In situ photographs of Osedax on whale (A) and cow (B) bones sampled from the 1820-m locality. Scales are similar as determined from the manipulator claw. The porous whale bone has a high density of worms composed mostly of O. rubiplumus. In contrast, O. rubiplumus and O. nude-palp A sparsely populated the hard surface of the cow bone.
