Siphonophores are one of the least known gelatinous zooplankters in the tropical waters of the Northwestern Atlantic. Most of the regional knowledge about their diversity and distribution is based on surface samples (0–200 m). Siphonophores were collected from oceanic waters off the Mexican Caribbean across an expanded sampling range (0–940 m) during two cruises and were taxonomically examined. A total of 47 siphonophore species were recorded, of these, 14 had not been found in this sector of the Caribbean Sea and 10 represent new records for the Caribbean Basin. The number of species currently known from the western Caribbean is increased from 42 to 56. Some of these species also represent new records for the Northwestern Tropical Atlantic region. The greatest relative increase was observed among species of Lensia, five of which are exclusively deep-living forms dwelling below 300 m. A revised, expanded checklist of the siphonophores of the Western Caribbean is also provided. These results confirm the need of further deep sampling to increase our understanding of Caribbean siphonophore diversity.

In waters of the Northwestern Atlantic pelagic tunicates may contribute significantly to the plankton biomass; however, theregional information on the salp fauna is scarce and limited to restricted sectors. In the Caribbean Sea (CS) and the Gulf ofMexico (GOM) the composition of the salpid fauna is still poorly known and this group remains among the less studiedzooplankton taxa in the Northwestern Tropical Atlantic. A revised checklist of the salp species recorded in the North At-lantic (NA, 0–40° N) is provided herein, including new information from the Western Caribbean. Zooplankton sampleswere collected during two cruises (March 2006, January 2007) within a depth range of 0–941 m. A total of 14 species wererecorded in our samples, including new records for the CS and GOM area (Cyclosalpa bakeri Ritter 1905), for the CS (Cy-closalpa affinis (Chamisso, 1819)), and for the Western Caribbean (Salpa maxima Forskål, 1774). The number of speciesof salps known from the CS and GOM rose to 18. A key for the identification of the species recorded in the region is provided. Studies on the ecological role of salps in several sectors of the NA are scarce and deserve further attention.

We document multiple new records for the deep-water clingfish species Gymnoscyphus ascitus Böhlke and Robins 1970, known previously from only nine specimens collected at the type locality along the Atlantic coast of the Lesser Antillean island of St. Vincent. Five additional specimens, four from the Caribbean Sea (Mexico, Cozumel) and one from the Atlantic (north coast of Cuba), are reported.

ABSTRACT. Introduction: The polychaete fauna inhabiting Chinchorro Bank has been poorly studied and only 35 species have been previously reported. Objective: To examine the taxonomic composition of the Eunicida and Amphinomida associated to dead coral substrates from this coral reef atoll, a Biosphere Reserve located in the southern Mexican Caribbean. Methods: In April 2008, dead coral fragments of the genus Porites were manually collected by SCUBA diving at eight stations between 4-16.2 m depth. Results: A total of 714 individuals belonging to 17 genera and 48 species of the families Amphinomidae, Dorvilleidae, Eunicidae, Lumbrineridae, Oenonidae and Onuphidae were identified. Eunicidae was clearly the more diverse (29 species; 60.4 %) and abundant family (479 individuals; 67.1 %), while the Oenonidae and Onuphidae were represented by only one individual-species each. Thirty-eight species (79.2 %) were new records for Chinchorro Bank, of which 23 species (47.9 %) were newly reported for the Western Caribbean ecoregion. Conclusions: The polychaete fauna recorded showed that the Chinchorro Bank reef is a species-rich habitat that deserves further study; the 48 species from six families identified were similar or even greater than the number of species reported from dead coral environments of other Caribbean Sea regions.

Ecological Differences

The sea anemone Condylactis gigantea is an ecologically important member of the benthic community in coral reefs of the tropical Atlantic, and displays two morphotypes with respect to the color in their tentacular tips: the green tip morphotype and the pink/purple tip morphotype. Although some molecular and ecological differences have been found between these morphotypes, no other morphological distinctions have been reported, and currently both are still considered a single taxonomic species. In the present study, we perform an exploration on the variability in the size of cnidae between these two morphotypes and performed statistical analyses to compare the 10 categories of cnidae from specimens hosted in the Cnidarian Collection of Gulf of Mexico and Mexican Caribbean, of the Universidad Nacional Autónoma de México, which were previously collected in several coral reefs localities of the Yucatán Peninsula. Results reveal no significant variation in cnidae size between the two morphotypes, but significant variations were found within each morphotype. In addition, we update the composition of the cnidom of C. gigantea, and the utility of the size of cnidae to distinguish between morphotypes or closely related species is discussed.

San Andres

The windward reef complex NE and E of San Andrés Island is briefly described in terms of submarine topography, sediments and the distribution of corals and other benthonic organisms. The breaker zone of the San Andrés barrier and other exposed Western Caribbean reefs characteristically exhibits a profuse growth consisting almost exclusively of Millepora. In this respect they are different from most other described West Indian reef localities, where Acropora palmata is the dominating species in this part of the reef. The replacement of Acropora palmata by Millepora is interpreted as an adaptation of the reef crest community to high energy environments due to long swell prevailing at the Western end of the Caribbean Sea. A few short reef sections exposed to the maximum degree of wave energy show conspicuous algal ridges.

Locus Typicus

Mooreonuphis bidentata, a new species of onuphid polychaete, is newly described from the Mexican Caribbean. It was found in dead coral rocks at depths of 2.2 m and can be distinguished from its congeners by having simple filaments branchiae from chaetigers 19–24, as well as bi- and tridentate pseudocompound falcigers and large median simple tridentate hooded hooks in the first four chaetigers. Including M. bidentata sp. nov., the genus Mooreonuphis includes 19 species, which have been exclusively collected on the American coasts, mainly in tropical and temperate waters. From the Caribbean Sea, six species have been recorded. Of these, M. bidentata sp. nov, M. cirrata, M. dangrigae and M. intermedia are the only species having their locus typicus in this tropical region. A taxonomic key is presented for all the species of Mooreonuphis recorded from both sides of the American seas.

We provide a floristic and iconographic reference of benthic marine diatom taxa growing on various artificial substrate plates: fiber-glass, stainless steel, aluminum and copper, afixed to a subtidal beach, as well as of diatoms from the adjacent sediments. The sampling site is located 10 km off the beach of Puerto de Telchac, Yucatan, Mexico. The floristic survey comprises 161 diatom taxa, species and varieties, with six new records for Mexican waters with taxonomic, nomenclatural, and updated bibliographic information for each taxon. Twenty-five taxa were identified solely to genus level. The number of species per substrate was: fiberglass 102, sediments 76, aluminum 51, stainless steel 14, and copper 10. The resulting catalog gathers 267 images, with 137 scanning electron micrographs and 135 light micrographs. Fiber-glass plates showed the highest similarity to natural substrate, at 70% of the total taxa, while copper harbored only 6%.
