“…Comparing the species found in the present study area (18°-23°S) with their incidence in other geographical regions studied by others authors along the Brazilian continental slope (Merlano & Hegedus, 1994;Sumida & Pires-Vanin, 1997;Miyaji, 2001;Scarabino, 2004) revealed some shared species. Nineteen species were shared between the present study and works done on the northeast region (11.37%), from a total of 167 species found.…”

“…In this study, we found high species turnover at station 16 (300 m depth), where some deep-sea species, such as Alvania xantias (Watson, 1885), Brookula spinulata (Absalão, Miyaji & Pimenta, 2001), and Solariella lubrica (Dall, 1881) showed a high dominance. Miyaji (2001) found a rough change, with 8% of sampled species occurring exclusively at depths greater than 400 m, whereas Sumida & Pires-Vanin (1997) found a different community from shallow areas occurring between 320 m and 500 m depth. Analyzing the vertical distribution of species found in this study (Table 2), we observed the occurrence of shallow-water and eurybathic species (shallowbathyal, distributions) at the slope stations.…”

ABSTRACT. Biogeographic distributional patterns of gastropods are proposed based on the species' geographic and bathymetric distribution. Samples were collected along the Brazilian continental margin between 18° S and 23° S, at 37 stations with depths from 20 m to 1,330 m. The analysis of the biogeographic distribution patterns confirmed the existence of a transitional zone from tropical to subtropical waters in the area of both the continental shelf and slope, suggesting a relationship with water mass circulation. We observed a high species turnover rate between the shelf and slope. The analysis of gastropod species distribution revealed a similar pattern on the shelf and slope and a large difference between shallow and deep-water faunas.

“…This region harbors a mixture of faunas originating from tropical, subtropical and subantarctic regions (Sumida & Pires-Vanin 1997). This was evident in the present study by the occurrence of Leurocyclus tuberculosus and Portunus spinicarpus, which occur more abundantly between Rio Grande do Sul in southern Brazil and Patagonia in Argentina (Pires 1992 andMelo 1996).…”

“…Sumida & Pires-Vanin (1997) reported that the changes in the benthic fauna of Ubatuba clearly follow the depth gradients, and are probably linked to the changes in the sediment and the physical stability of the water masses present in the region. Pires (1992) noted that between 10 and 40 meters depth, the predominant factor in the distribution of the fauna off Ubatuba is the type of sediment, which varies from silty to sandy; above 40 m, temperature is the principal factor responsible for structuring the communities.…”

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)

A commented list of Scaphopoda (Mollusca) found along the Brazilian coast, with two new synonymies in the genus Gadila Gray, 1847

This review aims to present an updated checklist of scaphopods, based mainly on literature database. There is a total of 40 species (six families) for Brazil, including information about the distribution and bathymetric range of each taxon. We propose two synonyms with the aid of morphometry of the shell, for the genus Gadila: G. longa as junior synonym of G. elongata and G. robusta as junior synonym of G. pandionis.
