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. -

Arabian Coral Reefs: Insights from Extremes ABSTRACTS for ORAL PRESENTATIONS (Alphabetical by Last Name of First Author)
Arabian Coral Reefs: Insights from Extremes ABSTRACTS FOR ORAL PRESENTATIONS (Alphabetical by last name of first author) Assessment of coral disease on northeastern Arabian reefs Aeby, G.; Work, T.; Howells, E.; Abrego, D.; Williams, G.; Burt, J. Disease is a natural component of all populations but disease outbreaks indicate a shift in the host- pathogen-environment triad of disease causation. Disease outbreaks in coral populations are occurring globally, and Arabian reefs are no exception. However, little work has been done to characterize diseases in this region. We examined coral disease at 17 sites across Abu Dhabi, Musandam, and Fujairah. Summertime surveys revealed 13 types of coral diseases including tissue loss of unknown etiology (white syndromes) in Porites, Platygyra, Dipsastrea, Cyphastrea, Acropora and Goniopora; growth anomalies in Porites, Platygyra, and Dipsastrea; black band disease in Platygyra, Dipsastrea, Acropora, Echinopora and Pavona; Porites bleached patches and Porites yellow-banded tissue loss disease. Across all reefs, the most widespread diseases were Platygyra growth anomalies (52.9% of all surveys), Acropora white syndrome (47.1%) and Porites bleached patches (35.3%). However, disease assemblages differed significantly among sub-regions with Abu Dhabi exhibiting the highest number of diseases and the greatest disease prevalence. Of particular concern, was a high number of localized outbreaks of tissue loss diseases (8 of 17 sites) primarily found in Abu Dhabi. Histopathological analyses revealed necrosis and varied potential disease agents including bacteria (Beggiatoa), fungi, metazoans, and algae associated with tissue loss diseases. Growth anomalies were characterized by proliferation of basal body wall (Acropora) or increased number and size of mesenterial filaments (Platygyra). -
Molecular Cytogenetic Analysis and Isolation of a 5S Rrna-Related Marker in the Scleractinian Coral Platygyra Contorta Veron 1990 (Hexacorallia, Anthozoa, Cnidaria)

P. contorta was karyotyped (2n=28) by conventional G- and C-bandings, and the karyogram revealed that about 50% of the metaphase spreads had a homogenously staining region (hsr) in the terminal portion of the long arm of chromosome 12. Fluorescence in situ hybridiza- tion (FISH) showed that this hsr consisted of rRNA genes (rDNA) stained by C-banding. The presence of an hsr, which is a highly amplified rDNA, may explain the molecular diversity of coral rDNA. FISH visualized and demonstrated the presence of a telomere motif (TTA GGG)n in this coral using a human telomere probe. Further- more, we isolated a specific FISH marker (312 bp) designated PC-T1, which was located near the centromere of chromosome 11. -
Spawning Behaviour in Platygyra Daedalea Off South Africa
Galaxea, Journal of Coral Reef Studies 15: 13-14(2013) Photogallery Spawning behaviour in Platygyra daedalea off South Africa L.M. MASSÉ1, 2*, P. CHABANET2, and M.H. SCHLEYER1 1 Oceanographic Research Institute (ORI), PO Box 10712, Marine Parade, 4056 Durban, South Africa 2 Research Institute for Development (IRD), CoRéUs, 2 rue Joseph Wetzell, 97495 Sainte Clotilde Cedex, La Réunion * Corresponding author: L.M. Massé Email: [email protected] Communicated by Saki Harii (Ecology Editor) Keywords spawning, Platygyra daedalea, South Africa, high latitude, fecundity Coral spawning has never been observed in South Africa at the southern most limit of scleractinian distribution along the East African Coast. Corals in the region are exposed to low temperatures (summer means of 26℃) and turbulent conditions (Schleyer et al. 2008), which may influence their spawning. Visiting the reefs at night is difficult, so 10 colonies ofPlatygyra daedalea (Ellis and Solander 1986) were collected on Twomile Reef (27°31′376″S, 32°41′181″E) a few days before the full moon of February 2012 (07/02/12) and placed in openwater aquaria. The date of spawning in P. daedalea off South Africa was predicted from regular sampling of colo nies from 2010. Spawning occurred over three consecutive nights (full moon +2 to +4 days) in 6-9 colonies at a water temperature of 26℃. The peak activity in spawning was observed at full moon +4 days when 9 colonies spawned synchronously. Field sampling showed that in-situ colo- nies also spawned around these dates. Sperm and egg bundles were released between 19:00 to 22:00, with peak release at 20:30. -

Notable illustrations of this are reef-building corals (Anthozoa), which 15 adapted to shallow, oligotrophic, tropical oceans by exploiting light from the sun and the 16 moon to regulate various aspects of physiology including sexual reproduction, phototaxis and 17 photosymbiosis. Together with the Medusozoa, (including jellyfish), the Anthozoa constitute 18 the ancestral metazoan phylum cnidaria. While light perception in Medusozoa has received 19 attention, the mechanisms of light sensing in Anthozoa remain largely unknown. Cnidaria 20 express two principle groups of light-sensing proteins: opsins and photolyases/cryptochromes. 21 By inspecting the genomic loci encoding these photoreceptors in over 35 cnidarian species, 22 we reveal that Anthozoa have substantially expanded and diversified their photoreceptor 23 repertoire. -

Corals of National Park of American Samoa
Corals of National Park of American Samoa Browse Pictures | List of Species How to use this site. The site is organized by an alphabetical list of scientific names, each name linked to a species list by family. (Lists by common and Samoan names are currently only in development). Thumbnail pictures on the family list pages link to enlarged photos. Or, you can browse pages of illustrations arranged by family. Holding your curser on the image will pop up the species name. Clicking on any plate or family list photo jumps to the enlarged picture. This site is a work in progress, regularly revised as coral reef scientists working at, or visiting, the park share their knowledge and expertise about corals at the park's superb reefs. Visiting scientists frequently preview these images and species lists on-line to maximize their time at the park. Lists and photo identifications are continually appended and revised as researchers comment on the website content. Former park marine biologist, Eva DiDonato, initiated the site--with preliminary coral identifications by Charles Birkeland of the University of Hawaii. Several other park ecologists and visiting scientists continue to add new content and critique the material presented. Safety Cautions. The channels, or awa, draining tide or surge buildup from the park's lagoons carry strong rip currents. Beware of these areas. Currently the park has no search and rescue capability.
