Interesting Facts
Named the 'fighting conch' because of its aggressive use of its operculum—a sickle-shaped claw—which it uses to jab at predators rather than hiding inside its shell.
Ecological Role
Acts as an important scavenger and detritivore on sandy bottoms, serving as prey for large fish, rays, and sea turtles.
Similar Species
