Mantle cavity anatomy of Ceratostoma foliatum.
This individual was dredged from 50-80 feet of water
off of Friday Harbor, WA, USA. The shell is the individual from BC illustrated

Removing the animal from the shell and cutting open the mantle we can see the mantle cavity organs - the gills that the snail uses to breathe, some sensory organs etc..
