Diversidad, distribución, riqueza y abundancia de condrictios de aguas profundas a través del archipiélago patagónico austral, Cabo de Hornos, Islas Diego Ramírez y el sector norte del paso Drake
This study describes the diversity, distribution, richness, abundance and species composition of the deep sea Chondrichthyes (1,000-2,250 m) of the south Patagonian Archipelago, including Cape Horn, Diego Ramirez Islands and the northern area of the Drake passage, south eastern Pacific Ocean (52°43�...
