POMORY 2007 Department of Biology, University of West Florida, 11000 University Parkway, Pensacola, FL 32514, USA. [email protected] ABSTRACT A key is given for 85 species of ophiuroids from the Gulf of Mexico and Caribbean Sea covering a depth range from the intertidal down to 30 m. Figures highlighting important anatomical features associated with couplets in the key are provided. 2 INTRODUCTION The Caribbean region is one of the major coral reef zoogeographic provinces and a region of intensive human use of marine resources for tourism and fisheries (Aide and Grau, 2004). With the world-wide decline of coral reefs, and deterioration of shallow-water marine habitats in general, ecological and biodiversity studies have become more important than ever before (Bellwood et al., 2004). Ecological and biodiversity studies require identification of collected specimens, often by biologists not specializing in taxonomy, and therefore identification guides easily accessible to a diversity of biologists are necessary. -

Clark*, Terri Souster British Antarctic Survey, Natural Environment Research Council, High Cross, Madingley Road, Cambridge CB3 0ET, UK ABSTRACT: Regeneration of arms in brittle stars is thought to proceed slowly in low temperature environments. Here a survey of natural arm damage and arm regeneration rates is documented in the Antarctic brittle star Ophiura crassa. This relatively small ophiuroid, a detritivore found amongst red macroalgae, displays high levels of natural arm damage and repair. This is largely thought to be due to ice damage in the shallow waters it inhabits. The time scale of arm regener- ation was measured in an aquarium-based 10 mo experiment. There was a delayed regeneration phase of 7 mo before arm growth was detectable in this species. This is 2 mo longer than the longest time previously described, which was in another Antarctic ophiuroid, Ophionotus victo- riae. The subsequent regeneration of arms in O. crassa occurred at a rate of approximately 0.16 mm mo−1. To date, this is the slowest regeneration rate known of any ophiuroid. The confir- mation that such a long delay before arm regeneration occurs in a second Antarctic species pro- vides strong evidence that this phenomenon is yet another characteristic feature of Southern Ocean species, along with deferred maturity, slowed growth and development rates. It is unclear whether delayed initial regeneration phases are adaptations to, or limitations of, low temperature environments. -

Clark, 1911), that was collected from Geoje Island, at a depth of 47 m. The species is characterized by a small disk, covered by numerous fine scales, small radial shields that are wider than long, a small stumpy hook at the distal end of the radial shield, two tooth papilla, two adoral shield spines, 2nd adoral shield spine longer than other, tapered dramatically toward dull tip, five arms with four proximal arm spines, and two tentacle scales. We also obtained a 657 bp sequence from COI gene and the amplified sequence matched the general DNA barcoding region. The NJ and ML phylogenetic analyses revealed A. (A.) digitula as monophyletic in the Amphiura clade. This species is clearly distinguished from other Amphiura species by morphological characteristics and the mitochondrial COI sequence, and thus represents the sixth Amphiura species reported to occur in Korea.

Keywords: Ophiocoma, neotype, taxonomy, Ophiuroidea, Indo-West Pacific, Western Indian Ocean, KwaZulu-Natal. Abstract—This study raises the number of Ophiocoma species recorded in South Africa from four to eight. All species are briefly discussed in terms of taxonomy, geographic distribution and ecology. In addition, the juvenile of O. brevipes, found on the underside of adult Ophiocoma brevipes specimens, is described in detail. A neotype is designated for O. scolopendrina. INTRODUCTION The circumtropical family Ophiocomidae The Indo-Pacific distribution ofOphiocoma holds some of the more dominant and has been dealt with by several authors (e.g. conspicuous ophiuroid species present on Clark & Rowe 1971; Cherbonnier & Guille coral and rocky reefs. The family is rich, with 1978; Rowe & Gates 1995).
