Zum Auftreten Der Kopfschildschnecke Haminoea Solitaria (SAY 1822) Im Bereich Der Deutschen Ostseeküste
1 Mitt. dtsch. malakozool. Ges. 99 1 – 20 Frankfurt a. M., Juni 2018 Zum Auftreten der Kopfschildschnecke Haminoea solitaria (SAY 1822) im Bereich der deutschen Ostseeküste WOLFGANG WRANIK & MANUEL ANTONIO E. MALAQUIAS Abstract: The presence of the Cephalaspidean gastropod Haminoea solitaria (SAY 1822) is reported for the first time on the Baltic coast of Germany. In August 2016 a larger number of specimens were recorded in a shallow area of the island of Poel (Wismar Bay, Mecklenburg-Western Pomerania, Germany). Snails were found bur- rowing just under the surface of fine-grained sediments and reproducing by gelatinous egg balls anchored on the substrate. Records of smaller specimens of the snail in the Flensburg Firth and in the Kiel Bay in Octo- ber/November 2016 and spring 2017 from deeper areas (about 10 m), records in other shallow parts of the Wis- mar Bay, at Travemuende and at Neustadt/Holstein in 2017 and a possible record from Tjärnö, Sweden (North- ern Skagerrak), indicate, that the species is already well established in European waters and that its range is probably larger than currently known. It might be that it has remained undetected in other areas due to its bur- rowing lifestyle and difficulties in identification. H. solitaria, belonging to the family Haminoeidae, is native to the West Atlantic coast of North America where it occurs in shallow brackish and salt water from the Gulf of Saint Lawrence (Canada) to Florida (USA). European specimens were studied based on shells, live animals, external morphology and anatomy aided by scanning electron microscopy and molecular sequencing. -

Possible Anti-Predation Properties of the Egg Masses of the Marine Gastropods Dialula Sandiegensis, Doris Montereyensis and Haminoea Virescens (Mollusca, Gastropoda)
Possible anti-predation properties of the egg masses of the marine gastropods Dialula sandiegensis, Doris montereyensis and Haminoea virescens (Mollusca, Gastropoda) E. Sally Chang1,2 Friday Harbor Laboratories Marine Invertebrate Zoology Summer Term 2014 1Friday Harbor Laboratories, University of Washington, Friday Harbor, WA 98250 2University of Kansas, Department of Ecology and Evolutionary Biology, Lawrence, KS 66044 Contact information: E. Sally Chang Dept. of Ecology and Evolutionary Biology University of Kansas 1200 Sunnyside Avenue Lawrence, KS 66044 [email protected] Keywords: gastropods, nudibranchs, Cephalaspidea, predation, toxins, feedimg, crustaceans Chang 1 Abstract Many marine mollucs deposit their eggs on the substrate encapsulated in distinctive masses, thereby leaving the egg case and embryos vulnerable to possible predators and pathogens. Although it is apparent that many marine gastropods possess chemical anti-predation mechanisms as an adult, it is not known from many species whether or not these compounds are widespread in the egg masses. This study aims to expand our knowledge of egg mass predation examining the feeding behavior of three species of crab when offered egg mass material from three gastropods local to the San Juan Islands. The study includes the dorid nudibranchs Diaulula sandiegensis and Doris montereyensis and the cephalospidean Haminoea virescens. The results illustrate a clear rejection of the egg masses by all three of the crab species tested, suggesting anti- predation mechanisms in the egg masses for all three species of gastropod. Introduction Eggs that are laid and then left by the parents are vulnerable to a variety of environmental stressors, both biotic and abiotic. A common, possibly protective strategy among marine invertebrates is to lay encapsulated aggregations of embryos in jelly masses (Pechenik 1978), where embryos live for all or part of their development. -

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. INTRODUCTION Gastropoda are guided by several organs in the head re- phylogenetic position of Acteonoidea within Opistho- gion which are assumed to have primarily chemo- and branchia unsettled. -

And “Sheeting:” Strategies Utilized by Haminoea Vesicula to Maintain Stability on Different Substrates
“Hooking” and “Sheeting:” strategies utilized by Haminoea vesicula to maintain stability on different substrates Justin Sui12, Rachel Merz12 Blinks-Beacon REU Internship 2014 Summer 2014 1 Friday Harbor Laboratories, University of Washington, Friday Harbor, WA 98250 2 Department of Biology, Swarthmore College, Swarthmore, PA 19081 Contact information: Justin Sui Swarthmore College 500 College Avenue Swarthmore, PA 19081 [email protected] Keywords: bubble snail, Haminoea vesicula, substrate, gastropod, drag, eelgrass, sediment, sheeting, hooking Sui 1 Abstract Many marine gastropods face the challenge of adhering to substrates under adverse flow conditions. Some species live on both solid and sedimentary substrates, although how these substrate generalists resist detachment from materials with fundamentally different mechanical properties is not well studied. We used field observations and flow tank experiments to compare the capabilities and tactics of Haminoea vesicula, an opisthobranch gastropod, when exposed to destabilizing flow on its native sand and eelgrass. Velocities of outgoing and incoming spring tides in the tidal creeks and over and within eelgrass beds where H. vesicula live at False Bay, San Juan Island, WA ranged from 1 to 30 cm/s. In a flow tank, snails’ resistance to current depended on substrate and orientation. On eelgrass, snails moving into flow maintained their position at velocities exceeding 40 cm/s, but were more vulnerable when facing away or sideways to flow (falling off at mean velocities of 25 and 32 cm/s respectively). In the latter orientation, snails would often rotate into flow by hooking onto the leading edge of eelgrass with the anterior edge of the cephalic shield. In this position, snails resisted flows exceeding 40 cm/s. -

A reproducing population was discovered in fouling communities on floating docks in South San Francisco Bay, California, in March 2016. Dendronotus orientalis joins a large number of introduced marine invertebrates that have taken up residence in San Francisco Bay. Key words: introduced, nudibranch, San Francisco Bay, citizen science Introduction Results and discussion The San Francisco Bay, in Central California (USA), On 29 March 2016, a single specimen of an unusual, supports a worldwide array of introduced marine unidentified nudibranch was discovered at the Marine animals and plants, a characteristic that is due in Science Institute floating docks in Redwood City large part to extensive international shipping activity (37.5049ºN; 122.2171ºW), in southern San Francisco and a long history of the importation of commercial Bay (Figure 1). The nudibranch was found at 1.5 m oysters from the Western Atlantic and Western depth on a rope heavily covered with the hydroid Pacific Oceans (Cohen and Carlton 1995; Cohen and Ectopleura sp., which it was observed eating (Figure Carlton 1998; Carlton and Cohen 2007).
