“…variation in oceanographic currents, hard vs. soft substratum and food availability) result in large-scale heterogeneity of the continental margin seafloor (Carpine 1970, Emig 1997, D'Onghia et al 2003. This high habitat heterogeneity plays a major role in the establishment and maintenance of diverse faunal communities (Levin et al 2010), which, to date, are still largely unexplored in the deep Mediterranean Sea (Bienhold et al 2013, Mecho et al 2014.…”

Summary:This study provides a compilation of all available information on deep-sea echinoderms from the middle and lower slopes of the Mediterranean Sea, with the aim of providing a unified source of information on the taxonomy of this group. Previous records of species are updated with new data obtained from 223 trawl hauls conducted in 11 cruises within the northwestern Mediterranean Sea between 800 m and 2845 m depth. Valid names, bathymetric ranges and geographic distributions are given for all species. The new data report, for the first time, the presence of the Atlantic echinoid Gracilechinus elegans (Düben and Koren, 1844) in the Mediterranean Sea. We also report the presence of the endemic holothurians Hedingia mediterranea (Bartolini Baldelli, 1914), dredged only once previously in 1914 in the Tyrrhenian Sea, and Penilpidia ludwigi (von Marenzeller, 1893), known previously only from three samples, two in the Aegean Sea and one in the Balearic Sea. Additionally, the deeper limits of the bathymetric distribution of four species have been expanded: the asteroid Ceramaster grenadensis (Perrier, 1881) to 2845 m; the echinoid Brissopsis lyrifera (Forbes, 1841) to 2250 m; and the holothurians Hedingia mediterranea and Holothuria (Panningothuria) forskali Delle Chiaje, 1823, to 1500 m and 850 m, respectively.Keywords: deep-sea echinoderms; Mediterranean Sea; Gracilechinus elegans; submarine canyons; taxonomy; bathymetric range. Primera cita, redescubrimiento y recopilación de los equinodermos de profundidad en el talud continental medio e inferior del MediterráneoResumen: Este estudio presenta una recopilación de toda la información disponible sobre los equinodermos de profundidad en el talud continental medio e inferior del mar Mediterráneo, con el fin de proporcionar una fuente de información unificada sobre la taxonomía de este grupo. Se han actualizado los registros anteriores mediante nuevos datos provenientes de 223 pescas de arrastre de 11 campañas oceanográficas realizadas en el noroeste Mediterráneo entre 800 y 2845 m de profundidad. Se ha actualizado el nombre de las especies, sus rangos batimétricos y sus distribuciones geográficas. Los nuevos datos presentan, por primera vez, la presencia del equinoideo Atlántico Gracilechinus elegans (Düben and Koren, 1844) en el mar Mediterráneo. También se cita la presencia en el noroeste Mediterráneo de dos especies de holoturias endémicas del Mediterráneo, Hedingia mediterranea (Bartolini Baldelli, 1914)

“…This unique morphological feature, coupled with descriptions provided in the literature (e.g. Monniot & Monniot 1974, 1977aMecho et al 2014), can help with the specific identification of some Octacnemidae species, such as Dicopia antirrhinum Monniot, 1972. Within this family, only D. antirrhinum and Situla lanosa Monniot and Monniot, 1973 have been found so far in the Mediterranean Sea, the former supported by scientific literature (e.g.…”

“…The current knowledge about Mediterranean deepsea fauna is still scarce compared with the fauna in shallower waters, especially concerning the class Ascidiacea. Unlike their shallow-water counterparts, deep-sea ascidians are rather uncommonly found in the Mediterranean Sea (Mecho et al 2014). Visual technologies, such as remotely operated vehicles (ROVs), provide the opportunity to find and observe deep-sea habitats and species.…”

This study reports the in situ observations of a deep-sea ascidian, Dicopia antirrhinum (family Octacnemidae), on the deep seabed off the Aeolian Islands (Tyrrhenian Sea), between 569 and 813 m depth. These observations represent the first record of the species in Italian waters and the second observation in vivo to date. Peculiar macroscopic features are described here and the main differences from other species of the family Octacnemidae are highlighted, in order to allow the future identification of D. antirrhinum through visual technologies such as remotely operated vehicles. A total of 29 specimens were observed, with a maximum density of 0.012 specimens/m 2. The global geographic and bathymetric distribution of D. antirrhinum known so far is also updated and discussed.

“…Most of ascidians are filter feeders (feed on bacteria, phytoplankton and particulate matter) using a mucous net lining inside the branchial sac (Bone et al, 2003). While some deep-water species however are carnivorous (Monniot and Monniot, 1990;Lescano et al, 2011;Tatián et al, 2011;Mecho et al, 2014). All ascidians are hermaphrodites and they generally avoid selffertilization by developing only eggs or only sperm at any point of time (Newlon et al, 2003).…”

The ascidian, Pseudodistomaarborescens, is reported for the first time in the Saudi Arabian water of the Red Sea. It is found to be an important component of the coral reefs at a water depth of 6-13 meter of Janabiyat Island, Doga area (19° 46́ 09.14́ N, 40° 34́ 16.33́E) in December 2014. The species is redescribed and briefly its cytotoxic activity was tested. The anti-proliferative activity of the alkaloid content of Pseudodistoma arborescens has been evaluated against the MCF-7 cell line; showed IC 50 value of 0.70 ± 0.01 mg/L.
