Murex Shell (Jorunna fenebris)
Observed: Koh Chang, December 2015
Observed By: BB Divers
The Muricidae are a family of sea snails that have charecteristic shells with elaborate protective spines protruding from them.
The majority of this family are carnivores that feed on smaller species of shells which they gain access to by boring through the shells and sucking out the soft contents (pause for a shudder!)
