBA diving and a visual census with a fixed belt transect (20 m long). Three sampling areas were defined: Confined Waters (low hydrodynamics) with shallow sites (up to 2.5 m deep); Semi-open Water (3 to 6 m deep), influenced by waves and tidal currents (moderate hydrodynamics); and Open Water (7 to 10 m deep), in the breaker zone (high hydrodynamics). A total of 6,287 individuals of 34 species belonging to the infraorders Brachyura (19 species), Achelata and Anomura (5 species each), Caridea (3 species), and Stenopodidea and Astacidea (1 species each) were collected. Two decapod assemblages were distinguished: in a habitat with low hydrodynamics and shallow (Confined) water; and in a habitat with moderate to high hydrodynamics and depths of 3 to 10 m (Semi-open and Open water). At the sites with high hydrodynamics, i.e., the Open-water Area in the breaker zone, decapod diversity was significantly lower than in the other, protected areas on the reef bench. These results suggest that the distribution of subtidal decapods on coastal reefs is influenced by depth and exposure to water stress caused by waves and currents (hydrodynamics). The visual census technique with SCUBA proved to be suitable for ecological studies on subtidal decapods.

“…These species are commonly found associated with algae on coral reefs or rocky shores and coral reefs (Melo, 1996), and were also collected in the daytime by SCUBA divers in southeast and southern Brazil (Mantelatto et al, 2004;Bouzon and Freire, 2007).…”

“…The biodiversity of different groups of Decapoda in the region of Ubatuba has been extensively studied, for instance by Fransozo et al (1992 and1998), NegreirosFransozo et al (1992 and, Pires (1992), Cobo et al (1993), Hebling et al (1994), Nakagaki et al (1995), NegreirosFransozo & Nakagaki (1998), Costa et al (2000), , , and Mantelatto et al (2004). Among the studies treating other parts of the Brazilian coast are those of Souza (1997) off Rio Grande do Sul and Lavrado et al (2000) in Guanabara Bay, Rio de Janeiro.…”

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.Key words: Composition, Biodiversity, Brachyura. ResumoO objetivo do presente estudo foi caracterizar a composição e a abundância dos caranguejos no infralitoral não-consolidado de duas regiões (Ubatuba e Caraguatatuba) do litoral norte paulista, Brasil. Em cada região foram realizadas coletas mensais em sete profundidades, durante o período de dois anos (Julho/ 2001 a Junho/ 2003), utilizando-se um barco de pesca equipado com duas redes do tipo "double-rig". Obteve-se um total de 30.231 caranguejos (13.305 em Ubatuba e 16.926 em Caraguatatuba), abrangendo nove superfamílias (Dromioidea, Homoloidea, Calappoidea, Leucosioidea, Majoidea, Parthenopoidea, Portunoidea, Xanthoidea e Pinnotheroidea), 16 famílias, 29 gêneros e 44 espécies. Do total de espécies coletadas, 31 foram comuns para as duas regiões. Dentre as duas regiões, Caraguatatuba apresentou a maior riqueza de espécies (42)

The present study provided information extending the known geographical distribution of three species of majoid crabs, the epialtids Acanthonyx dissimulatus Coelho, 1993, Epialtus bituberculatus H. Milne Edwards, 1834, and E. brasiliensis Dana, 1852. Specimens of both genera from different carcinological collections were studied by comparing morphological characters. We provide new data that extends the geographical distributions of E. bituberculatus to the coast of the states of Paraná and Santa Catarina (Brazil), and offer new records from Belize and Costa Rica. Epialtus brasiliensis is recorded for the first time in the state of Rio Grande do Sul (Brazil), and A. dissimulatus is reported from Quintana Roo, Mexico. The distribution of A. dissimulatus, previously known as endemic to Brazil, has a gap between the states of Espírito Santo and Rio de Janeiro. However, this restricted southern distribution is herein amplified by the Mexican specimens.
