O REGISTRO MAIS AO NORTE DO BRASIL DO CARANGUEJO DE CORAL Carpilius corallinus (HERBST, 1783) (DECAPODA: CARPILIIDAE) COLETADO COMO FAUNA ACOMPANHANTE NO GRANDE SISTEMA DE RECIFES AMAZÔNICOS

The coral crab Carpilius corallinus (Herbst, 1783) is popularly known in Brazil as “Guajá”, which is widely distributed in tropical marine areas, associated with coral reefs in costal zones. C. coralinus occurs in Brazilian waters with disjoint distribution, covering the States from Ceará to Alagoas, with specific records in States of Bahia, São Paulo, Fernando de Noronha Archipelago and Rocas Atoll. Here, we report the northernmost record of C. coralinus, from State of Pará with its occurrence on Great Amazon Reef System (GARS). Was collected one male specimen as bycatch in artisanal fisheries on Amazon River Mouth (01°24'55.008"N; 046°39'58.86"W) at depth of 76.2 m. This record fills the gap on distribution of C. coralinus in Brazil, and increase number of crabs species occurring in Great Amazon Reef System (Pará).Keywords: Amazon River Mouth; Coral associated crab; North coast; State of Pará; Artisanal Fisheries.O caranguejo de coral Carpilius corallinus (Herbst, 1783) é popularmente conhecido no Brasil como “Guajá”, o qual é amplamente distribuído em áreas marinhas tropicais, associados com recifes de corais em zonas costeiras.

REGISTRO DA LAGOSTA SAPATEIRA Scyllarides brasiliensis RATHBUN, 1906 (DECÁPODA: SCYLLARIDAE) NO GRANDE SISTEMA DE RECIFES AMAZÔNICOS, PARÁ, BRASIL

The slipper lobster Scyllarides brasiliensis Rathbun, 1906 (Scyllaridae Latreille, 1825) has a broad distribution in Western Atlantic, however with disjoint records in costal zones between 20 and 40 m, associated in bottoms of gravel and coral reefs. From Brazilian waters, this species has been recorded from States of Maranhão to Bahia and with sporadic records in States of São Paulo and Santa Catarina. Based on that, herein we report the northernmost record of S. brasiliensis in Brazil and its first observation from the Amazon Reef System (ARS). A male specimen was collected through the lobster fishing boat (commercial fishing) in State of Pará (01°23’53.952” N; 046°40’46.452” W) at the depth of 76.2 m. This new record increases the geographic distribution of S. brasiliensis from State of Pará (Brazil) and expands the knowledge of the crustacean biodiversity in the Amazon Reefs.Keywords: Amazon River Mouth; Bycatch, Lobster; Northernmost Record; Scyllaridae.A lagosta sapateira Scyllarides brasiliensis Rathbun, 1906 (Scyllaridae Latreille, 1825) possui uma ampla distribuição no Oeste do Atlântico, com distribuição disjunta em zonas costeiras entre 20 e 40 m, onde se encontra associada a fundos de cascalho e recifes de corais. Em águas Brasileiras, essa espécie tem sido registrada dos Estados do Maranhão à Bahia e com registros esporádicos nos Estados de São Paulo e Santa Catarina. Baseado nisso, aqui nos reportamos o registro mais ao norte de S. brasiliensis no Brasil e sua primeira observação para o Sistema de Recifes Amazônicos (SRA).

Community ecology, taxonomy and geographic distribution of the deep-sea shrimps in northeastern Brazil

The Potiguar Basin was formed in mesocenozoic age occurring between the States of Ceará and Rio Grande do Norte, being target of several cientific researches, especially by environmental agencies promoved by private initiative and public agents, due its great biological wealth and mineralogical in this region. However in Potiguar Basin, the environmental studies are being focused especially in costal zones, thus making deep-sea aspects nonexistent along the continental slope (> 200 m) still unknown, principally in aspects about the deep invertebrate biodiversity.Similar aspects about the little knowledge of the deep invertebrate biodiversity are observed for the regions of oceanic Islands, as for exemple, in Fernando de Noronha Archipelago, Atoll as Rocas Atoll and seamounts as those registered in North Ceará Chain. Due to this, this theses has as objective analyse the community structure of the deep-sea shrimps occurring in Potigar basin and report the taxonomic composition and distributional aspects of deep-sea shrimps in Potiguar Basin, oceanic Islands and seamounts in the Brazilian Northwestern region.The samples were collected in two different areas. First in the Potiguar Basin, located in the northeast of Brazil between (03/05° S; 38/35° W), in the states of Ceará (CE) and Rio Grande do Norte (RN), under the framework ofthe project “Avaliação da biota bentônica e plânctonica da Bacia Potiguar e Ceará (Bpot)”, on board theR/V Luke Thomas in 2009 and by R/V Seward Johnson in May 2011, with bottom trawls conducted on the continental slope using a semi-balloon otter trawl with 50 mm of mesh size and 18 m of mouth opening, between the isobaths of 150, 400, 1000 and 2000 m. After, samples collected during the framework of project ABRAÇOS (Acoustic along the Brazilian coast), on Fernando de Noronha Archipelago, Rocas Atoll and Seamounts in Ceará Chain, which occurred in October 2015 and April of 2017, through the water column by using the drag of a micronekton net with 1 mm of mesh, with stations (#ST) between 10–1660 m depth. From Potiguar Basin, were collected 49 species, being represented by 15 families, while in oceanic islands were sampled 27 species belonging to 5 families. For the Potiguar Basin, the distribution of the shrimps showed associated with the water mass, being the abiotic factos dodominant in vertical distribution. The high indices of richness ware observed in depth of 400 and 1000 m, and the low values being associated with deeper water mass. The highest peaks of diversity were observed at depth of 1000 m, with the deeper stations showing the lower values. Along the analysis of community, were observed species descriptors of water mass, which are restrict only abiotic factors action in each depth. The informations showed herein; highlight the first observations about the aspects thar governing the deep-sea shrimps community occurring in Potiguar basin, beyond of the taxonomic composition and distributional aspects of this deep fauna

Further Record of the Deep-Sea Euphausiid, Thysanopoda Cristata G. O. Sars, 1883 (euphausiacea, Euphausiidae) from the Southwestern Atlantic: With Comments on Morphological Variations

Place: Leiden Publisher: Brill WOS:000776485200002International audienceEuphausiids are a diverse order of crustaceans that play a key role in pelagic food webs. The genus Thysanopoda H. Milne Edwards, 1830 is composed of 14 valid species, widely distributed in all oceans. However, some gaps remain in our knowledge of the geographic distribution of Thysanopoda cristata G. O. Sars, 1883, and its actual occurrence in Brazil. This study aims to expand the knowledge on krill diversity in Brazilian waters, confirming the occurrence of T. cristata and providing illustrations of its morphological variations. Four specimens, two males and two females, were collected on board R/V "Antea" in October 2015, using a micronekton net with 1 mm mesh size, at depths ranging between 10 and 1660 m. Before this study, reports of T. cristata from Brazil were provided only in species lists or unpublished data. Our study confirms the presence of the species from the southwestern Atlantic and brings new information on its morphology

New records and bathymetric distribution of deep-sea shrimps of the family Glyphocrangonidae (Decapoda: Caridea) from the Potiguar Basin, northeastern Brazil

Abstract The caridean family Glyphocrangonidae Smith, 1884 is monotypic, including only the genus Glyphocrangon A. Milne-Edwards, 1881. The species of this genus are exclusively inhabitants of deep sea. The current contribution aims to enrich the knowledge of Glyphocrangon in the southwestern Atlantic, by reporting its occurrence and bathymetric distribution in the Potiguar Basin, northeastern Brazil. The samples were collected by R/V Luke Thomas and R/V Seward Johnson, with bottom trawling at isobaths of 400, 1,000 and 2,000 m, using an otter trawl semi-balloon. The specimens were identified and stored in the carcinological collection of the Museu de Oceanografia Prof. Petrônio Alves Coelho, in Recife, Brazil. A total of 810 specimens were examined from five species: Glyphocrangon aculeata A. Milne-Edwards, 1881, G. alispina Chace, 1939, G. longirostris (Smith, 1882), G. sculpta (Smith, 1882) and G. spinicauda A. Milne-Edwards, 1881. Glyphocrangon spinicauda was the most abundant with 334 individuals, and G. sculpta was the rarest, with only one individual. All species were recorded in the study area for the first time
