Fasciolaria tulipa, common name the true tulip, is a species of large sea snail, a marine gastropod mollusk in the family Fasciolariidae.

This fiercely predatory species occupies a wide geographic area within the Western Atlantic and is known, along with the other Fasciolariids, for the superficial resemblance their shells possess to a closed tulip flower.

[1][3][4][5] This species resides in the benthic zones of bodies of water with a maximum reported depth of 73 meters and are commonly found in seagrass beds and sand flats in marine environments.

[4][6] The tulip shell has a fusiform outline, with an overall smooth surface, and presents fine growth lines, and small denticles on the inner edge of its delicate outer lip.

Today, it is known that Fasciolaria tulipa lives in the Benthic region of the ocean in a temperate habitat around seagrass beds and tidal flats and is larger than its relative: F. hunteria.

In order to evade predation, the tulip snail uses its operculum to seal the aperture after it retracts into its shell when threatened or sense potential hazards.

This snail eats bivalves and various other gastropods including the banded tulip Fasciolaria lilium, and the queen conch Eustrombus gigas.

The female reproductive system consists of ovaries, cement glands located centrally on the foot, and the large pallial oviduct.
