The Biology of Terebra Gouldi Deshayes, 1859, and a Discussion Oflife History Similarities Among Other Terebrids of Similar Proboscis Type!
Pacific Science (1975), Vol. 29, No.3, p. 227-241 Printed in Great Britain The Biology of Terebra gouldi Deshayes, 1859, and a Discussion ofLife History Similarities among Other Terebrids of Similar Proboscis Type! BRUCE A. MILLER2 ABSTRACT: Although gastropods of the family Terebridae are common in sub tidal sand communities throughout the tropics, Terebra gouldi, a species endemic to the Hawaiian Islands, is the first terebrid for which a complete life history is known. Unlike most toxoglossan gastropods, which immobilize their prey through invenomation, T. gouldi possesses no poison apparatus and captures its prey with a long muscular proboscis. It is a primary carnivore, preying exclusively on the enteropneust Ptychodera flava, a nonselective deposit feeder. The snail lies com pletely buried in the sand during the day, but emerges to search for prey after dark. Prey are initially detected by distance chemoreception, but contact of the anterior foot with the prey is necessary for proboscis eversion and feeding. The sexes in T. gouldi are separate, and copulation takes place under the sand. Six to eight spherical eggs are deposited in a stalked capsule, and large numbers of capsules are attached in a cluster to coral or pebbles. There is no planktonic larval stage. Juveniles hatch through a perforation in the capsule from 30-40 days after development begins and immediately burrow into the sand. Growth is relatively slow. Young individuals may grow more than 1 cm per year, but growth rates slow considerably with age. Adults grow to a maximum size of 8 cm and appear to live 7-10 years. -

The potential of conoidean toxins has been realized with the distribution of the first Conus (cone snail) drug, Prialt (ziconotide), an analgesic used to alleviate chronic pain in HIV and cancer patients. Cone snail toxins (conotoxins) are highly variable, a consequence of a high mutation rate associated to duplication events and positive selection. As Conus and terebrids diverged in the early Paleocene, the toxins from terebrids (teretoxins) may demonstrate highly divergent and unique functionalities. Recent analyses of the Terebri- dae, a largely distributed family with more than 300 described species, indicate they have evolutionary and phar- macological potential. Based on a three gene (COI, 12S and 16S) molecular phylogeny, including ~50 species from the West-Pacific, five main terebrid lineages were discriminated: two of these lineages independently lost their venom apparatus, and one venomous lineage was previously unknown. -

Morphology of Crab Predation Scars on Recent and Fossil Turritellid T Gastropods ⁎ Nadia D

Pierrehumberta,1, Warren D. Allmona,b, a Department of Earth and Atmospheric Sciences, Cornell University, Ithaca, NY 14853, USA b Paleontological Research Institution, 1259 Trumansburg Road, Ithaca, NY 14850, USA ABSTRACT When nonlethal attempted predation breaks the aperture of a gastropod shell, the break is preserved as a scar which is frequently visible in the fossil record. Such scars are very frequently observed on fossil and living Turritellidae, a family of high-spired marine gastropods, but little is known about which predators make such scars or how they do so. If the form of these scars on fossil shells could be better interpreted biologically, a large data set of predation scars might become available for analysis. We experimented with live turritellids (Turritella banksi) and four species of crabs from the family Xanthidae (Panopeus sp., Eurypanopeus planus, Leptodius tabo- ganus, and Xanthodius sternberghii) in Panama in order to investigate factors contributing to the breakage mor- phology resulting from crab predation on turritellid shells. Qualitative examination of scar morphology resulting from attacks by different crab species shows that particular crab species can cause distinctively-shaped scars, although some shapes of scars can be created by more than one crab species. Multivariate analysis of these scars reveals that scar morphologies arising from different crab species fall on overlapping continua in morphospace. Incorporating the shapes of fossil scars into these analyses reveals that fossil scars are similar to many of those created in the aquaria, and that scar shape can be accurately predicted by predator species. -
Evolution of the Toxoglossa Venom Apparatus As Inferred by Molecular Phylogeny of the Terebridae

These marine animals are generally characterized by a venom apparatus that consists of a muscular venom bulb and a tubular venom gland. The toxoglossan radula, often compared with a hypodermic needle for its use as a conduit to inject toxins into prey, is considered a major anatomical breakthrough that assisted in the successful initial radiation of these animals in the Cretaceous and early Tertiary. The pharmacological success of toxins from cone snails has made this group a star among biochemists and neuroscientists, but very little is known about toxins from the other Toxoglossa, and the phylogeny of these families is largely in doubt. Here we report the first molecular phylogeny for the Terebridae and use the results to infer the evolution of the venom apparatus for this group. Our findings indicate that most of the genera of terebrids are polyphyletic, and one species (‘‘Terebra’’ (s.l.) jungi) is the sister group to all other terebrids. -
Marine Gastropods of American Samoa Introduction
Micronesica 41(2):237–252, 2011 Marine gastropods of American Samoa D.P. Brown Isle Royale National Park, Houghton, MI 49931 Abstract—Collected for food for over 3,000 years by the indigenous Samoan people, marine gastropods in American Samoa have never been collected and cataloged for science. This study documents 385 marine gastropods from 50 families occurring in the U.S. territory of American Samoa. Ten of these are listed by genus only and one by family. The num- ber of gastropods currently reported is likely significantly underestimated and a conservative estimate of the richness yet to be discovered. Introduction Molluscs have been collected in Samoa since the earliest inhabitants arrived some 3,000 years ago (Craig et al 2008, Kramer 1994, Kirch and Hunt, 1993, Nagaoka 1993). Much of this reef gleaning was directed at the cephalopods, the large and colorful giant clams (Tridacna spp.) and the larger marine snails such as Trochus spp, Lambis spp., Cassis spp., Turbo spp., and Tutufa spp., although any marine mollusc was likely taken if found (Munro 1999). While the limited archeological evidence provides an initial species list, this long history of the use of marine molluscs provided a very limited understanding of the marine gastro- SRGVRIWKHDUFKLSHODJR(YHQDIWHU(XURSHDQFRQWDFWIHZVHULRXVRUDPDWHXUVKHOO collectors made the long voyage to the S. Pacific to catalog the gastropoda. Until very recently, and before the advent of SCUBA, much of the gastropod knowledge in the area came from the shallow depths available to free-divers, what could be dredged off the bottom, and what washed onto the shore. The first organized sci- entific investigations into the Samoan gastropods weren’t carried out until the 18th century by the La Perouse expedition. -
