Around 1,500 living species of starfish occur on the seabed in all the world's oceans, from the tropics to subzero polar waters. They are found from the intertidal zone down to abyssal depths, 6,000m below the surface. Starfish typically have a central disc and five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. -

Foregut anatomy of the Cochlespirinae (Gastropoda, Conoidea, Turridae) Alexandra I. MEDINSKAYA A. N. Severtzov Institute of Problems of Evolution, Leninsky Prospect 33, Moscow 117071 (Russia) Medinskaya A. I. 1999. — Foregut anatomy of the Cochlespirinae (Gastropoda. Conoidea. Turridae). Zoosystema2\ (2): 171-198. ABSTRACT The foregut anatomy of 20 species, belonging to eight genera, of the sub family Cochlespirinae is described. A cladistic analysis based on several most important characters (morphology of proboscis, position of buccal sphinc ters, histology of venom gland, position of the venom gland opening, struc ture of muscular bulb, and morphology of radular teeth) revealed three more or less well-defined groups within the subfamily. The main feature characte rizing the subfamily as a whole and separating groups within it, appeared to be the structure of venom gland and its muscular bulb. The subgenus KEYWORDS Cochlespirinae, Sibogasyrinx of the genus Leucosyrinx was shown to deserve a genus status.

Fundación La Salle de Ciencias Naturales. Apartado 144 Porlama,. Isla de Margarita, Venezuela. ABSTRACT Marine endolithic and wood-boring bivalve mollusks living in rocks, corals, wood, and shells were surveyed on the Caribbean coast of Venezuela at Isla Margarita between 2004 and 2008. These surveys were supplemented with boring mollusk data from malacological collections in Venezuelan museums. A total of 571 individuals, corresponding to 3 orders, 4 families, 15 genera, and 20 species were identified and analyzed. The species with the widest distribution were: Leiosolenus aristatus which was found in 14 of the 24 localities, followed by Leiosolenus bisulcatus and Choristodon robustus, found in eight and six localities, respectively. The remaining species had low densities in the region, being collected in only one to four of the localities sampled. The total number of species reported here represents 68% of the boring mollusks that have been documented in Venezuelan coastal waters. This study represents the first work focused exclusively on the examination of the cryptofaunal mollusks of Isla Margarita, Venezuela. KEY WORDS Shipworms, cryptofauna, Teredinidae, Pholadidae, Gastrochaenidae, Mytilidae, Petricolidae, Margarita Island, Isla Margarita Venezuela, boring bivalves, endolithic. INTRODUCTION The lithophagans (Mytilidae) are among the Bivalve mollusks from a range of families have more recognized boring mollusks. -

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. -
Life Cycle of the Symbiotic Scaleworm Arctonoe Vittata (Polychaeta: Polynoidae)
Ophelia Suppl. 5: 305-312 (February 1991) Life Cycle of the Symbiotic Scaleworm Arctonoe vittata (Polychaeta: Polynoidae) T A . Britayev A.N. Severtzov Institute of Animal Morphology and Ecology Lenin Avenue 33, Moscow W-71, U.S.S .R . ABSTRACT The reproductive biology, some stages of de velopment, size structure, distribution by hosts, behaviour and tr aumatism were studied in a population of Arctonoeoittata at Vostok Bay (Sea ofJapan). The species is associat ed with the starfish Asterias amurensis and the limpet A cmaea pallida. It is a polytelic species with an annual reproductive cycle. Spawning occu rs during June and July. Larval development is planktotrophic and lasts about a month. Distribution of young specimens is random as a result of settlement. Analysis of different size groups of sym bionts on starfish reveals a uniformity in their distribution, wh ich is increased due to the size of the pol ynoids. Intraspecific aggressive behaviour is characteri stic for thi s spe cies. Aggressive interactions among the worms stim ula te one or mor e of them to leave a host and move onto another host - mollu sc or starfish - result ing in a uniform distribution oflarge symbionts on the hosts . For at lea st part of the symbiont population, the starfish Astenas amurensis serv es as the intermediate host and the limpet Acmaea pallida as the definitive host. Keyword s: Polychaeta, Polynoid ae, Arctonoe, sym bionts, intraspecific aggression, distribution, reproduction.

An outline of cassoidean phylogeny (Mollusca, Gastropoda). — Contr. Tert. Quatern. Geo!., 32(4): 97-132, 43 figs. Leiden, December 1995. The phylogeny of cassoidean gastropods is reviewed, incorporating most of the biological and palaeontological data from the literature. Several characters have been checked personally and some new data are presented and included in the cladistic analysis. The Laubierinioidea, Calyptraeoidea and Capuloidea are used as outgroups. Twenty-three apomorphies are discussed and used to define cassoid relations at the subfamily level. A classification is presented in which only three families are recognised. The Ranellidae contains the subfamilies Bursinae, Cymatiinae and Ranellinae. The Pisanianurinae is removed from the Ranellidae and attributed to the Laubierinioidea.The Cassidae include the Cassinae, Oocorythinae, Phaliinae and Tonninae. The Ranellinae and Oocorythinae are and considered the of their families. The third the both paraphyletic taxa are to represent stem-groups family, Personidae, cannot be subdivided and for anatomical evolved from Cretaceous into subfamilies reasons probably the same Early gastropod ancestor as the Ranellidae. have from Ranellidae the Late Cretaceous. The Cassidae (Oocorythinae) appears to branched off the (Ranellinae) during The first significant radiation of the Ranellidae/Cassidaebranch took place in the Eocene. The Tonninae represents the youngest branch of the phylogenetic tree. Key words — Neomesogastropoda, Cassoidea, ecology, morphology, fossil evidence, systematics. Dr F.
