The singlespot frogfish Antennarius radiosus (Lophiiformes, Antennariidae), a valid member of the ichthyofauna of the Azores

The big-eyed frogfish Antennarius radiosus Garman, 1896 is confirmed as a valid record for the Azores. A revision of the historical records confirms three valid species of frogfishes from the Azores (A. radiosus, A. nummifer, Histrio histrio). Two species (A. senegalensis, A. pardalis or A. multiocellatus) require confirmation

Marine Fishes of the Azores : annotated checklist and bibliography : a catalogue of the Azorean marine ichthyodiversity

A list of the marine fishes of the Azores is presented. The list is based on a review of the literature combined with an examination of selected specimens available from collections of Azorean fishes deposited in museums, including the collection of fish at the Department of Oceanography and Fisheries of the University of the Azores (Horta). Personal information collected over several years is also incorporated. The geographic area considered is the Economic Exclusive Zone of the Azores. The list is organised in Classes, Orders and Families according to Nelson (1994). The scientific names are, for the most part, those used in Fishes of the North-eastern Atlantic and the Mediterranean (FNAM) (Whitehead et al. 1989), and they are organised in alphabetical order within the families. Clofnam numbers (see Hureau & Monod 1979) are included for reference. Information is given if the species is not cited for the Azores in FNAM. Vernacular names are always both presented in Portuguese (Azorean names) and English. Synonyms, misspellings and misidentifications found in the literature in reference to the occurrence of species in the Azores are also quoted. The 460 species listed, belong to 142 families; 12 species are cited for the first time for the Azores. Details are given for 23 other species cited for the first time for the Azores in the Red Book of Portuguese Vertebrates (ICN 1993). Fifty-four ambiguous and/or exceptional occurrences are included in an appendix. A second appendix contains the remaining corrections to the checklist of fish included in ICN (1993). The paper concludes with a synthesis and an annotated indexed bibliography of the marine fishes of the Azores. Most references are available through the library of the Department of Oceanography and Fisheries of the University of the Azores.The publication of the present work was funded by the Junta Nacional de Investigação Científica e Tecnológica (JNICT)- Lisboa. The research was made possible through grants received from Secretaria Regional da Agricultura e Pescas-Horta (Açores), INVOTAN- Lisboa, Fundação Calouste Gulbenkian- Lisboa, Fundação Luso-Americana para o Desenvolvimento- Lisboa.

Zoantharians (Hexacorallia: Zoantharia) Associated with Cold-Water Corals in the Azores Region: New Species and Associations in the Deep Sea

Zoantharians are a group of cnidarians that are often found in association with marine invertebrates, including corals, in shallow and deep-sea environments. However, little is known about deep-sea zoantharian taxonomy, specificity and nature of their associations with their coral hosts. In this study, analyses of molecular data (mtDNA COI, 16S, and 12S rDNA) coupled with ecological and morphological characteristics were used to examine zoantharian specimens associated with cold-water corals (CWC) at depths between 110 and 800 m from seamounts and island slopes in the Azores region. The zoantharians examined were found living in association with stylasterids, antipatharians and octocorals. From the collected specimens, four new species were identified: (1) Epizoanthus martinsae sp. n. associated with the antipatharian Leiopathes sp.; (2) Parazoanthus aliceae sp. n. associated with the stylasterid Errina dabneyi (Pourtalès, 1871); (3) Zibrowius alberti sp. n. associated with octocorals of the family Primnoidae [Paracalyptrophora josephinae (Lindström, 1877)] and the family Plexauridae (Dentomuricea aff. meteor Grasshoff, 1977); (4) Hurlizoanthus hirondelleae sp. n. associated with the primnoid octocoral Candidella imbricata (Johnson, 1862). In addition, based on newly collected material, morphological and molecular data and phylogenic reconstruction, the zoantharian Isozoanthus primnoidus Carreiro-Silva, Braga-Henriques, Sampaio, de Matos, Porteiro & Ocaña, 2011, associated with the primnoid octocoral Callogorgia verticillata (Pallas, 1766), was reclassified as Zibrowius primnoidus comb. nov. The zoantharians, Z. primnoidus comb. nov., Z. alberti sp. n., and H. hirondelleae sp. n. associated with octocorals showed evidence of a parasitic relationship, where the zoantharian progressively eliminates gorgonian tissue and uses the gorgonian axis for structure and support, and coral sclerites for protection. In contrast, the zoantharian P. aliceae sp. n. associated with the stylasterid E. dabneyi and the zoantharian E. martinsae sp. n. associated with the antipatharian Leiopathes sp., appear to use the coral host only as support with no visible damage to the host. The monophyly of octocoral-associated zoantharians suggests that substrate specificity is tightly linked to the evolution of zoantharians.Zibrowius alberti sp. n. urn:lsid:zoobank.org:act:8E186AD4-CA6E-419B-B46A-4C8D11C757DDHurlizoanthus hirondelleae sp. n. urn:lsid:zoobank.org:act:6737B10E-9E87-4BA0-9559-C22D49863732Parazoanthus aliceae sp.n. urn:lsid:zoobank.org:act:3D3AA61D-E5CC-47DF-94F1-A4A2FF59ABEAEpizoanthus martinsae sp. n. urn:lsid: zoobank.org:act:04686BB5-03D7-4132-B52B-CC89DF8EBFA8urn:lsid:zoobank.org:pub:FED88229-30F9-481F-9155-FF481790AE5

Occurrence of Grammicolepis brachiusculus Poey, 1873 (Pisces: Grammicolepididae) in the Azores Archipelago

Three specimens of Grammicolepis brachiusculus were caught by the commercial bottom hand and longline fisheries off Terceira and Faial Islands, Azores Archipelago. This is the first record of the species for the region, and one of few ever caught in the NE Atlantic

Notes on fauna associated with an opportunistic artificial reef near cold-water corals

This short communication provides a sporadic insight on the importance of a hard three-dimensional structure for deepwater fish near CWC. Fish size and behaviour inside the structure and in the surrounding area are described. Additionally, a list of biofouling macroorganisms found on the structure after one year of deployment is presented

Taxonomic review of selected invertebrate groups collected during the Campaigns of the Prince Albert I of Monaco in the Azorean waters.

In the late 19th and early 20th centuries Prince Albert I of Monaco promoted 13 cruises that sampled the Azorean waters. During those cruises a total of 2624 nominal marine species were reported in the area. This work assembles the biological data provided by these expeditions to the Azores in a geo-referenced database. Faunal lists for seven invertebrate groups (Echiura, Sipuncula, Cephalopoda, Annelida, Brachiopoda, Chaetognatha and Echinodermata) are compiled. The checklist includes 331 nominal species, of which 310 are valid names: 1 echiurid; 11 sipunculids; 32 cephalopods; 130 annelids; 4 brachiopods; 14 chaetognaths; and 118 echinoderms. Eighteen percent are synonyms, 29% of the species were allocated to a different genus, 2.8% were misspellings and corrections due to gender or concordance rules, 0.8% were specific epithets allocated to sub-specific level or vice-versa, the rest were validated directly (without any modification in their nomenclature)

New occurrences of Corallium spp. (Octocorallia, Coralliidae) in the Central Northeast Atlantic

Corallium niobe Bayer, 1964 and Corallium tricolor (Johnson, 1899) are reported as new records from the central Northeast Atlantic. C. niobe was caught in the Azores and C. tricolor on the slope of the Irving Seamount (South Azores Seamounts). The presence of Corallium johnsoni Gray, 1860 in Azorean waters is confirmed. The sub-tropical Macaronesian islands and seamounts appear to be an important hot-spot for Corallium spp. Most colonies have been collected on seamounts and island slopes around Madeira, Canaries, Azores and the Cape Verde archipelagos. In the Azores most of these corals live below the normal depth of commercial fishing operations and are unlikely to be severely impacted by this activity

Peixes marinhos costeiros da ilha de São Tomé (Golfo da Guiné).

Since the early works of Balthazar Osório, at the turn of the century, only few papers have been published on the ichthyofauna of São Tomé island. The papers dealing with these fishes were compilations of previous works or the results of a few scientific expeditions (e.g. "Galathea" and "Calypso"). In this paper, we present the results of several surveys carried out from the island over the last decade, together with an annotated revision of the known bibliography for the area. The result is an inventory of the coastal fish of São Tomé island. Our records (124 species belonging to 59 families) are based on fish captured, photographed or observed whilst diving and also on those landed by local artisanal fishermen. In this paper we report a total of 185 confirmed coastal species and 67 families. Twenty-seven of these are reported for the first time for the area, and three other unidentified species may represent new species to science. The best represented families are Carangidae (14 species), Serranidae (11 species), Gobiidae and Scombridae (8 species each). Despite its proximity to the African Continent, it is clear that these islands harbour a particular fish fauna, including several amphiatlantic species, which, in the eastern Atlantic, occur only around oceanic islands (e.g., Epinephelus ascencionis, Paranthias furcifer, Mulloidychtis martinicus, Bodianus pulchellus, Chromis multilineata, Gnatholepis thomsoni, Melychthis niger). The coastal ichthyodiversity of São Tomé is apparently poorer than that of the adjacent coasts, showing a significant influence of the islands further west, St. Helena and Ascencion
