In this study, we present descriptions, illustrations, comments, and bathymetric and geographic distributions of the brittle star species related to the estuary region of Camamu Bay, located in the State of Bahia, Brazil. The brittle star fauna lives on biological substrates, sand bottoms, mud and rubble in the Camamu Bay and comprises 12 species divided into five families. Almost all of them are common in the tropical and subtropical fauna of the regions of shallow water. Ophiophragmus filograneus is reported for the first time in Bahia, and nine other species are recorded for the first time in Camamu Bay: Amphipholis januarii, Amphipholis squamata, Ophiophragmus filograneus, Ophiostigma isocanthum, Ophioderma cinerea, Ophioderma januarii, Ophiactis lymani, Ophiactis savignyi and Ophiocoma echinata. The results suggest that the ophiuroid assemblages are strongly affected by marine currents as well as by different kinds of bottom substrate.

“…3A). Conversely, on a redescription of O. pulchellum by Borges & Campos (2011), no such knobs are described. Apparently, the presence of knobs on the centrodorsal plate is variable and thus not diagnostic.…”

“…Remarks: Marthasterias glacialis is highly polymorphic and has a wide geographical distribution, qualities that have resulted in the description of several synonyms, subspecies and varieties. The validity of these subspecies did not reunite consensus as many believed to be ecophenotypic variations associated with specific environmental conditions (depth, e.g., Mortensen 1933b; Tortonese, 1965; latitude, e.g ., A.M. Clark 1951).…”

In more than 150 years of research in the waters surrounding the Azores, several publications on the fauna of echinoderms of the archipelago have been produced, in the form of papers, notes, reports, reviews, and monographs. This work attempts to summarize the present knowledge on this marine group in the Azorean exclusive economic zone (i.e., waters within 200 nautical miles of the archipelago’s shores). A short review of the history of the species’ taxonomy is given, with key references, geographical distribution, ecology, additional notes and, when possible, figures. We herein report 172 species of echinoderms (6 crinoids, 55 ophiuroids, 45 asteroids, 36 holothurians, and 30 echinoids) from the Azores Archipelago, most of them inhabiting deep waters (>200 m). Only 29 shallow-water species were recorded locally (≤50 m depth). In general, the echinoderm species present in the Azores are characterized by a wide geographical distribution in the Atlantic Ocean. Only nine taxa (all deep-water species, >840 m) appear to be restricted to the Azorean waters. Overall, the knowledge of the echinoderm fauna of the Azores is out-dated, with many species last collected in the archipelago over 100 years ago. A recent interest in the Azorean Mid-Atlantic waters has brought oceanographic cruises back to the archipelago, thus providing new opportunities for the renewal of 150 years of echinoderm studies in the area.

Type specimens of 61 species of the bathyal ophiuriod genera Ophiomusium Lyman and Ophiosphalma H.L. Clark are illustrated and their main features outlined, to form a partial catalogue for current and future workers. Thirty-nine species of Ophiomusium and 22 of Ophiosphalma are recognised, based largely on the number of exposed tentacle pores on the basal ventral arm plates. Most of the Ophiosphalma listed here are new combinations from their original genus, Ophiomusium. Ophiomusium sculptum Verrill is a junior subjective synonym of O. acuferum Lyman, and Ophiosphalma fimbriatum (Koehler) is a junior subjective synonym of O. glabrum (Lütken & Mortensen). The subspecies Ophiomusium fimbriatum atlanticum Hertz and Ophiomusium facunda muta Hertz are elevated to full species. Because of their bathyal habitat (<4000 m), representatives of these genera are relatively rare in collections, and it will require fresh material of a range of sizes, for morphological comparison and for DNA analysis, to reliably confirm their taxonomic validity and clarify their relationships.
