Lesson plan
Osedax
Osedax is a genus of siboglinid polychaetes, commonly called snot worms, bone-eating worms, or zombie worms. Osedax is Latin for 'bone devourer' , derived from the worms' unique ecological niche of bone-boring. Osedax settle on a bone, then secrete an acid through specialized root tissues to dissolve the bone's external layers in order to access the lipids within. Osedax act as ecosystem engineers, enhancing the biodiversity of bones they inhabit by increasing their structural complexity, allowing microfauna to inhabit otherwise inaccessible regions of the internal bone. Scientists from the Monterey Bay Aquarium Research Institute using the submarine ROV Tiburon first discovered the genus in Monterey Bay, California, in February 2002. The worms were found living on the bones of a decaying gray whale in the Monterey Canyon, at a depth of .
