Bone-eating worms from the Antarctic: the contrasting fate of whale and wood remains on the Southern Ocean seafloor
We report the results from the first experimental study of the fate of whale and wood remains on the Antarctic seafloor. Using a baited free-vehicle lander design, we show that whale-falls in the Antarctic are heavily infested by at least two new species of bone-eating worm, Osedax antarcticus sp. n...
