DOIAbstract
A benthic community constituted by an assemblage of at least four species of deep-sea corals collected in only one trawl carried-out on the summit of the O'Higgins I seamount, central Chile. The corals were collected in only one trawl carried-out during a Chilean-Japanese cruise onboard the R/V" Koyo Maru" in December 29, 2004. Presence of oxygenated and cold Antarctic Intermediate Water (>400 m depth) on the plateau was recorded under of the Equatorial Subsurface Water associated to the oxygen-minimum zone (OMZ, <1 mL O2 L-1). The biogeographic origin of the fauna evidenced a mix of Subantarctic and central Chile continental margin species. The assemblage is represented by two species of anthipatarians (Leiopathes sp. and Chrysopathes s...
