Three s~ ~ ling sites were examined and compared~ f~ging reef, shallow " rubble zone, and outer reef bank. A total of 27 species from 10 families was collected from the three sites. Eleven of these spe­ cies were additions to the reported ophiurdid fauna of Bariados ,,1 and the other islands of the Windward group. On the fringing reef four habitat types were distinguished: 1) sand or limèstone platform/ 2) reef area with greater than 50\ living coral coverage, 3) reet area with less than 50\ living coral . ~overage, and 4) rubble. There was an increase in species d1versity and a decrease in mean ophiuroid density with decreasing spatial heterogeneity. It was observed that the dominant reef ophiuroids vere suspension feeders, rather than bottOM, detritus f~eders. Most brittle-star species were generalfstsjn their choice of substrate. / a&: aSJ .- CI • ......;' .- ~., . .....~ ,> '.\ , '" { RESUME Cette étude porte sur la structure oes communautés d'ophiures ~ryptiques habitant les récifs de coraux: niches écologiques, com­ position des.. espèces, de~sité, diversité.

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.

  • Two New Brittle Star Species of the Genus Ophiothrix
    Caribbean Journal of Science, Vol. 41, No. 3, 583-599, 2005 Copyright 2005 College of Arts and Sciences University of Puerto Rico, Mayagu¨ez Two New Brittle Star Species of the Genus Ophiothrix (Echinodermata: Ophiuroidea: Ophiotrichidae) from Coral Reefs in the Southern Caribbean Sea, with Notes on Their Biology GORDON HENDLER Natural History Museum of Los Angeles County, 900 Exposition Boulevard, Los Angeles, California 90007, U.S.A. [email protected] ABSTRACT.—Two new species, Ophiothrix stri and Ophiothrix cimar, inhabit shallow reef-platforms and slopes in the Southern Caribbean, and occur together at localities in Costa Rica and Panama, nearly to Colombia. What appears to be an undescribed species resembling O. cimar has been reported from eastern Venezuela. In recent years, reefs where the species were previously observed have deteriorated because of environmental degradation. As a consequence, populations of the new species may have been reduced or eradicated. The new species have previously been mistaken for O. angulata, O. brachyactis, and O. lineata. Ophiothrix lineata, O. stri, and O. cimar have in common a suite of morphological features pointing to their systematic affinity, and a similar pigmentation pattern consisting of a thin, dark, medial arm stripe flanked by two pale stripes. Ophiothrix lineata is similar to Indo-Pacific members of the subgenus Placophiothrix and closely resembles Ophiothrix stri. The latter is extremely similar to O. synoecina, from Colombia, and both can live in association with the rock-boring echinoid Echinometra lucunter. Although O. synoecina is a protandric hermaphrodite that reportedly broods its young externally, the new species are gonochoric and do not brood.

    BULLETIN OF MARINE SCIENCE. 32(3): 736-744, 1982 CORAL REEF PAPER AN ASSOCIATION OF A POLYCHAETE, BRANCHIOSYLLIS EXILIS WITH AN OPHIUROID, OPHIOCOMA ECHINATA, IN PANAMA Gordon Hendler and David L. Meyer ABSTRACT On the Caribbean coast of Panama Branchiosyl/is exi/is (Gravier) is associated with Ophio- coma echinata (Lamarck). They have not been found in symbiosis in other localities although both species are widespread. B. exifis was not collected on the ophiuroid species sympatric with O. echinata, but we speculate that it may associate with other hosts elsewhere in its range. Larger ophiuroids are more often infested than smaller specimens. In the majority of infestations a single polychaete is found near the mouth or on the arm on the ventral surface of the ophiuroid. The consistent occurrence of one polychaete per host may be an indication of aggression between individuals of B. exi/is. The polychaete freely enters and leaves the mouth of O. echinata and may steal food captured by the ophiuroid. The incidence of infestation varies at different collecting sites and seasonally at a single locality. It is possible that fluctuations in the incidence of infestation are related to seasonal stress and mortality of B. exilis, or are effected through changes in the density of the host population. Some of the large and relatively sedentary species of the Ophiocomidae act as hosts for associated invertebrates. For example, Indo-Pacific species of Ophio- coma have as associates a tric1ad, pycnogonid, crab, and several species of poly- chaetes (Sloan et aI., 1979). Ophiocoma echinata from Cura<rao harbors an ex- ternal copepod associate (Stock et aI., 1963).

This identification guide is the result of intensive sampling of shallow-water habitats in Bocas del Toro during 2003 and 2004. The guide is designed to aid in identification of a selection of common macroscopic marine invertebrates in the field and includes 95 species of sponges, 43 corals, 35 gorgonians, 16 nem- erteans, 12 sipunculeans, 19 opisthobranchs, 23 echinoderms, and 32 tunicates. Species are included here on the basis on local abundance and the availability of adequate photographs. Taxonomic coverage of some groups such as tunicates and sponges is greater than 70% of species reported from the area, while coverage for some other groups is significantly less and many microscopic phyla are not included.
