Cryptogenic Species

Bioeroding sponges of theCliona viridisspecies complex play a large role in carbonate cycling and reef health. In the present study we provide the first record and a description of a Mediterranean lineage ofC. viridis(Schmidt, 1862) in the south-western Atlantic. Specimens were collected in Maricás Archipelago, Rio de Janeiro State in September 2010 by scuba diving at 10–12 m depth and deposited in the Porifera collection of Museu Nacional, Universidade Federal do Rio de Janeiro. Morphologically, the specimens presently examined are very similar to those described in the beta and gamma growth form from the Mediterranean. The Brazilian and Mediterranean specimens share large and irregular papillae over 2 cm in diameter, megasclere tylostyles up to 500 µm long and microsclere spirasters with up to five twists and 34 µm long. A Maximum Likelihood analysis of 28S rDNA ofC. viridis, C. aprica, C. jullieni, C. schmidtiandC. varianswas performed for a genetic identification of the Brazilian specimens. The Brazilian material is phylogenetically closer to the MediterraneanC. viridisthan to the Caribbean and Indian Ocean members of this species complex included in the present analysis. Our results suggest thatC. viridisis a cryptogenic species with a distribution extending from the Mediterranean to the eastern Atlantic and in the SE Brazilian coast or further.

Unknown Species

Despite the increasing number of reports on the deep-sea molluscs from the south-western Atlantic, we know very little about the protobranchs. The lack of information on the protobranch Pelecypoda off southern Brazil is reflected in the genusYoldiella. This contribution is part of an effort to increase the knowledge about this group off the Brazilian coast. Eight species ofYoldiellaare recognized here. ForYoldiella biguttata, previously reported from Brazil, the known distribution is extended southwards to the Campos Basin. ForYoldiella similisthis is the first record in the western Atlantic Ocean. ForYoldiella extensaandYoldiellaaff.jeffreysithis is the first record for Brazil. Four previously unknown species are described,Yoldiella lapernoisp. nov.,Yoldiella paranapuaensissp. nov.,Yoldiella arariboiasp. nov. andYoldiella curupirasp. nov. Considering only conchological features for the Atlantic species we could propose some clusters of species ofYoldiella.

Recent studies reported the introduction of non-native species on the Brazilian coast. In this contribution, we provide the first record of Cephalopholis taeniops (Valenciennes 1828) in the western South Atlantic, based on a specimen captured off the Ilhas Cagarras, Rio de Janeiro, Brazil, and discuss the potential agents for its introduction. While this single specimen was collected in 2006 in a well-known locality, no other specimen has been captured since.

AbstractIn this study we report the first finding of the red alga Acanthosiphonia echinata in the Mediterranean Sea. Specimens were identified using the DNA barcoding method and, in particular, the plastidial rbcL and the mitochondrial COI-5P markers. This species has been considered to be restricted to the western Atlantic and was reported in blooms from North Carolina to South Carolina. In 2015 the introduction of this species in Southeast Asia (Indonesia) was reported. Probably this taxon was introduced in the Mediterranean Sea from Indonesian populations associated with seaweed farming activities or hull fouling, via the western Atlantic-Mediterranean-Indonesia ship route.

Reef Fish Community

Reef fish community structures at three sites in the state of Rio de Janeiro (Pedra Vermelha (PV), Cabo Frio Island—Arraial do Cabo; Mãe Island (MI), Itaipu—Niterói; Comprida Island (CI), Cagarras Archipelago—Rio de Janeiro) were investigated to assess differences in fish species composition, density and distribution of trophic groups, between sites, correlating the observed patterns of fish distribution with environmental factors. Thirty-six visual strip-transects yielded 67 species of 34 families. Studied locations shared at least 40% of all species, mostly of western Atlantic distribution. The three sites presented significant differences on diversity, density and species dominance. CI presented the highest values, except for total density, which was higher at PV, probably due to its partial degree of protection. MI showed the lowest values, suggesting possible impacts from the proximity to the shore. The main trophic categories were omnivores followed by mobile invertebrate feeders, in similarity to what was previously observed for south-eastern Brazil. Inherent habitat features of each location regarding depth, declivity, visibility and rugosity resulted in different species distribution and dominance patterns.

ABSTRACT The occurrence of hyperostotic bones is common in marine fish, especially in the Carangidae family, despite few records of this condition in fishes from Brazilian waters. The present study describes the occurrence of hyperostosis in Atlantic moonfish (Selene setapinnis) in, Rio de Janeiro State, Brazil. Radiographs of the fish specimens were taken and all of them presented hyperostosis in at least three different regions: cleithrum, pterygiophores and pleural ribs. The observed pattern is different from previously described for other species of the same genus. It is the first record for the species and a valuable contribution to the study of bone diseases in fishes from the Brazilian coast.

Hexactinellid Sponges

Descriptions of hexactinellid sponges collected by the RV ‘Marion Dufresne’ MD55 expedition on the Vitória–Trindade seamounts chain (off Espírito Santo State, south-eastern Brazil) in 1987 and stored in the MNHN (Muséum National d'Histoire Naturelle in Paris) are presented. Hyalonema (Cyliconema) conqueror sp. nov. (the first finding of this subgenus in the Atlantic Ocean) and H. (Prionema) dufresnei sp. nov. (the second record of this subgenus for the Atlantic Ocean) are described as new species. The holotype of H. (C.) conqueror sp. nov. was collected with a ROV at Campos Basin (off Rio de Janeiro State, south-eastern Brazil), while the paratypes originated from Vitória–Trindade seamounts chain and off Bahía State (eastern Brazil). Other hexactinellids reported here, Farrea sp., Sarostegia aff. oculata, Aphrocallistes aff. beatrix, Dactylocalyx aff. subglobosus and Euplectella suberea were known before to be widely distributed in the Atlantic Ocean. The total number of hexactinellid sponges known from Brazil has risen to 15 and from the south-western Atlantic to 23.

Morphological And Molecular Data

The genus Pseudoboletia was recently reported off coast of Brazil (Trindade-Martin Vaz insular complex). This study reports the first record of this genus to southern of Brazil in Rio de Janeiro and Santa Catarina coasts. Morphological and molecular data showed that sea urchins from Brazil and São Tomé are the same species, genetically distinct of individuals from Indo-Pacific. However, taxonomic identity of Brazilian species remains as a challenge. Two hypotheses to explain the recent records of this species on Brazilian coast are discussed: a recent natural invasion by long-distance dispersal and a recent population expansion in the Brazilian coast after absence or low density period.

New arcid species belonging to the genera Paranadara gen. nov., Acar and Asperarca (new record) are described for the western Atlantic Ocean based on shell morphology. Paranadara taludae sp. nov., Acar naturezae sp nov., Acar oliveirae sp. nov. and Asperarca tarcylae sp. nov. were collected off north-eastern Brazil between depths of 70 and 690 m, whereas Acar lepidoformis sp. nov. was dredged off the State of Rio Grande do Sul (southern Brazil) at a depth of 141 m. There are no species along the Brazilian coast that are morphologically similar to Paranadara taludae sp. nov. Acar naturezae sp. nov., Acar lepidoformis and Acar Acar oliveirae sp. nov. are similar to this genus due to shape, ligament, presence of concentric lamellae cut by radial threads, a broad dorsal area and a markedly narrowed anterior region in comparison to the posterior region, which is strongly expanded. Asperarca tarcylae sp. nov. is similar to this genus due to the presence of a small edentulous region below the umbo and smooth inner margin.
