Reid iving cephalopods include nautiluses, bobtail and bottle squids, pygmy cuttlefishes, cuttlefishes, Lsquids, and octopuses. While they may not be as diverse a group as other molluscs or as the bony fishes in terms of number of species (about 600 cephalopod species described worldwide), they are very abundant and some reach large sizes. Hence they are of considerable ecological and commercial fisheries importance globally and in the Western Central Pacific. Remarks on MajorREMARKS Groups of CommercialON MAJOR Importance GROUPS OF COMMERCIAL IMPORTANCE Nautiluses (Family Nautilidae) Nautiluses are the only living cephalopods with an external shell throughout their life cycle. This shell is divided into chambers by a large number of septae and provides buoyancy to the animal. The animal is housed in the newest chamber. A muscular hood on the dorsal side helps close the aperture when the animal is withdrawn into the shell. Nautiluses have primitive eyes filled with seawater and without lenses. They have arms that are whip-like tentacles arranged in a double crown surrounding the mouth. Although they have no suckers on these arms, mucus associated with them is adherent. Nautiluses are restricted to deeper continental shelf and slope waters of the Indo-West Pacific and are caught by artisanal fishers using baited traps set on the bottom. The flesh is used for food and the shell for the souvenir trade. Specimens are also caught for live export for use in home aquaria and for research purposes.

  • Growth, Tolerance to Low Salinity, and Osmoregulation in Decapod Crustacean Larvae
    Vol. 12: 249–260, 2011 AQUATIC BIOLOGY Published online June 1 doi: 10.3354/ab00341 Aquat Biol Growth, tolerance to low salinity, and osmoregulation in decapod crustacean larvae Gabriela Torres1, 2,*, Luis Giménez1, Klaus Anger2 1School of Ocean Sciences, Bangor University, Menai Bridge, LL59 5AB, UK 2Biologische Anstalt Helgoland, Foundation Alfred Wegener Institute for Polar and Marine Research, 27498 Helgoland, Germany ABSTRACT: Marine invertebrate larvae suffer high mortality due to abiotic and biotic stress. In planktotrophic larvae, mortality may be minimised if growth rates are maximised. In estuaries and coastal habitats however, larval growth may be limited by salinity stress, which is a key factor select- ing for particular physiological adaptations such as osmoregulation. These mechanisms may be ener- getically costly, leading to reductions in growth. Alternatively, the metabolic costs of osmoregulation may be offset by the capacity maintaining high growth at low salinities. Here we attempted identify general response patterns in larval growth at reduced salinities by comparing 12 species of decapod crustaceans with differing levels of tolerance to low salinity and differing osmoregulatory capability, from osmoconformers to strong osmoregulators. Larvae possessing tolerance to a wider range in salinity were only weakly affected by low salinity levels. Larvae with a narrower tolerance range, by contrast, generally showed reductions in growth at low salinity. The negative effect of low salinity on growth decreased with increasing osmoregulatory capacity. Therefore, the ability to osmoregulate allows for stable growth. In euryhaline larval decapods, the capacity to maintain high growth rates in physically variable environments such as estuaries appears thus to be largely unaffected by the energetic costs of osmoregulation.

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.

This is one of the most widely distributed and conspicuous families of squids in the world. Most species are exploited commercially. Todarodes pacificus makes up the bulk of the squid landings in Japan (up to 600 000 t annually) and may comprise at least 1/2 the annual world catch of cephalopods.In various parts of the West- ern Central Atlantic, 6 species of ommastrephids currently are fished commercially or for bait, or have a potential for exploitation. Ommastrephids are powerful swimmers and some species form large schools. Some neritic species exhibit strong seasonal migrations, wherein they occur in huge numbers in inshore waters where they are accessable to fisheries activities. The large size of most species (commonly 30 to 50 cm total length and up to 120 cm total length) and the heavily mus- cled structure, make them ideal for human con- ventral view sumption. Similar families occurring in the area Onychoteuthidae: tentacular clubs with claw-like hooks; funnel locking apparatus a simple, straight groove.

In his formal plan for the Insti- tution, Joseph Henry articulated a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge not strictly professional." This keynote of basic research has been adhered to over the years in the issuance of thousands of titles in serial publications under the Smith- sonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Annals of Flight Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in History and Technology In these series, the Institution publishes original articles and monographs dealing with the research and collections of its several museums and offices and of professional colleagues at other institutions of learning.

Bublitz 4- o Fairbanks, Alaska '3 < o May 1981 H ABSTRACT The systematic relationships within the cephalopod family Gonatidae were examined utilizing specimens collected from the southeastern Bering Sea. Ten species; Gonatus onyx, Gonatus madokai, Gonatus tinvo3 Gonatus bewyi, Gonatus pyvos3 Gonatus sp., Gonatus type A, BevvyteuthLs magistev3 Berryteuthis anonychus3 and Gonatopsis bovealis; were identified. Included in these are the identification of a probable new species, Gonatus sp., the verification of a questionable species, Gonatus tinro, and the classification of previously described but unclassified developmental stages. Morphometric characters were used for a retrogression analysis of each species' development. The developmental stages for those species found in the study area are described and illustrated in detail. The taxonomic and morphometric characters of the species are compared. Two closely allied species, Gonatus bevvyi and Gonatus sp. are compared and contrasted. A brief an§J.ysis of the growth and development of the genus Gonatus is also given. ACKNOWLEDGEMENT S I gratefully acknowledge the assistance and encouragement given me by a large number of people, both in the United States and Japan.
