Nov 9, 2020 · The crown conch varies in color from brown to purple to white and is carnivorous, eating bivalves, other snails and even some dead organisms. If there are a lot of crown conches in the area, and other species that typically live there are missing, it’s an indication of poor water quality. This can, in turn, affect the oyster and clam populations. Some carnivorous gastropods use the radula for boring through the shells of other animals.
