We investigated the larval vertical dis- tribution and abundance of 9 meroplanktonic gastropod taxa (Margarites spp., Crepidula spp., Astyris lunata, Diaphana minuta, Littorinimorpha, Arrhoges occidentalis, Ilyanassa spp., Bittiolum alternatum and Nudibranchia), with similar morphology and swimming abilities, but different adult habitats and life-history strategies. We explored the role of physical (temperature, salinity, density, current velocities) and biological (fluorescence) factors, as well as periodic cycles (lunar phase, tidal state, diel period) in regulating larval vertical distribution. Using a pump, we collected plankton samples at 6 depths (3, 6, 9, 12, 18 and 24 m) at each tidal state, every 2 h over a 36 and a 26 h period, during a spring and neap tide, respectively, in St. George’s Bay, Nova Scotia. Con- currently, we measured temperature, salinity, density, fluorescence (as a proxy for chlorophyll, i.e. phytoplankton density), and current velocity. Larval abundance was most strongly related to tem- perature, except for Littorinimorpha and Crepidula spp., for which it was most strongly related to fluorescence. Margarites spp., A.

As humans, we interact with sea stars when they are used as research animals or displayed at public or private aquaria. Molecular research requires fresh tissues that have thus far been considered to be of the best quality if collected without euthanasia. This is the first paper describing a method to euthanize sea stars that still allows for sampling of high-quality tissue that can be used for advanced research. Since it can be difficult to tell if an invertebrate has died, it is important to use a two-step method where the first step makes it non-responsive and Citation: Wahltinez, S.J.; Kroll, K.J.; the next step ensures it has died.

  • The Advantages of the Pentameral Symmetry of the Starfish

Although starfish can evolve and live with other numbers of arms, the dominant species always show pentameral symmetry. We used mathematical and physical methods to analyze the superiority of starfish with five arms in comparison with those with a different number of arms with respect to detection, turning over, autotomy and adherence. In this study, we determined that starfish with five arms, although slightly inferior to others in one or two aspects, exhibit the best performance when the four aforementioned factors are considered together. In addition, five-armed starfish perform best on autotomy, which is crucially important for starfish survival. This superiority contributes to the dominance of five-armed starfish in evolution, which is consistent with the practical situation. Nevertheless, we can see some flexibility in the number and conformation of arms. The analyses performed in our research will be of great help in unraveling the mysteries of dominant shapes and structures.

  • Comparative Anatomy of Four Primitive Muricacean Gastropods: Implications for Trophonine Phylogeny
    ^/ -S/ COMPARATIVE ANATOMY OF FOUR PRIMITIVE MURICACEAN GASTROPODS: IMPLICATIONS FOR TROPHONINE PHYLOGENY M. G. HARASEWYCH DEPARTMENT OF INVERTEBRATE ZOOLOGY NATIONAL MUSEUM OF NATURAL HISTORY SMITHSONIAN INSTITUTION WASHINGTON, D.C. 20560, U.S.A. ABSTRACT The main features of the shell, head-foot, palliai complex, alimentary and reproductive systems of Trophon geversianus (Pallas), Boreotrophon aculeatus (Watson), Paziella pazi (Crosse), and Nucella lamellosa (Gmelin) are described, and phonetic and cladistic analyses based on subsets of these data presented. Similarities in shell morphology revealed by phenetic studies are interpreted as being due to convergence, and are indicative of similar habitats rather than of close phylogenetic relationships. Convergences are also noted in radular and stomach characters. Cladistic analyses of anatomical data support the following conclusions: 1 ) Thaididae are a primitive and ancient family of muricaceans forming a clade equal in taxonomic rank with Muncidae; 2) Within Muricidae, P. pazi more closely resembles the ancestral muricid phenotype than any trophonine; 3) Trophoninae comprise a comparatively recent monophyletic group with differences due to a subsequent austral adaptive radiation. The Muricidae are considered to be the most primitive and D'Attilio, 1976:13) a personal communication from E. H. family within Neogastropoda according to most (Thiele, Vokes "it appears likely that the most northern trophons are 1929; Wenz, 1941; Taylor and Sohl, 1962; Boss, 1982) but derived from the Paziella-Poiheha line, and that the several not all (Golikov and Starobogatov, 1975) recent classifica- austral forms that are unquestionably "trophonine" are prob- tions.
