New species of bone-eating worm Osedax from the abyssal South Atlantic Ocean (Annelida, Siboglinidae)
A new species of bone-eating annelid, Osedax braziliensis sp. n., found in a sunken whale carcass at a depth of 4,204 m at the base of the São Paulo Ridge in the South Atlantic Ocean off the Brazilian coast is described. The organism was retrieved using the human-occupied vehicle Shinkai 6500 during...
