Central and South Florida Gastropod Seashell Identification Guide: Melongenas

This guide should serve to teach the public how to identify local Central and South Florida gastropod seashells.

Melongenas

(Family) Melongenidae

Distinguishing Characteristics: The Melongenas have a broad siphonal canal, almost as wide as the aperture.  They often have spines that wind around the shoulders and down the body whorl.

Habitat:  These snails prefer to live on intertidal mudflats near mangroves and can survive in brackish water.

Diet:  This family feeds on oysters, tulip snails, and will scavenge on carrion.

Scientific Name:  Melongena corona

Common Name:  Crown Conch

Distinguishing Characteristics:  Often possess large, partly hollow spines traveling up the body whorl to the shoulders and spire.  Species with missing spines may be the result of a dietary deficiency.  Broad dark brown and white stripes predominate the body.  Maximum size 5 inches.

Interesting Facts:  Also known as the King's Crown or Florida Crown Conch.  Two other forms, Melongena bicolor and Melongena altaspira were recently found to be just variants of Melongena corona.
