Characterization of Tentacle Branching Morphogenesis in the Jellyfish
Characterization of tentacle branching morphogenesis in the jellyfish Cladonema pacificum Akiyo Fujiki1 Ayaki Nakamoto1 Gaku Kumano1 1 Research Center for Marine Biology, Asamushi, Graduate School of Life Sciences, Tohoku University To understand how tissues are shaped is a fundamental subject in the field of developmental biology. Among many tissue shaping events in animal development, we are particularly interested in branching morphogenesis. This study focuses on branching morphogenesis of the medusa tentacles of the jellyfish, Cladonema pacificum. One of the synapomorphic characters in the family Cladonematidae is that the medusa tentacles are branched with branches having nematocyst knobs and those having adhesive organs for landing. Therefore, studying tentacle branching mechanisms of Cladonema pacificum and other jellyfish species would provide us a useful insight into the evolutionary process of the acquisition of a novel morphological trait. In addition, since jellyfishes are not well-studied organisms and have simple cell constitutions, studying their branching morphogenesis might reveal a novel mechanism which might not be discovered in other branching phenomena such as those in the trachea of the fly, the mammalian lungs and angiogenesis of vertebrates. In this study, through analyses of the branching process of the Cladonema pacificum medusa tentacles, we try to obtain new knowledge to understand basic mechanisms of branching morphogenesis. As a first step toward this goal, we described how the tentacles are branched as well as how the branches with nematocyst knobs and adhesive organs form differently. To characterize the process of tentacle branching, we tracked the same tentacles during a period of one month starting from day 0, when small tentacles appeared on medusa buds. -

List of Bivalve Molluscs from British Columbia, Canada
List of Bivalve Molluscs from British Columbia, Canada Compiled by Robert G. Forsyth Research Associate, Invertebrate Zoology, Royal BC Museum, 675 Belleville Street, Victoria, BC V8W 9W2; [email protected] Rick M. Harbo Research Associate, Invertebrate Zoology, Royal BC Museum, 675 Belleville Street, Victoria BC V8W 9W2; [email protected] Last revised: 11 October 2013 INTRODUCTION Classification rankings are constantly under debate and review. The higher classification utilized here follows Bieler et al. (2010). Another useful resource is the online World Register of Marine Species (WoRMS; Gofas 2013) where the traditional ranking of Pteriomorphia, Palaeoheterodonta and Heterodonta as subclasses is used. This list includes 237 bivalve species from marine and freshwater habitats of British Columbia, Canada. Marine species (206) are mostly derived from Coan et al. (2000) and Carlton (2007). Freshwater species (31) are from Clarke (1981). Common names of marine bivalves are from Coan et al. (2000), who adopted most names from Turgeon et al. (1998); common names of freshwater species are from Turgeon et al. (1998). Changes to names or additions to the fauna since these two publications are marked with footnotes. Marine groups are in black type, freshwater taxa are in blue. Introduced (non-indigenous) species are marked with an asterisk (*). Marine intertidal species (n=84) are noted with a dagger (†). Quayle (1960) published a BC Provincial Museum handbook, The Intertidal Bivalves of British Columbia. Harbo (1997; 2011) provided illustrations and descriptions of many of the bivalves found in British Columbia, including an identification guide for bivalve siphons and “shows”. Lamb & Hanby (2005) also illustrated many species. -

(Hydrozoa, Anthomedusae) and the Use of 16S Rdna Sequences for Unpuzzling Systematic Relationships in Hydrozoa*

(Hydrozoa, Anthomedusae) and the use of 16S rDNA sequences for unpuzzling systematic relationships in Hydrozoa* BERND SCHIERWATER1,2 and ANDREA ENDER1 1Zoologisches Institut der J. W. Goethe-Universität, Siesmayerstr. 70, D-60054 Frankfurt, Germany, E-mail: [email protected] 2JTZ, Ecology and Evolution, Ti Ho Hannover, Bünteweg 17d, D-30559 Hannover, Germany. SUMMARY: A new hydrozoan species, Sarsia marii, is described by using morphological and molecular characters. Both morphological and 16S rDNA data place the new species together with other Sarsia species near the base of a clade that developed‚ “walking” tentacles in the medusa stage. The molecular data also suggest that the family Cladonematidae (Cladonema, Eleutheria, Staurocladia) is monophyletic. The taxonomic embedding of Sarsia marii n. sp. demonstrates the usefulness of 16S rDNA sequences for reconstructing phylogenetic relationships in Hydrozoa.

CNIDARIA Corals, Medusae, Hydroids, Myxozoans
FOUR Phylum CNIDARIA corals, medusae, hydroids, myxozoans STEPHEN D. CAIRNS, LISA-ANN GERSHWIN, FRED J. BROOK, PHILIP PUGH, ELLIOT W. Dawson, OscaR OcaÑA V., WILLEM VERvooRT, GARY WILLIAMS, JEANETTE E. Watson, DENNIS M. OPREsko, PETER SCHUCHERT, P. MICHAEL HINE, DENNIS P. GORDON, HAMISH J. CAMPBELL, ANTHONY J. WRIGHT, JUAN A. SÁNCHEZ, DAPHNE G. FAUTIN his ancient phylum of mostly marine organisms is best known for its contribution to geomorphological features, forming thousands of square Tkilometres of coral reefs in warm tropical waters. Their fossil remains contribute to some limestones. Cnidarians are also significant components of the plankton, where large medusae – popularly called jellyfish – and colonial forms like Portuguese man-of-war and stringy siphonophores prey on other organisms including small fish. Some of these species are justly feared by humans for their stings, which in some cases can be fatal. Certainly, most New Zealanders will have encountered cnidarians when rambling along beaches and fossicking in rock pools where sea anemones and diminutive bushy hydroids abound. In New Zealand’s fiords and in deeper water on seamounts, black corals and branching gorgonians can form veritable trees five metres high or more. In contrast, inland inhabitants of continental landmasses who have never, or rarely, seen an ocean or visited a seashore can hardly be impressed with the Cnidaria as a phylum – freshwater cnidarians are relatively few, restricted to tiny hydras, the branching hydroid Cordylophora, and rare medusae. Worldwide, there are about 10,000 described species, with perhaps half as many again undescribed. All cnidarians have nettle cells known as nematocysts (or cnidae – from the Greek, knide, a nettle), extraordinarily complex structures that are effectively invaginated coiled tubes within a cell. -
