- The distribution of Mola alexandrini in the Subtropical Eastern Atlantic, with a note on Mola molaPublication . Wirtz, Peter; Biscoito, Manuelhe presence of the “Bump-head sunfish” Mola alexandrini (Ranzani 1839) is recorded, via photographic evidence, from the Azores, Madeira Island, the Canary Islands, and the Cape Verde Islands. Eastern Atlantic individuals of Mola mola can also have a bump on the head.
- The fishes of St Helena Island, central Atlantic Ocean-new records and an annotated check-listPublication . Brown, Judith; Beard, Annalea; Clingham, Elizabeth; Fricke, Ronald; Henry, Leeann; Wirtz, PeterA check-list of the fishes of St Helena Island is presented. The following species are recorded for the first time from St. Helena Island: Rhincodon typus, Mobula tarapacana, Muraena melanotis, Caranx latus, Seriola rivoliana, Balistes capriscus, Lutjanus jocu, Centropyge aurantonotus, Acanthurus coeruleus, Lepidocybium flavobrunneum, Tetrapturus pfluegeri, Coelorinchus geronimo, Pentaceros richardsoni, Gephyroberyx darwinii, Brotula cf multibarbata, Poromitra crassiceps, Echiostoma barbatum, Malacosteus niger, Pachystomias microdon. Including these nineteen new records there are 189 fish species currently known from St Helena. Three of them appear to be undescribed. Eight species and two subspecies are currently considered endemic to St. Helena Island.
- Phylogenetic relationships of the north-eastern Atlantic and Mediterranean blenniidsPublication . Almada, F.; Almada, V. C.; Guillemaud, T.; Wirtz, PeterThe phylogenetic relationships of 27 north-eastern Atlantic and Mediterranean blennioids are analysed based on a total of 1001 bp from a combined fragment of the 12S and 16S mitochondrial rDNA. The most relevant results with implications in current blenniid taxonomy are: (1) Lipophrys pholis and Lipophrys (= Paralipophrys) trigloides are included in a well-supported clade that by the rule of precedence must be named Lipophrys; (2) the sister species of this clade are not the remaining species of the genus Lipophrys but instead a monotypic genus comprising Cory-phoblennius galerita; (3) the smaller species of Lipophrys were recovered in another well-supported and independent clade, which we propose to be recognized as Microlipophrys; (4) although some authors included the genera Salaria and Lipophrys in a single group we have never recovered such a relationship. Instead, Salaria is more closely related to the genera Scartella and Parablennius; (5) the genus Parablennius, which was never recovered as a monophyletic clade, is very diverse and may include several distinct lineages; (6) the relative position of Aidablennius sphynx casts some doubts on the currently recognized relationships between the different blenniid tribes. Meristic, morphological, behavioural and ecological characters support our results and are also discussed. The possible roles of the tropical West African coast and the Mediterranean in the diversification of blenniids are discussed. (c) 2005 The Linnean Society of London.
- First record of Cobia (Rachycentron canadum) (Pisces: Rachycentridae) at the coast of Madeira Island (NE Atlantic OceanPublication . Wirtz, Peter; Genner, M.; Relvas, C.The Cobia Rachycentron canadum is recorded from Madeira Island for the first time. An individual of this species was encountered and video-documented while SCUBA-diving in about 12 m depth at the south coast of this island.
