ZooKeys 581: 127–140. doi: 10.3897/zookeys.581.8044 Abstract Bothriembryon sophiarum sp. n. is described, based on shell and anatomical morphology, from the coastal area of south-easternmost Western Australia. This is the first description of a new extant Australian bo- thriembryontid in 33 years. The shell of B. sophiarum is slender with a unique teleoconch sculpture. It is found in low coastal scrub on cliff edges and escarpments and because of its restricted distribution, qualifies as a short range endemic. Keywords Western Australia, Orthalicoidea, ecology, anatomy, micro-CT Introduction Along with the diverse and generally more northern and eastern Camaenidae, the en- demic Australian genus Bothriembryon (Bothriembryontidae) forms a large and charac- teristic component of the Australian terrestrial molluscan fauna, particularly in Western Australia (Iredale 1939; Kershaw 1985; Solem 1998). -

Characterization of Arm Autotomy in the Octopus, Abdopus Aculeatus (D’Orbigny, 1834)
Characterization of Arm Autotomy in the Octopus, Abdopus aculeatus (d’Orbigny, 1834) By Jean Sagman Alupay A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Integrative Biology in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Roy L. Caldwell, Chair Professor David Lindberg Professor Damian Elias Fall 2013 ABSTRACT Characterization of Arm Autotomy in the Octopus, Abdopus aculeatus (d’Orbigny, 1834) By Jean Sagman Alupay Doctor of Philosophy in Integrative Biology University of California, Berkeley Professor Roy L. Caldwell, Chair Autotomy is the shedding of a body part as a means of secondary defense against a predator that has already made contact with the organism. This defense mechanism has been widely studied in a few model taxa, specifically lizards, a few groups of arthropods, and some echinoderms. All of these model organisms have a hard endo- or exo-skeleton surrounding the autotomized body part. There are several animals that are capable of autotomizing a limb but do not exhibit the same biological trends that these model organisms have in common. As a result, the mechanisms that underlie autotomy in the hard-bodied animals may not apply for soft bodied organisms. A behavioral ecology approach was used to study arm autotomy in the octopus, Abdopus aculeatus. Investigations concentrated on understanding the mechanistic underpinnings and adaptive value of autotomy in this soft-bodied animal. A. aculeatus was observed in the field on Mactan Island, Philippines in the dry and wet seasons, and compared with populations previously studied in Indonesia. -
Gastropoda, Acteonidae) and Remarks on the Other Mediterranean Species of the Family Acteonidae D’Orbigny, 1835

It is placed in Callostracon and named C. Hamlin, 1884, tyrrhenicum. The description is based on shell morpho- logyonly. Remarks on the four bathyal and the three infralittoral species ofthe familyActeonidae known from the Mediterranean Sea, are also featured.

INTRODUCTION In the framework of carried an investigation out over the past decade, we continue to characterize the bathyal faunal assemblages from the Central Tyrrhenian Sea, off the Latial coast (Italy) (Smriglio et al., 1987, 1990, 1992, 1993). In particular, we are interested in the molluscan fauna occurring in the deep-sea coral (biocoenose des and des coraux blancs, CB) muddy-bathyal (biocoenose vases bathyales, VB) commu- nities & of this In this we describe of (Peres Picard, 1964) area. paper a new species acteonid, Callostracon tyrrhenicum, from material dredged in a deep-sea coral bank off the coast. Latial Among the molluscan fauna associated with C. tyrrhenicum, we have iden- tified four which bathyal acteonids, we think worth reporting: Acteon monterosatoi Crenilabium Dautzenberg, 1889, exile (Jeffreys, 1870, ex Forbes ms.), Japonacteon pusillus and Liocarenus (McGillavray, 1843), globulinus (Forbes, 1844). -
THE LISTING of PHILIPPINE MARINE MOLLUSKS Guido T
August 2017 Guido T. Poppe A LISTING OF PHILIPPINE MARINE MOLLUSKS - V1.00 THE LISTING OF PHILIPPINE MARINE MOLLUSKS Guido T. Poppe INTRODUCTION The publication of Philippine Marine Mollusks, Volumes 1 to 4 has been a revelation to the conchological community. Apart from being the delight of collectors, the PMM started a new way of layout and publishing - followed today by many authors. Internet technology has allowed more than 50 experts worldwide to work on the collection that forms the base of the 4 PMM books. This expertise, together with modern means of identification has allowed a quality in determinations which is unique in books covering a geographical area. Our Volume 1 was published only 9 years ago: in 2008. Since that time “a lot” has changed. Finally, after almost two decades, the digital world has been embraced by the scientific community, and a new generation of young scientists appeared, well acquainted with text processors, internet communication and digital photographic skills. Museums all over the planet start putting the holotypes online – a still ongoing process – which saves taxonomists from huge confusion and “guessing” about how animals look like. Initiatives as Biodiversity Heritage Library made accessible huge libraries to many thousands of biologists who, without that, were not able to publish properly. The process of all these technological revolutions is ongoing and improves taxonomy and nomenclature in a way which is unprecedented. All this caused an acceleration in the nomenclatural field: both in quantity and in quality of expertise and fieldwork. The above changes are not without huge problematics. Many studies are carried out on the wide diversity of these problems and even books are written on the subject. -
A Regional Shellfish Hatchery for the Wider Caribbean Assessing Its Feasibility and Sustainability
FAO ISSN 2070-6103 19 FISHERIES AND AQUACULTURE PROCEEDINGS FAO FISHERIES AND AQUACULTURE PROCEEDINGS 19 19 A regional shellfish hatchery for the Wider Caribbean Assessing its feasibility and sustainability A regional shellfish hatchery for the Wider Caribbean – Assessing its feasibility and sustainability A regional FAO Regional Technical Workshop A regional shellfish hatchery for 18–21 October 2010 Kingston, Jamaica the Wider Caribbean It is widely recognized that the development of aquaculture in Assessing its feasibility and sustainability the Wider Caribbean Region is inhibited, in part, by the lack of technical expertise, infrastructure, capital investment and human resources. Furthermore, seed supply for native species FAO Regional Technical Workshop relies, for the most part, on natural collection, subject to 18–21 October 2010 natural population abundance with wide yearly variations. This Kingston, Jamaica situation has led to the current trend of culturing more readily available exotic species, but with a potentially undesirable impact on the natural environment. The centralizing of resources available in the region into a shared facility has been recommended by several expert meetings over the past 20 years. The establishment of a regional hatchery facility, supporting sustainable aquaculture through the seed production of native molluscan species was discussed at the FAO workshop “Regional shellfish hatchery: A feasibility study” held in Kingston, Jamaica, in October 2010, by representatives of Caribbean Governments and experts in the field. Molluscan species are particularly targeted due to their culture potential in terms of known techniques, simple grow-out technology and low impact on surrounding environment. It is proposed that a regional molluscan hatchery would produce seed for sale and distribution to grow-out operations in the region as well as provide technical support for the research on new species. -

The Cephalic Sensory Organs of Acteon Tornatilis (Linnaeus, 1758) (Gastropoda Opisthobranchia) – Cellular Innervation Patterns As a Tool for Homologisation*
Bonner zoologische Beiträge Band 55 (2006) Heft 3/4 Seiten 311–318 Bonn, November 2007 The cephalic sensory organs of Acteon tornatilis (Linnaeus, 1758) (Gastropoda Opisthobranchia) – cellular innervation patterns as a tool for homologisation* Sid STAUBACH & Annette KLUSSMANN-KOLB1) 1)Institute for Ecology, Evolution and Diversity – Phylogeny and Systematics, J. W. Goethe-University, Frankfurt am Main, Germany *Paper presented to the 2nd International Workshop on Opisthobranchia, ZFMK, Bonn, Germany, September 20th to 22nd, 2006 Abstract. Gastropoda are guided by several sensory organs in the head region, referred to as cephalic sensory organs (CSOs). This study investigates the CSO structure in the opisthobranch, Acteon tornatilis whereby the innervation pat- terns of these organs are described using macroscopic preparations and axonal tracing techniques. A bipartite cephalic shield and a lateral groove along the ventral side of the cephalic shield was found in A. tornatilis. Four cerebral nerves can be described innervating different CSOs: N1: lip, N2: anterior cephalic shield and lateral groove, N3 and Nclc: posterior cephalic shield. Cellular innervation patterns of the cerebral nerves show characteristic and con- stant cell clusters in the CNS for each nerve. We compare these innervation patterns of A. tornatilis with those described earlier for Haminoea hydatis (STAUBACH et al. in press). Previously established homologisation criteria are used in order to homologise cerebral nerves as well as the organs innervated by these nerves. Evolutionary implications of this homologisation are discussed. Keywords. Haminoea hydatis, Cephalaspidea, axonal tracing, homology, innervation patterns, lip organ, Hancock´s organ. 1.
