True Tulip Snail

Fasciolaria tulipa

The tulip snail are both scavengers and carnivores. They prey on other live mollusks, including gastropods and bivalves, and even other tulip snails. They scavenge dead or dying marine animals or tissue. The tulip snails in turn are eaten by stingrays, crabs other crustaceans, sea stars, and bony fishes. In addition to withdrawing into their shell  in case of a threat, they can use their muscular "foot" to throw themselves out of danger. The smaller snails were found in 2-3 feet of water and the largest one in about six feet of water.
