Description
A sturdy, heavy-bodied gastropod featuring a distinctive row of sharp spines or knobs around the shoulder of the body whorl. The spire is moderately elevated with rounded whorls, terminating in a pinkish protoconch. The surface shows spiral cords and growth lines, and the aperture is wide with a smooth outer lip.

Interesting Facts
Crown conches are voracious carnivores and scavengers, often feeding on oysters, clams, and other mollusks. They are known to be surprisingly active predators in mangrove ecosystems.
Ecological Role
Acts as an important carnivore and scavenger in estuarine food webs, helping control bivalve populations and recycling organic matter.
Similar Species
Melongena bispinosa (Double-spined Crown Conch), which features two rows of spines instead of one.
Beach Finding Tips
Look along muddy bay shores, salt marshes, and mangrove roots during low tide. They are often found partially buried in mud or crawling among seagrass.
