Phyllidia flava Aradas, 1847 (Mollusca Opisthobranchia), new record for the Azores
Hart, Justin; Wirtz, PeterCervera et al. (2006) listed 113 opisthobranch species from the Azores. Since then, several additional coastal opisthobranchs have been reported from the Azores, e.g. Malaquias et al. (2011), Pedro et al. (2011), Cordeiro et al. (2013). We here report yet another previously unrecorded opisthobranch species from the Azores. The observations were made while SCUBA diving at Pico Island, Azores. Two specimens were ...
Alarm reaction and absence of alarm reaction to simulated predation on conspeci...
Wirtz, Peter; Duarte, JoanaBody fluids released by prey can signal the presence of a nearby predator. Numerous aquatic organisms show alarm responses to body fluids of conspecifics (reviewed by Chivers & Smith 1998, and by Ferrari et al. 2010). For nine sea urchin species, an alarm response to the smell of crushed conspecifics or the smell of extracts of conspecifics has been shown (Snyder & Snyder 1970, Mann et al. 1984, Parker & Shulma...

New records of marine invertebrates from the coast of Senegal
Wirtz, PeterDuring dives at the coast of Senegal, in the vicini-ty of NGor Island, several marine invertebrate species were observed that apparently have not yet been recorded from this area.
Shrimps (Crustacea, Decapoda, Caridea) associated with gorgonians at the coast ...
Wirtz, Peter; Grave, Sammy deSymbioses are common in the marine environment. Some taxa appear to be particularly prone to be involved in associations. Crustaceans probably form more associations with other classes than any other marine animals (Ross 1983), crustacean – cnidarian associations being particularly common (Patton 1967). Gorgonianassociated decapods have been described from both sides of the Atlantic (e.g. Spotte et al. 1994, 19...
Ten new records of marine invertebrates from the Azores
Wirtz, PeterThe sea anemones Telmatactis cricoides (Duchassaign, 1850) and Actinia n. sp., the molluscs Tonna galea Linnaeus, 1758, Vitreolina philippi (de Rayneval & Ponzi, 1854), Melanella n. sp., Phidiana lynceus (de Rayneval & Ponzi, 1854) and Anomia patelliformis (Linnaeus, 1761), the nemertine Baseodiscus delineatus (DelleChiaje, 1825) and the echinoderms Leptosynapta inhaerens (O. F. Müller, 1776) and Stichopus rega...
Thirteen new records of marine invertebrates and two of fishes from Cape Verde ...
Wirtz, PeterThe sea anemones Actinoporus elegans Duchassaing, 1850 and Anthothoe affinis (Johnson, 1861) are new records from Cape Verde Islands. Also new to the marine fauna of Cape Verde are an undescribed mysid species of the genus Heteromysis that lives in association with the polychaete Branchiomma nigromaculata, the shrimp Tulearicoaris neglecta Chace, 1969 that lives in association with the sea urchin Diadema antill...
Atlantic reef fish biogeography and evolution
Floeter, S. R.; Rocha, L. A.; Robertson, D. R.; Joyeux, J. C.; Smith-Vaniz, W. F.; Wirtz, Peter; Edwards, A. J.; Barreiros, João P.; Ferreira, C. E. L.Copyright © 2007 The Authors. ; Journal compilation © 2007 Blackwell Publishing Ltd. ; AIM: To understand why and when areas of endemism (provinces) of the tropical Atlantic Ocean were formed, how they relate to each other, and what processes have contributed to faunal enrichment. RESULTS: Phylogenetic (proportion of sister species) and distributional (number of shared species) patterns are generally concord...
Caprellid (Crustacea) - holothurian (Echinodermata) associations in the Azores
Wirtz, PeterDescreve-se para as águas açoreanas associações entre os caprelídeos Caprella stella e Phtisica marina (já encontrados em associação com estrelas-do-mar nos Açores) e o pepino-do-mar Holothuria tubulosa. Os caprelídeos foram encontrados em grandes grupos (mais que 20 indivíduos) na superfície do pepino-do-mar. Isto é o primeiro registo de uma associação entre caprelídeos e um pepino-do-mar. ; ABSTRACT: Caprell...
