It is referred to the family Septocrinidae Mironov, 2000, which now comprises three genera, Zeuctocrinus A.M. Clark, 1973, Septocrinus Mironov, 2000, and Rouxicrinus new genus. This new genus differs significantly from both Septocrinus and Zeuctocrinus in having numerous low columnals in the proxistele, which tapers toward the crown, first pinnule arising more proximally, thorns on brachials and pinnulars, and a thick covering of soft tissue on arms and pinnules. Key words: Rouxicrinus vestitus, Caribbean Sea, taxonomy, Crinoidea, Bourgueticrinida, Septocrinidae Introduction The family Septocrinidae is a small group of extant ten-armed sea lilies. The first-captured species of this group, Zeuctocrinus gisleni A.M. Clark, 1973, has been described in detail by A.M. Clark (1973), Roux (1977) and Roux et al. (2002). A.M. Clark (1973) referred Zeuctocrinus to the family Phrynocrinidae A.H. Clark 1907 comprising the extant Phrynocrinus nudus A.H. -

POMORY 2007 Department of Biology, University of West Florida, 11000 University Parkway, Pensacola, FL 32514, USA. [email protected] ABSTRACT A key is given for 85 species of ophiuroids from the Gulf of Mexico and Caribbean Sea covering a depth range from the intertidal down to 30 m. Figures highlighting important anatomical features associated with couplets in the key are provided. 2 INTRODUCTION The Caribbean region is one of the major coral reef zoogeographic provinces and a region of intensive human use of marine resources for tourism and fisheries (Aide and Grau, 2004). With the world-wide decline of coral reefs, and deterioration of shallow-water marine habitats in general, ecological and biodiversity studies have become more important than ever before (Bellwood et al., 2004). Ecological and biodiversity studies require identification of collected specimens, often by biologists not specializing in taxonomy, and therefore identification guides easily accessible to a diversity of biologists are necessary. -
Biodiversidad De Los Equinodermos (Echinodermata) Del Mar Profundo Mexicano
Biodiversidad de los equinodermos (Echinodermata) del mar profundo mexicano Francisco A. Solís-Marín,1 A. Laguarda-Figueras,1 A. Durán González,1 A.R. Vázquez-Bader,2 Adolfo Gracia2 Resumen Nuestro conocimiento de la diversidad del mar profundo en aguas mexicanas se limita a los escasos estudios existentes. El número de especies descritas es incipiente y los registros taxonómicos que existen provienen sobre todo de estudios realizados por ex- tranjeros y muy pocos por investigadores mexicanos, con los cuales es posible conjuntar algunas listas faunísticas. Es importante dar a conocer lo que se sabe hasta el momen- to sobre los equinodermos de las zonas profundas de México, información básica para diversos sectores en nuestro país, tales como los tomadores de decisiones y científicos interesados en el tema. México posee hasta el momento 643 especies de equinoder- mos reportadas en sus aguas territoriales, aproximadamente el 10% del total de las especies reportadas en todo el planeta (~7,000).

Nowadays, marine organisms are being given a lot of attention in drug discovery pipelines. In these studies, sponges and nudibranchs are frequently addressed, however an increasing number of * Corresponding author - DMP: [email protected] 2 David M. Pereira, Paula B. Andrade, Ricardo A. Pires, et al. works focus their attention in echinoderms. Given the fact that many of the bioactive molecules found in echinoderms are diet-derived, different feeding behavior and surrounding environment plays a critical role in the chemical composition of echinoderms. In this work, the most relevant chemical classes of small molecules present in echinoderms, such as fatty acids, carotenoids and sterols will be addressed. When data is available, the influence of the environment on the chemical profile of these organisms will be discussed. Keywords: Echinoderms; fatty acids; carotenoids; sterols. INTRODUCTION Marine environment remains, nowadays, the most diversified ecosystem on Earth as well as the least studied one. -

Pawson, National Museum of Natural History, Smithsonian Institution, Washington DC 20013-7012, USA. E-mail: [email protected] Abstract A new species in the family Bathycrinidae is described from abyssal depths from the Bahamas. It is referred to the recently established genus Discolocrinus, which formerly comprised a single species D. thieli Mironov, 2008 from the Eastern Pa- cific. Discolocrinus iselini n. sp. is characterized by large body size, high tegmen with tube-like upper region, extremely elongated IBr1 and IBr2, large knobby processes on primibrachials, and overgrowth of soft tissue on the pinnules, the tis- sue containing numerous perforated or imperforate ossicles of varying size and form. Differences between Discolocrinus and other bathycrinids may seem to be of taxonomic importance at the family level, but knowledge of the morphology and variability of both species of Discolocrinus is incomplete and, until a richer material becomes available, the genus should remain in family Bathycrinidae. Representatives of five families with xenomorphic stalks were examined to characterize the genera on the basis of number or form of knobby processes. -

Echinodermata
Echinodermata Bruce A. Miller The phylum Echinodermata is a morphologically, ecologically, and taxonomically diverse group. Within the nearshore waters of the Pacific Northwest, representatives from all five major classes are found-the Asteroidea (sea stars), Echinoidea (sea urchins, sand dollars), Holothuroidea (sea cucumbers), Ophiuroidea (brittle stars, basket stars), and Crinoidea (feather stars). Habitats of most groups range from intertidal to beyond the continental shelf; this discussion is limited to species found no deeper than the shelf break, generally less than 200 m depth and within 100 km of the coast. Reproduction and Development With some exceptions, sexes are separate in the Echinodermata and fertilization occurs externally. Intraovarian brooders such as Leptosynapta must fertilize internally. For most species reproduction occurs by free spawning; that is, males and females release gametes more or less simultaneously, and fertilization occurs in the water column. Some species employ a brooding strategy and do not have pelagic larvae. Species that brood are included in the list of species found in the coastal waters of the Pacific Northwest (Table 1) but are not included in the larval keys presented here. The larvae of echinoderms are morphologically and functionally diverse and have been the subject of numerous investigations on larval evolution (e.g., Emlet et al., 1987; Strathmann et al., 1992; Hart, 1995; McEdward and Jamies, 1996)and functional morphology (e.g., Strathmann, 1971,1974, 1975; McEdward, 1984,1986a,b; Hart and Strathmann, 1994). Larvae are generally divided into two forms defined by the source of nutrition during the larval stage. Planktotrophic larvae derive their energetic requirements from capture of particles, primarily algal cells, and in at least some forms by absorption of dissolved organic molecules. -

ZooKeys 663: 1–19. https://doi.org/10.3897/zookeys.663.11413 Abstract The first morphological observation of a euryalid brittle star,Asteronyx loveni, using non-destructive X- ray micro-computed tomography (µCT) was performed. The body of euryalids is covered by thick skin, and it is very difficult to observe the ossicles without dissolving the skin. Computed tomography with micrometer resolution (approximately 4.5–15.4 µm) was used to construct 3D images of skeletal ossicles and soft tissues in the ophiuroid’s body. Shape and positional arrangement of taxonomically important ossicles were clearly observed without any damage to the body. -

Av. Vereador Olimpio Grande, S/N, CEP 49500-000, Itabaiana, SE, Brasil Abstract.- This study provides an updated morphological description of Asteroporpa (Asteroporpa) annulata based on one specimen from the northeastern coast of Brazil, thus validating the previously uncertain occurrence of this species there. We also provide notes on the known geographic distribution of the subgenus Asteroporpa (Asteroporpa) and comments on ecological aspects of this taxon. Given our limited knowledge of the Euryalida fauna along the Brazilian coast, these new records are important for understanding the distribution, dispersal and speciation patterns of this group. The number of Euryalida reported for the Brazilian coast is increased to eight with this record. Key words: Echinodermata, taxonomy, ophiurans, geographical distribution INTRODUCTION The order Euryalida represents a group of brittle stars, slowly than in other echinoderm taxa (Baker 1980).
