Osedax frankpressi is a species of bathypelagic polychaete worm that lives on the seabed and sustains itself on the bones of dead whales.

[3] When seen on a whale carcase, O. frankpressi has a pinkish trunk with a tuft of red and white plumes on the tip, somewhat resembling a flower.

[3] The death of a whale, or any substantial carcase that falls to the seabed, provides an abundant nutritional opportunity for organisms living in the depths and otherwise dependent on marine snow.

Osedax frankpressi is a small worm that speedily colonises the skeleton, sending out root-like threads that force their way into the bone marrow and absorb the nutrients.

[3] This worm has developed an unusual reproductive strategy to suit its circumstances, these being an occasional superabundance of food, in widely scattered locations, appearing at irregular intervals.
