Formation of Marginal Radular Teeth in Conoidea (Neogastropoda) and the Evolution of the Hypodermic Envenomation Mechanism
J. Zool., Lond.

Kantor 1 and John D. Taylor 2 1 A. N. Severtzov Institute of Problems of Evolution, Russian Academy of Sciences, Leninski prosp. 33, Moscow 117071, Russia. E-mail: [email protected] 2 Department of Zoology, The Natural History Museum, Cromwell Road, London SW7 5BD, U.K. E-mail: [email protected] (Accepted 21 October 1999) Abstract Four main types of radula are found within the gastropod superfamily Conoidea. Type 1, the Clavidae type has ®ve teeth in each row with comb-like laterals and ¯at pointed marginals. Type 2, the Turridae type has two or three teeth in a row with the marginals comprised of teeth with the duplex or wishbone form. Type 3, the Pseudomelatomidae/Pervicaciinae type has two or three teeth in a row with the marginals curved and solid. Type 4, the hypodermic type has two hollow, enrolled, marginal teeth in each row with the radular membrane reduced or absent. Study of the maturing teeth along the radular membrane in gastropods with the Type 2 radula shows that the duplex teeth are not formed from two separate elements but develop from a ¯at plate, by thickening of the tooth edges and elevation of the posterior edge from the membrane. Semi-enrolled and enrolled teeth of Pilsbryspira, Imaclava and Toxiclionella develop in a similar way. In Conidae where a vestigial radular membrane is attached only at the base of the teeth, the teeth are enrolled from ®rst formation in the radular sac. -

Foregut Anatomy of the Cochlespirinae (Gastropoda, Conoidea, Turridae)
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.

RESUME L'anatomie du système digestif des Cochlespirinae (Gastropoda, Conoidea, Turridae). L'anatomie du système digestif de 20 espèces, appartenant à huit genres de la sous-famille Cochlespirinae, est étudiée. Une analyse cladistique, fondée sur les plus importants caractères de ce groupe (la morphologie de la trompe, la disposition des sphincters, l'histologie de la glande à venin, la disposition de l'ouverture de la glande à venin, la structure de la poire musculaire et la mor phologie des dents de la radula) a permis de distinguet trois groupes plus ou moins homogènes. -
ABSTRACT Title of Dissertation: PATTERNS IN
ABSTRACT Title of Dissertation: PATTERNS IN DIVERSITY AND DISTRIBUTION OF BENTHIC MOLLUSCS ALONG A DEPTH GRADIENT IN THE BAHAMAS Michael Joseph Dowgiallo, Doctor of Philosophy, 2004 Dissertation directed by: Professor Marjorie L. Reaka-Kudla Department of Biology, UMCP Species richness and abundance of benthic bivalve and gastropod molluscs was determined over a depth gradient of 5 - 244 m at Lee Stocking Island, Bahamas by deploying replicate benthic collectors at five sites at 5 m, 14 m, 46 m, 153 m, and 244 m for six months beginning in December 1993. A total of 773 individual molluscs comprising at least 72 taxa were retrieved from the collectors. Analysis of the molluscan fauna that colonized the collectors showed overwhelmingly higher abundance and diversity at the 5 m, 14 m, and 46 m sites as compared to the deeper sites at 153 m and 244 m. Irradiance, temperature, and habitat heterogeneity all declined with depth, coincident with declines in the abundance and diversity of the molluscs. Herbivorous modes of feeding predominated (52%) and carnivorous modes of feeding were common (44%) over the range of depths studied at Lee Stocking Island, but mode of feeding did not change significantly over depth. One bivalve and one gastropod species showed a significant decline in body size with increasing depth. Analysis of data for 960 species of gastropod molluscs from the Western Atlantic Gastropod Database of the Academy of Natural Sciences (ANS) that have ranges including the Bahamas showed a positive correlation between body size of species of gastropods and their geographic ranges. There was also a positive correlation between depth range and the size of the geographic range. -

E-mail: [email protected] SUMMARY: Samples of a soft-bottom community from the continental slope of Campos Basin, off southeast Brazil, were obtained between 2001 and 2003 by the Research Vessel “Astro-Garoupa” with a 0.25 m2 box corer or by dredging with a Charcot dredge. A total of 177 samples were taken at depths ranging from 700 to 1950 m. Mollusks were present at all of the stations and among Gastropoda the Turridae showed the highest diversity. Within the family Cochlespirinae we found: Leucosyrinx tenoceras (Dall, 1889), L. verrillii (Dall, 1881), expanding the known distribution of the latter species farther south, and L.? subgrundifera (Dall, 1888), which is the first record of this species for the South Atlantic and the shallowest depth at which it has ever been found. Within the family Drilliinae we found Splendrillia centimata (Dall, 1889), also the first record of this species for the South Atlantic and its shallowest depth. Within the subfamily Oenopotinae we describe here three new species in the genus Oenopota Mörch, 1852: O. seraphina n. sp., O. diabula n. sp. and O. carioca n. sp.

Nearshore Marine Biodiversity of the Sunshine Coast, South-East Queensland: Inventory of molluscs, corals and fishes July 2010 Photo courtesy Ian Banks Baseline Survey Report to the Noosa Integrated Catchment Association, September 2010 Lyndon DeVantier, David Williamson and Richard Willan Executive Summary Nearshore reef-associated fauna were surveyed at 14 sites at seven locations on the Sunshine Coast in July 2010. The sites were located offshore from Noosa in the north to Caloundra in the south. The species composition and abundance of corals and fishes and ecological condition of the sites were recorded using standard methods of rapid ecological assessment. A comprehensive list of molluscs was compiled from personal observations, the published literature, verifiable unpublished reports, and photographs. Photographic records of other conspicuous macro-fauna, including turtles, sponges, echinoderms and crustaceans, were also made anecdotally. The results of the survey are briefly summarized below. 1. Totals of 105 species of reef-building corals, 222 species of fish and 835 species of molluscs were compiled. Thirty-nine genera of soft corals, sea fans, anemones and corallimorpharians were also recorded. An additional 17 reef- building coral species have been reported from the Sunshine Coast in previous publications and one additional species was identified from a photo collection. 2. Of the 835 mollusc species listed, 710 species could be assigned specific names. Some of those not assigned specific status are new to science, not yet formally described. 3. Almost 10 % (81 species) of the molluscan fauna are considered endemic to the broader bioregion, their known distribution ranges restricted to the temperate/tropical overlap section of the eastern Australian coast (Central Eastern Shelf Transition).
