Desarrollo larval de Mursia gaudichaudi (Milne Edwards 1837) (Decapoda, Brachyura, Calappidae)
Provedor de dados: 72
Autores: Gallardo,María de los A; Mujica,Armando.
Se describe el desarrollo larval de Mursia gaudichaudi basado en las zoeas I y II cultivadas en laboratorio y las zoeas I a la IV obtenidas de muestras planctónicas. Las larvas cultivadas en laboratorio, se obtuvieron de hembras ovígeras capturadas en la costa de Coquimbo, norte de Chile. Las características morfológicas y morfométricas de éstas permitieron identifcar las larvas capturadas con redes de plancton en la zona de Caldera y Coquimbo, durante la primavera de 2005. Las espínulas en la región proximal de la espina rostral, las de las espinas laterales del cefalotórax, los procesos espinosos de la antena y la longitud e inserción de las espinas laterales del abdomen, son las principales características morfológicas y morfométricas que permiten...

Fecundity of the spider crab Mithraculus forceps (Decapoda, Mithracidae) from the northeastern coast of the state of São Paulo, Brazil
Provedor de dados: 76
Autores: Cobo,Valter J.; Okamori,Claudia M.
Fecundity is one of the most important parameters in studying the reproductive output of Pleocyemata decapods, especially because of its relationship to the efficiency of population replacement. Knowledge of fecundity provides basic elements for understanding the reproductive strategies, dynamics, and evolution of a given population. The present investigation provides informations on fecundity, egg size, egg loss, and the relationship between fecundity and selected environmental features, for the spider crab Mithraculus forceps (A. Milne Edwards, 1875). Ovigerous crabs were collected each month during 2000, by SCUBA diving, at Couves Island (23º25'25"S, 44º52'03"W) on the northeastern coast of the state of São Paulo, Brazil. A total of 40 ovigerous females...

Evaluation of the stomach contents of Eriphia gonagra from a rocky shore in the southeastern Brazilian coast
Provedor de dados: 76
Autores: Rodrigues,Larissa R.; Góes,João M. de; Silva,Thiago E. da; Teixeira,Gustavo M.; Andrade,Luciana S. de; Fransozo,Adilson.
ABSTRACT The rocky shores of Praia Grande, in Ubatuba (São Paulo, Brazil), are formed by rock and Sabellaridae polychaete sandy reefs. These microenvironments offer shelters and foraging areas for several marine organisms and attracts many tourists. The crab Eriphia gonagra (Fabricius, 1781) inhabits these structures and can be used as a bioindicator, since they may be affected by anthropogenic actions. This study evaluated the stomach contents and characterized the feeding habits of an E. gonagra population, inhabiting the rocky shores from Praia Grande, taking into account the sex, size, and microhabitat. Monthly samplings were performed in 1996 and 1997 and the crabs were manually captured on the rocky surface or into of the sand reefs. So, the...

Estructura del aparato reproductor masculino de Uca uruguayensis (Decapoda, Ocypodidae)
Provedor de dados: 76
Autores: Cuartas,Elena Irene; Petriella,Ana María.
The structure of the male reproductive tract was described in Uca uruguayensis Nobili, 1901, by using histological methods, scanning electron microscopy techniques, and stereoscopic observations of fresh material. The aim of this work was to establish the functional changes associated with sexual maturation. The morphology of the first (G1) and second (G2) pair of gonopods was described. The male reproductive tract consists of paired organs: testes, and tubular and convoluted vas deferens (VD) ending with a terminal ampoule (TA).The (VD) is composed of three parts: anterior (AVD), medial (MVD) and posterior (PVD). The AVD and MVD are lined by a single layer of cubical cells. The PVD epithelial cells are columnar with elongated nuclei. The terminal ampoule...

Autores: Ahyong, Shane T.; Ng, Peter K. L.
The cyclodorippoid crabs from the Philippines collected by the PANGLAO 2004-2005 and AURORA 2007 expeditions are reported. Five species of Cyclodorippidae are reported: Corycodus mina x sp. nov., Ketamia depressa (Ihle, 1916), Krangalangia spinosa (Zarenkov, 1970), Tymolus brucei Tavares, 1991, and Xeinostoma sakaii Tavares, 1993. Corycodus minax is the second species of the genus to be recorded from the Philippines and is most similar to C. merweae Tavares, 1993, from South Africa. Krangalangia spinosa is reported for the first time from the Philippines. Sexual dimorphism in the length of the walking legs (pereopods 2 and 3) is reported for Tymolus brucei and may be a general feature of cyclodorippoids. One new species of Cymonomidae, Cymonomus liui sp....

Spatial and temporal distribution of brachyuran crab larvae in Ibiraquera Lagoon, southern Brazil
Provedor de dados: 5
Autores: Brandão, Manoela; Stumpf, Liane; Macedo-soares, Luis; Freire, Andrea.
This study investigated the abundance and composition of brachyuran crab larvae in the four subsystems of Ibiraquera Lagoon throughout the year. A colder and drier period was detected, contrasting with warm months during which salinity varied depending on rainfall and whether the sand bar was open or closed. The mean density of brachyuran zoeae was 540 ± 96 (SE) larvae · 100 m-3. Mean density was significantly (p&lt;0.05) higher in three subsystems during April. Saco Lagoon (the outer subsystem) exhibited significantly higher (p&lt;0.05) mean density in July, August, October, November and December 2004. Larvae from the families Portunidae, Menippidae, Panopeidae, Ocypodidae and Varunidae were found in Ibiraquera Lagoon. Neohelice granulata Dana, 1851 was...

Re-evaluation of the Cancridae Latreille, 1802 (Decapoda: Brachyura) including three new genera and three new species
Provedor de dados: 16
Autores: Schweitzer, Carrie E.; Feldmann, Rodney M.
New fossils referable to the Cancridae Latreille, 1802 extend the known stratigraphic range of the family into the middle Eocene and the geographic range into South America. Each genus within the family has been reevaluated within the context of the new material. A suite of diagnostic characters for each cancrid genus makes it possible to assign both extant and fossil specimens to genera and the two cancrid subfamilies, the Cancrinae Latreille, 1802, and Lobocarcininae Beurlen, 1930, based solely upon dorsal carapace morphology. Cheliped morphology is useful in assigning genera to the family but is significantly less useful at the subfamily and generic level. Each of the four subgenera sensu Nations (1975), Cancer Linnaeus, 1758, Glebocarcinus Nations,...

Platypodiella georgei spec. nov. (Brachyura: Xanthidae), a new crab from the island of St. Helena, South Atlantic Ocean, with notes on the genus Platypodiella Guinot, 1967
Provedor de dados: 16
Autores: Hartog, J.C. den; Türkay, M.
A new species of Platypodiella Guinot, 1967, from the island of St. Helena, P. georgei spec, nov., is described. This species was found associated with encrusting species of Palythoa Lamouroux, 1816 (Zoantharia). Ample evidence is presented that both the eastern Atlantic P. picta (A. Milne-Edwards, 1869) and the western Atlantic P. spectabilis (Herbst, 1794) also live habitually associated with encrusting species of Palythoa, rarely with other zoantharians. For each of the two East-Pacific members of the genus, P. rotundata (Stimpson, 1860) and P. gemmata (Rathbun, 1902), there is at least one rather detailed published record suggesting that these species too associate with Palythoa. Thus, this habit would seem to go for all five members of the genus. Data...

Provedor de dados: 16
Autores: Busulini, A.; Beschin, C.; Tessier, G.
A reassessment of extinct species, fourteen in all, found in Europe and attributed to Calappilia has been carried out. For each species a short diagnosis is provided, and where necessary, its systematic position is reconsidered. Calappilia dacica lyrata is here elevated to species rank, while C. mainii is reassigned to Stenodromia A. Milne Edwards in Bouillé, 1873 and C. sexdentata is considered to be a nomen nudum. Photographs are provided of all type specimens available to us; most of these had so far been known only from (partially inaccurate) line drawings. For the first time, well-preserved chelipeds are described for the genus, having been found in articulation with a carapace of C. dacica.

Provedor de dados: 16
Autores: Rahayu, D.L.; Ng, P.K.L.
Two new species of sesarmid crabs are described from the mangroves of Timika in Papua (= Irian Jaya), Indonesia. Haberma kamora spec. nov. is the second species in the genus described from Singapore, differing from the type species in the form of its male first pleopods and possessing relatively more slender ambulatory legs. Parasesarma charis spec. nov. resembles P. erythrodactyla, P. tripectinis and to some extent, P. lepidum, but has different ambulatory leg proportions and a distinctive male first pleopod structure. Parasesarma acis Davie, 1993, is regarded as a junior synonym of P. tripectinis Shen, 1940.

A revision of the genus Matuta Weber, 1795 (Crustacea: Brachyura: Calappidae)
Provedor de dados: 16
Autores: Galil, B.S.; Clark, P.F.
Introduction Amid the gaudily-coloured parade of tropical crabs few are more splendidly patterned than the matutine genera. But the patterns decorating these species brought about taxonomic disarray and from the very beginning they baffled their researchers. Already in 1817 Leach remarked: "the characters which distinguish the species are very obscure". MacLeay (1838) wrote in exasperation: "there are many species confounded together under the name Matuta victor, I do not consider the above names of the family and genus to possess any authority". Stebbing (1905) concurred: "From the interminable discussion of minute differences, as to the importance of which distinguished authors neither agree one with another nor always with themselves, it seems safe to...

Evolution of crabs – history and deconstruction of a prime example of convergence
Provedor de dados: 16
Autores: Scholtz, G.
Compared with the elongate bodies of shrimps or lobsters, crabs are characterised by a compact body organisation with a depressed, short carapace and a ventrally folded pleon. The evolutionary transformation from a lobster-like crustacean towards a crab is called ‘carcinization’ and has been interpreted as a dramatic morphological change. Nevertheless, the crab-shape evolved convergently in a number of lineages within Decapoda. Accordingly, numerous hypotheses about internal and external factors have been presented, which all try to explain these frequent convergent carcinization events despite the seemingly fundamental changes in the body organisation. However, what a crab is lies greatly in the eye of the beholder and most of the hypotheses about the...

Progress on the fossil Xanthoidea MacLeay, 1838 (Decapoda, Brachyura)
Provedor de dados: 16
Autores: Schweitzer, Carrie E.
Identification and utilization of proxy characters in extant families has been accomplished with success for fossil members of the Calappidae, Hepatidae, Necrocarcinidae, Matutidae, and Hexapodidae. The fossil and extant Raninidae have been revised using primarily hard-part morphology preserved in the fossil record although formal designation of “proxy characters” has not occurred. Hard-part characters can also be used to differentiate among members of the Atelecyclidae and the Cheiragonidae. Thus, the method of using proxy characters is demonstrably suitable for application to a difficult group like the Xanthoidea.

A new classification of the Xanthoidea sensu lato (Crustacea: Decapoda: Brachyura) based on phylogenetic analysis and traditional systematics and evaluation of all fossil Xanthoidea sensu lato
Provedor de dados: 16
Autores: Karasawa, H.; Schweitzer, C.E.
A phylogenetic analysis was conducted including representatives from all recognized extant and extinct families of the Xanthoidea sensu lato, resulting in one new family, Hypothalassiidae. Four xanthoid families are elevated to superfamily status, resulting in Carpilioidea, Pilumnoidoidea, Eriphioidea, Progeryonoidea, and Goneplacoidea, and numerous subfamilies are elevated to family status. The Mathildellidae is moved from the Goneplacidae to the Portunoidea. Diagnoses for all superfamilies and families discussed herein are provided, embracing characters typically used by biologists as well as readily fossilized features of the dorsal carapace, sternum, abdomen, and chelipeds. All genera known from the fossil record at one time referred to the Xanthidae...

Autores: Jagt, J.W.M.; Fraaije, R.H.B.; Bakel, B.W.M.  van.
Strata of latest Cretaceous (late Maastrichtian) and earliest Paleogene (early Paleocene) age in the (extended) type area of the Maastrichtian Stage are comparatively rich in decapod crustaceans. Particularly common are chelae of the callianassoid Mesostylus faujasi (Desmarest, 1822), followed by carapaces of various species of necrocarcinid and raninid, plus the ?longusorbiid Binkhorstia ubaghsii (van Binkhorst, 1857) and chelae of paguroids; other taxa are much rarer. Recently collected material, all stratigraphically well constrained, has enabled us to reinterpret, and reassign, a number of species. Specimens contained in old museum collections have proved indispensable in that respect. Undescribed taxa have also come to light; here a new dromioid,...

The Dakoticancridae (Decapoda, Brachyura) from the Late Cretaceous of North America and Mexico
Provedor de dados: 16
Autores: Bishop, G.A.; Feldmann, R.M.; Vega, F.
The podotrematous crab family Dakoticancridae includes four genera: Dakoticancer Rathbun, Tetracarcinus Weller, Avitelmessus Rathbun, and Seorsus Bishop, all known solely from the Late Cretaceous of North America. Lathelicocarcinus Bishop, originally referred to the family, must be reassigned. Fine details of anatomy, preserved on specimens of D. overanus Rathbun and A. grapsoideus Rathbun, permit description of genital openings and interpretation of functional morphology of appendages. Although one species, D. australis Rathbun, has been found associated with burrow structures, all were probably vagrant epifaunal animals on fine- to medium-grained siliciclastic substrata. Food was probably obtained by generalized low-level predation and scavenging....

Ovigerous females of Arenaeus cribrarius were collected at Ubatuba, São Paulo, and maintaining in aquaria under controlled temperature (25±1ºC), salinity (35±1‰) and photoperiod (12:12). A small sample of eggs was collected for each 24h, for morphological description, chromatic changes and biometric analysis throughout the embryonic development. Eight egg stages were photographed and had their small and large diameters measured under a microscope provided with camera lucida. The egg's shape was low elliptical during all the embryogenesis and showed size increase (24.4%) and volume (91.1 %), when the last stage were compared with the first one. According to mean egg diameter and volume, the eggs should be pooled in three different groups (1-3; 4-6; 7-8)...

Investigations of the distribution of marine organisms provide a better understanding of the patterns of distribution and dispersal of these animals. Extensions of the distributional limits of decapod crustaceans in Brazilian waters have been recorded steadily and gradually, but these limits still remain poorly understood. The present study provides information extending the known range of eight species of brachyuran crabs and one species of porcellanid crab. The animals were obtained by Scuba diving during a sampling program carried out near Vitória Island, Ilhabela, on the northeastern coast of the State of São Paulo (23º44'04"S-45º01'35"W) between February, 2004 and January, 2005.

Some individuals of the species Arenaeus cribrarius (Lamarck, 1818) bear a characteristic pink abdomen, which is notably different from the usual white coloration. The incidence of this chromatic alteration was determined for a single population and its relation with other individual variables were examined. The individuals were monthly collected from May, 1991 to April, 1993, in Ubatuba, São Paulo, with the aid of a shrimp fishery boat provided with double-rig trawling nets. All specimens were sexed, measured (CW = carapace width), distributed in 10-mm size classes and classified according to growth phase (juvenile and adult), molting condition and development stage of gonads. The occurrence of pink-colored morphs was also recorded. From a total of 2,096...

Several families were added in the past in order to constitute the Xanthidae, but the boundaries between Xanthidae, Parthenopidae and Goneplacidae were diluted, and the classification of some genera doubtful. By this reason was made the analysis of a typical genus of each subfamily occurring in Brazil. 50 characters were selected and coded as (0) for absence and (1) for presence. The data matrix was analysed by computer programs NTSYS and NMIX. The phenetic analysis shows the Xanthidae as a good family, but the cladistic one (Wagner tree) split them in four families: Carpiliidae, Xanthidae (with the subfamilies Menippinae, Platyxanthinae, Xanthinae and Eucratopsinae), Eriphiidae and Pilumnidae (with the subfamilies Trapeziinae and Pilumninae)....

Associations between jellyfish and other organisms are frequently reported. Neverhteless, few of those records include crabs inhabiting medusae. Lychnorhiza lucerna Haeckel, 1888 were sampled (n = 1988) on the coast of the State of Paraná (25º20'-25º55'S, 48º10'-48º35'W), southern Brazil, from December 1997 to December 2004. Eight percent (166 individuals) of the medusae had one spider crab Libinia ferreirae Brito Capello, 1871 living within its subgenital porticus or on the oral arms. Megalopal stages of the same crab were also found on three jellyfish. All crabs associated with L. lucerna were young and smaller (&lt; 3 cm) than solitary crabs caught on the bottom. Thus, L. ferreirae probably colonizes the jellyfish as a late larva and uses it as a...

Autores: WATANABE,TIMOTEO T.; ZARA,FERNANDO J.; HATTORI,GUSTAVO Y.; TURRA,ALEXANDER; SANT'ANNA,BRUNO S.
A marine biological invasion is a natural process accelerated by human activities, and the crab Charybdis hellerii is an example of a globally widespread invasive species. This study evaluated color variation in C. hellerii and its relationship to the sex, size and sexual maturity of these crabs, and compared the efficiency of a freeware digital image-editing program with a commercially available program. The color of the individuals was analyzed using standardized digital images. The color pattern varied significantly with size; smaller and immature individuals were darker than larger and mature ones. The female abdomen changed in morphology and color with sexual maturity, becoming wider and orange-colored. There was no statistical difference in the color...

The distribution of the freshwater crab Fredius reflexifrons (Ortmann, 1897) (Brachyura, Pseudothelphusidae) in an Environmental Protection Area of the Planalto da Ibiapaba, Northeastern Brazil
Provedor de dados: 42
Autores: SANTOS,LIVANIO C. DOS; NASCIMENTO,WHANDENSON M. DO; MATOS,HELAINE S.; PINHEIRO,ALLYSSON P.; SILVA,JOSÉ R.F.
Abstract  Freshwater crabs are important components of aquatic ecosystems; however, their distributions are restricted because of characteristics of their life history, which hinder conservation strategies. Fredius reflexifrons is a widely distributed freshwater crab of the Amazon basin with relictual occurrences in small wetlands on the Planalto da Ibiapaba in Northeastern Brazil. Habitat degradation, destruction of forest patches, channeling of water bodies, and the use of land for legume cropping can seriously impact the species by leading to the extinction of its relic populations, which have limited distributions in the Área de Proteção Ambiental (APA; Environmental Protection Area) Bica do Ipu of the Planalto da Ibiapaba. The objectives of this study...

Provedor de dados: 42
Autores: Araújo,Marina S.L.C.; Barreto,Aline V.; Negromonte,Aurinete O.; Schwamborn,Ralf.
This paper aims at describing the population ecology of the swimming crab Callinectes danae Smith, 1869 in one of the most productive estuaries of Brazil, the Santa Cruz Channel. These crabs were monthly collected from January to December/2009 at four stations along the channel, two in the upper and two in the lower estuary. A total of 2373 specimens of C. danae were collected during the study. Males had a larger average carapace width than non-ovigerous females (60.0 ± 15.6 mm and 52.9 ± 12.4 mm, respectively), an adaptation that gives greater protection for females during the copulation. Overall sex ratio did not differ significantly from 1:1. However, evaluating sex-ratio by sampling area, males and juveniles of both sexes occurred preferentially in the...

Reproduction and management of the mangrove crab Ucides cordatus (Crustacea, Brachyura, Ucididae) at Iguape, São Paulo, Brazil
Provedor de dados: 42
Autores: SANT'ANNA,BRUNO S.; BORGES,ROBERTO P.; HATTORI,GUSTAVO Y.; PINHEIRO,MARCELO A. A.
The mangrove crab Ucides cordatus is one of the most exploited crustaceans in Brazil. The present study investigated the breeding season of this species and the period of the “andada” phenomenon, when the crabs are active outside their burrows and perform agonistic behaviors. Furthermore related them to environmental factors, in a mangrove on the coast of Brazil, with inferences about management of this crab. The crabs reproduced from October through February. The “andada” occurred from November through February, with typical characteristics in the first two months, during the full and new moon periods, and was influenced positively by the air and soil temperature, luminosity, and tidal amplitude, and negatively by salinity. Based on the results of the...

Spatial and temporal distribution and abundance of two species of Persephona (Decapoda: Brachyura: Leucosiidae) on the southern coast of the state of São Paulo, Brazil
Provedor de dados: 49
Autores: Perroca,Júlia Fernandes; Herrera,Daphine Ramiro; Costa,Rogerio Caetano da.
Abstract: Crabs of the genus Persephona are intensely captured in shrimp fisheries as bycatch in the Cananéia region off the coast of the state of São Paulo, Brazil. The analysis of the spatial and temporal distribution of Persephona punctata and Persephona mediterranea could provide information about variation in the abundance of these species, as well as the environmental variables affecting their distribution and the existence of a possible habitat partitioning. Using a shrimp fishery boat equipped with double-rig nets, crabs were monthly captured from July 2012 to June 2014 in seven sites: four in the coastal area adjacent to the Cananéia region and three in the Mar Pequeno estuarine area. The abundances of both species were compared according to...

ABSTRACT   We evaluated the incidental catch of the blue crab in artisanal fisheries through the analysis of sex ratio, catch per unit effort, net positioning, and size in which the capture probability was 50% (P50). The specimens were collected from 2011 to 2013 in the estuary of Patos Lagoon, southern Brazil. The analysis showed a higher occurrence of males. Variations in the catch per unit effort showed greatest abundance values close to the mouth of the estuary. Catch per unit effort was similar when comparing fishing seasons and net positions. P50 indicated a low selectivity of the nets since it varied between studied areas but stayed below the size at first maturity. Catches indicated a greater effort on males, since females migrated to spawn in the...

This study aimed to analyze the reproductive cycle of the crab Hepatus pudibundus (Herbst, 1785). The crabs were collected in Ubatuba, SP (23°26'S and 45°02'W) monthly from the July, 1992 to June, 1993. Samplings were performed with an "otter trawl". In the laboratory the crabs were numbered, sexed and measured for their maximum carapace width. The gonad developmental stage and the moult stage were also macroscopically registered. In all sampled months ovigerous females and crabs in both sexes with developed gonad were observed. Moult activity in all size classes was verified. Such fact indicates that this species can suffer moult process after their maturity. In despite of temperature being pointed a one of the most important ecological factor in the...
