Zootaxa, a New Genus of Soft Coral (Octocorallia: Alcyonacea: Clavulariidae)
Zootaxa 1219: 47–57 (2006) ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ ZOOTAXA 1219 Copyright © 2006 Magnolia Press ISSN 1175-5334 (online edition) A new genus of soft coral (Octocorallia: Alcyonacea: Clavulariidae) from Chile L.P. VAN OFWEGEN1, V. HÄUSSERMANN2 & G. FÖRSTERRA2 1Nationaal Natuurhistorisch Museum, P.O. Box 9517, 2300 RA Leiden, The Netherlands. E-mail: [email protected] 2Universidad Austral de Chile, Departamento de Biología Marina, Campus Isla Teja, Casilla 567, Valdivia, Chile. E-mail: [email protected], [email protected] Abstract Incrustatus comauensis n. gen. & n. sp. (Octocorallia: Clavulariidae) is described from Chile. It occurs in shallow water from Concepción to the southern fjord region. The genus forms stolons on mytilid shells and rocks, or encrusting sheets on Crepidula shells (Gastropoda), polychaete tubes, gorgonians, and other substrata. The sclerites of the new taxon are 8-radiates and derivatives of these. The polyps are unarmed or posses a few irregularly arranged spindles. The new genus is compared with another taxon that forms encrusting sheets or stolons. Key words: Coelenterata, Cnidaria, Octocorallia, Alcyonacea, Clavulariidae, benthos, Incrustatus, new genus, new species, Chile Introduction The shallow water soft coral fauna of the Chilean coast is still almost completely unknown. To date one stoloniferous species has been described from Chile, Clavularia magelhaenica Studer, 1878, from the Straits of Magellan. From 1997 onwards, Verena Häussermann and Günter Försterra investigated the anthozoan fauna of Chile, with a focus on the South Chilean fjord region, and collected many specimens. This soft coral collection includes several undescribed species of Alcyonium, a species of Renilla, and some possible clavulariids, among which was an as yet undescribed new genus that is the subject of this paper. -

Coelenterata: Anthozoa), with Diagnoses of New Taxa
PROC. BIOL. SOC. WASH. 94(3), 1981, pp. 902-947 KEY TO THE GENERA OF OCTOCORALLIA EXCLUSIVE OF PENNATULACEA (COELENTERATA: ANTHOZOA), WITH DIAGNOSES OF NEW TAXA Frederick M. Bayer Abstract.—A serial key to the genera of Octocorallia exclusive of the Pennatulacea is presented. New taxa introduced are Olindagorgia, new genus for Pseudopterogorgia marcgravii Bayer; Nicaule, new genus for N. crucifera, new species; and Lytreia, new genus for Thesea plana Deich- mann. Ideogorgia is proposed as a replacement ñame for Dendrogorgia Simpson, 1910, not Duchassaing, 1870, and Helicogorgia for Hicksonella Simpson, December 1910, not Nutting, May 1910. A revised classification is provided. Introduction The key presented here was an essential outgrowth of work on a general revisión of the octocoral fauna of the western part of the Atlantic Ocean. The far-reaching zoogeographical affinities of this fauna made it impossible in the course of this study to ignore genera from any part of the world, and it soon became clear that many of them require redefinition according to modern taxonomic standards. Therefore, the type-species of as many genera as possible have been examined, often on the basis of original type material, and a fully illustrated generic revisión is in course of preparation as an essential first stage in the redescription of western Atlantic species. The key prepared to accompany this generic review has now reached a stage that would benefit from a broader and more objective testing under practical conditions than is possible in one laboratory. For this reason, and in order to make the results of this long-term study available, even in provisional form, not only to specialists but also to the growing number of ecologists, biochemists, and physiologists interested in octocorals, the key is now pre- sented in condensed form with minimal illustration. -

Approximately 400 octocoral specimens were collected from the Ogasawara Islands by SCUBA diving during 2013–2016 and by dredging surveys by the R/V Koyo of the Tokyo Met- ropolitan Ogasawara Fisheries Center in 2014 as part of the project “Biological Properties of Bio- diversity Hotspots in Japan” at the National Museum of Nature and Science. Here we report on 52 lots of these octocoral specimens that have been identified to 42 species thus far. The specimens include seven species of three genera in two families of Stolonifera, 25 species of ten genera in two families of Alcyoniina, one species of Scleraxonia, and nine species of four genera in three families of Pennatulacea. Among them, three species of Stolonifera: Clavularia cf. durum Hick- son, C. cf. margaritiferae Thomson & Henderson and C. cf. repens Thomson & Henderson, and five species of Alcyoniina: Lobophytum variatum Tixier-Durivault, L. cf. mirabile Tixier- Durivault, Lohowia koosi Alderslade, Sarcophyton cf. boletiforme Tixier-Durivault and Sinularia linnei Ofwegen, are new to Japan. In particular, Lohowia koosi is the first discovery since the orig- inal description from the east coast of Australia. -

Soft Coral Biodiversity and Distribution in East Africa: Gradients, Function and Significance
Proceedings of the 11th International Coral Reef Symposium, Ft. Lauderdale, Florida, 7-11 July 2008 Session number 26 Soft coral biodiversity and distribution in East Africa: Gradients, function and significance M.H. Schleyer1, Y. Benayahu2 1) Oceanographic Research Institute, PO Box 10712, Marine Parade, 4056 Durban, South Africa 2) Department of Zoology, Faculty of Life Science, Tel Aviv University, Tel Aviv 69978, Israel Abstract. Soft corals (Octocorallia: Alcyonacea) constitute important reef benthos in East Africa, yet relatively little is known of their distributional gradients, function or significance. Integrated results of published surveys manifest interesting gradients in their diversity, abundance and apparent function. Reef disturbance may result in them becoming dominant, eliciting an alternative stable state in some coral communities. While certain tropical taxa attenuate from north to south, others attain their highest abundance at high latitude; the latter appears to be related to their ability to tolerate sedimentation and more swell-driven turbulence. Once established, soft corals appear to be persistent and long-lived. A long-term monitoring study has nevertheless revealed that they appear to be vulnerable to climate change. Keywords: Soft corals, Alcyonacea, western Indian Ocean, biodiversity gradients Introduction complexity, the deflected currents in question being Soft corals (Octocorallia: Alyonacea) have been the East Madagascan, East African and Mozambique studied on East African reefs at several localities over Currents. Further complex interactions give rise to the the last 15 years, including Tanzania (Ofwegen and Somali and Agulhas Currents at equatorial and higher Benayahu 1992), Mozambique (Benayahu & Schleyer southern latitudes respectively. 1996; Benayahu et al. 2002) and South Africa (Benayahu 1993; Benayahu & Schleyer 1995, 1996; Materials and Methods Ofwegen and Schleyer 1997; Williams 2000; Species lists providing the distributional patterns Williams and Little 2001). -
Euphyllia Paradivisa :: Biological Information
LISTED CORALS IN THE INDO-PACIFIC Euphyllia paradivisa :: Biological Information MORPHOLOGY Pacific Islands Region Colonies of Euphyllia paradivisa are made up of branching, separate corallites. Polyps have branching tentacles. Color is pale greenish-grey or pink (in rare instances) with lighter tentacle tips. Photos copyright: J.E.N. Veron (left), Douglas Fenner (right) REPRODUCTION Euphyllia paradivisa’s reproductive mode is not known. Other Euphyllia species display a variety of reproductive modes so it is unclear which is most probable of this species. :: Spatial Information GEOGRAPHIC RANGE Based on confrmed observations and strong predictions of occurrence in areas that have not yet been surveyed sufciently, Euphyllia paradivisa is likely distributed mostly in the Coral Triangle area (the Philippines to Timor Leste and east to the Solomon Islands). It is also confrmed to occur in American Samoa.

Response of Fluorescence Morphs of the Mesophotic Coral Euphyllia Paradivisa to Ultra-Violet Radiation
www.nature.com/scientificreports OPEN Response of fuorescence morphs of the mesophotic coral Euphyllia paradivisa to ultra-violet radiation Received: 23 August 2018 Or Ben-Zvi 1,2, Gal Eyal 1,2,3 & Yossi Loya 1 Accepted: 15 March 2019 Euphyllia paradivisa is a strictly mesophotic coral in the reefs of Eilat that displays a striking color Published: xx xx xxxx polymorphism, attributed to fuorescent proteins (FPs). FPs, which are used as visual markers in biomedical research, have been suggested to serve as photoprotectors or as facilitators of photosynthesis in corals due to their ability to transform light. Solar radiation that penetrates the sea includes, among others, both vital photosynthetic active radiation (PAR) and ultra-violet radiation (UVR). Both types, at high intensities, are known to have negative efects on corals, ranging from cellular damage to changes in community structure. In the present study, fuorescence morphs of E. paradivisa were used to investigate UVR response in a mesophotic organism and to examine the phenomenon of fuorescence polymorphism. E. paradivisa, although able to survive in high-light environments, displayed several physiological and behavioral responses that indicated severe light and UVR stress. We suggest that high PAR and UVR are potential drivers behind the absence of this coral from shallow reefs. Moreover, we found no signifcant diferences between the diferent fuorescence morphs’ responses and no evidence of either photoprotection or photosynthesis enhancement. We therefore suggest that FPs in mesophotic corals might have a diferent biological role than that previously hypothesized for shallow corals. Te solar radiation that reaches the earth’s surface includes, among others, ultra-violet radiation (UVR; 280– 400 nm) and photosynthetically active radiation (PAR; 400–700 nm). -

ABSTRACT Background. The corallum is crucial in building coral reefs and in diagnosing systematic relationships in the order Scleractinia. However, molecular phylogenetic analyses revealed a paraphyly in a majority of traditional families and genera among Scleractinia showing that other biological attributes of the coral, such as polyp morphology and reproductive traits, are underutilized. Among scleractinian genera, the Euphyllia, with nine nominal species in the Indo-Pacific region, is one of the groups Submitted 30 May 2017 that await phylogenetic resolution.
