Description:
The Florida crown conch, Melongena corona, is a large, predatory snail that reaches 8 inches.  The shell is heavy and covered by a thick periostracum,   Large, hollow spines,  triangular in cross section, line the shoulders of the body whorls in 1 or more rows.  Color is highly variable, but is generally a dirty tan or brown with spiral bands of brown, purple-brown or dark blue-black.  Sutures between body whorls are indented.  The outer lip is thin and arched, while the siphonal canal is broad and open. 

Habitat:
Florida crown conchs typically inhabit mud or mud/sand areas in the quiet waters of bays and lagoons.  They are often found in association with seagrass beds, mangroves, and oyster reefs in the shallow intertidal zone to depths of 6 feet. 

Range:  
Crown conchs are known from both coasts of Florida, Alabama, the Gulf of Mexico, and Mexico.
