''Melongena corona'', common name the Florida crown conch, is a species of sea snail, a marine gastropod mollusk in the family Melongenidae, the crown conches and their allies.
==Description== The shell of this species is extremely variable in terms of the degree of spiny ornamentation. Some shells are much smoother than others. These snails cane as large as about 5 in (12 cm) long, and are mostly dark brown with irregular bands of white or cream. There are small spines on the largest whorl of the smoother forms,; the most spiny forms have several rows of spines. The aperture of the shell can be closed at will with an operculum. This snail is a predator; it eats other mollusks, including scallops.〔(Crowned Conch: Dark Invader ) Retrieved 2011-11-29.〕
