Using computed-tomography to document borings by Osedax mucofloris in whale bone
Chemosynthesis-based communities have existed on whale skeletons for over 35 million years. However little is known about the effects of Osedax boring on the bone taphonomy and ecology of the whale-fall community. In order to evaluate this important process we used micro computed-tomography (CT) to...

Chemosynthesis-based communities have existed on whale skeletons for over 35 million years.
