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.

[2] The shell of this species is extremely variable in terms of the degree of spiny ornamentation.

[3] M. corona is a significant scavenger and detects food using chemical stimuli.

[5] M. corona also feeds on the common solitary sea squirts Styela plicata and Molgula occidentalis.

[6] Melongena corona is known to be prey of the Florida horse conch Triplofusus giganteus[4] and the whitespotted eagle ray Aetobatus narinari.
