Black-Spined Murex

Class: Gastropoda

Family: Muricidae

Family Description:

The Muricidae includes many large, spectacularly spined and delicately fronded species which commonly found on rocky shores and in estuaries. The common name of `rock shells' is indicative of their habitat among rocks and coral where they frequently become heavily encrusted with marine growth. Muricids are carnivorous, some species obtaining food by drilling a small circular hole in the shell of their prey.
