“…The chemosynthetic assemblages of the REGAB site share many genera and even species with other cold-seep sites in the Atlantic. The alvinocarid shrimp Alvinocaris muricola has been collected in the Gulf of Mexico (Carney, 1994;Cordes et al, 2007), Blake Ridge (Van Dover et al 2003) and Barbados seep aggregations (Olu et al, 1996), and the chirodotid holothurian Chiridota heveva, which seems to be very close to the REGAB species, was first described from the Blake Ridge mussel beds (Pawson and Vance, 2004). The gastropod Provanna sculpta is abundant within Gulf of Mexico mussel beds (Bergquist et al, 2005) and tube-worm aggregations (Bergquist et al, 2003).…”

Detailed surveying with an ROV found that a dense and diverse cold-seep community colonises a giant pockmark located at 3200 m depth, 8 km north from the deep Congo channel. Several types of assemblages, either dominated by Mytilidae and Vesicomyidae bivalves or Siboglinidae polychaetes, are distributed on the 800-m diameter active area. The site is characterised by a most active central zone in a depression with abundant carbonate concretions and high methane fluxes where highdensity clusters of mussels and siboglinids dominate. In contrast, the peripheral zones display large fields of dead and live vesicomyids on soft sediment, with a lower mean density and lower methane concentration in seawater. The associated megafauna includes Alvinocarididae shrimps, echinoids, holothurians of the family Synaptidae, several species of gastropods, two species of galatheids, and Zoarcidae and Ophidiidae fishes. Multivariate analyses of video transect data show that the distribution of these major megafauna species at the pockmark scale is influenced by the habitat heterogeneity due to fluid or gas emission, occurrence of hydrates, substratum variability and by the presence of large symbiont-bearing species. Several assemblages dominated either by mytilids, vesicomyids, or siboglinids have been sampled for megafauna densities and biomass estimations and stable isotope measurements (δ 13 C and δ 15 N) of dominant species and food sources. The highest estimates of megafauna densities have been obtained in mytilid beds. According to their stable isotopes values, non-symbiont-bearing species mainly rely on chemosynthesis-originated carbon, either as primary consumers of chemoautotrophic microorganisms, or at higher trophic level recycling organic matter, or relying on bivalve and tubeworm production. Most of them likely feed on different sources like shrimps, but differences according to habitat have been evidenced. Carbon and nitrogen isotope ratios of galatheids and benthic or benthopelagic fishes captured by trawls at increasing distances from the pockmark provide evidence of the high variability in the proportion of chemosynthesis-originated carbon in their diet, from 15% to 38%, according to the species captured as far as 4 km to the site.

“…With a few notable exceptions, such as apodous holothurians (Smirnov et al 2000, Pawson and Vance 2004 and sea stars (MacAvoy et al 2002(MacAvoy et al , 2005, echinoderms seldom exploit cold seeps and their closely associated biota as food sources (Carney 2010). Of the 52 images of echinoids and holothurians forming the basis of the present study, only two showed echinoids, both of them Gracilechinus alexandri (Danielssen and Koren, 1882) (Fig.…”
