“…Because of their dominance at mid-latitudes most studies have been on fish (Haedrich and Krefft, 1978;Gordon and Duncan, 1985;Haedrich and Merrett, 1990;Koslow, 1993;Fujita et al, 1995;Stefanescu et al, 1992;Moranta et al, 1998). Zonation has also been documented in other megabenthic taxa, such as crustaceans and other benthos (Rowe and Menzies, 1969;Abelló et al, 1988;Fredj and Laubier, 1985;Cartes, 1993;Cartes and Sardà, 1993;Maynou and Cartes, 2000).…”

Information was collected over two seasons on the depth distribution of the deep-water fishes and decapod crustaceans to the southwest of the Balearic Islands. The data were analysed to compare the intensity of faunal change with depth to individual size, measured as mean individual weight, both within and between fish and decapods. The results are discussed on the light of the biological characteristics of the populations studied. We conclude that there are complex distributions of mean weight by depth, determined mainly by trophic aspects and biological adaptations to the oligotrophic environment of the deep Mediterranean.

“…Although the depth-size trends have been studied for decapod crustaceans (Sardà and Cartes, 1993) as well as for fishes (Macpherson and Duarte, 1991;Stefanescu et al, 1992), there has been no comprehensive study of community size structure by depth.…”

“…Even though the deep-sea exploration in the Mediterranean dates back to the end of the eighteenth century (Ryland, 2000), the main knowledge on the deep-sea cartilaginous fish of this basin concerns their taxonomy (Tortonese, 1956). Information on the occurrence, vertical distribution and abundance of chondrichthyes deeper than 1000 metres has been obtained in some areas of the western Mediterranean (Grey, 1956;Carpine, 1970;Allué et al, 1985;Albertelli et al, 1992;Stefanescu et al, 1992aStefanescu et al, , 1992bStefanescu et al, , 1993 and in some areas of the eastern basin (e.g. Isaacs and Schwartzlose, 1975;Gilat and Gelman, 1984;Golani, 1986-87;Klausewitz, 1989;Albertelli et al, 1992;Galil and Goren, 1994;Goren and Galil, 1997;Priede and Bagley, 2000;Jones et al, 2003).…”

SUMMARY: Data collected during the DESEAS survey carried out in three areas of the Mediterranean Sea (Balearic Sea, western and eastern Ionian Sea) were used to describe the distribution and abundance of chondrichthyes species at depths between 600 and 4000 m. A total of 8 chondrichthyes species were recorded, 5 of them in the Balearic Sea, 4 in the western Ionian and 6 in the eastern Ionian. A decrease in abundance with depth was observed in each species with the exception of Centroscymnus coelolepis. The most abundant species were Galeus melastomus and Etmopterus spinax. The depth range of some species was updated. G. melastomus was caught down to 1500 m, exhibiting a smaller-deeper pattern in females, while E. spinax was captured down to 2200 m with a bigger-deeper trend. Mature females of these two sharks were found between 600 and 1500 m. A wide size-range was shown in both species. C. coelolepis was only collected in the Balearic Sea down to 2800 m. The presence of a pregnant female was sampled from a depth of 1500 m. The distribution of the species is discussed in the context of the present knowledge of the Mediterranean ichthyofauna.

“…It is represented in the Mediterranean Sea by two species, Cataetyx alleni (Byrne, 1906) and Cataetyx laticeps Koefoed, 1927(Nielsen, 1986, which are closely associated with depths greater than 1000 m (Stefanescu et al, 1992).…”

“…The species is distributed in the western basin [Catalan Sea between 984 and1851 m (Matallanas, 1983;Stefanescu et al, 1992), Balearic Islands between 700 and 1600 m (Moranta et al, 1998(Moranta et al, , 2004Morales-Nin, 2001), Ligurian Sea between 473 and 750 m (Relini Orsi, 1971, 1974Relini et al, 1986) and Sardinian Channel between 800 and 1420 m (Follesa et al, 2005(Follesa et al, , 2010], and in the eastern basin only in the southern Adriatic Sea between 1074 and 1196 m (Ungaro et al, 2001). Only a few specimens of C. alleni have been collected in the eastern North Atlantic (Porcupine Seabight) between 770 and 1205 m (Merrett et al, 1991).…”

SUMMARY:The reproductive biology of the bathyal viviparous fish Cataetyx alleni was described based on 34 specimens (17 females and 17 males) caught during experimental trawl surveys carried out between 800 and 1700 m depth in the southeastern Sardinian Sea (central-western Mediterranean). Males and females were present at similar size intervals. For the first time, the internal fertilization was demonstrated by the finding of free spermatozoa scattered in the ovarian cavity. Based on macroscopic and histological gonad analysis, mature females were found in summer, autumn and winter, suggesting a long reproductive period. Inseminated females were observed only in November and January, in correspondence with the higher maturity of the males. These results suggest a probable reproductive peak with copulation in autumn-winter. Moreover, histological examination demonstrated that the ovaries of this member of the family Bythitidae had a 'group-synchronous' pattern. No spermatophores in males and embryos in females were observed in the histological sections analysed.
