This photograph shows a female of an as yet un-named boneworm in the genus Osedax, which has been carefully removed from the whale bone in which it was growing. This worm has green, feathery palps, which extract oxygen from seawater. At its lower end are an ovisac and bulbous "roots," which would normally be embedded in the whale bone.

Most female boneworms have long, graceful "palps" that wave in the ocean currents.

Subtle differences in the tubes and palps of the different types of boneworms, along with differences in the worms' DNA, allow researchers to determine which worms are different species.

This type of boneworm is so small that it is barely visible to the naked eye.

These unusual boneworms live in seafloor sediment and send roots into the sediment, presumably to digest fragments of bone.
