Conch-shell
Conch () is a common name of a number of different medium-to-large-sized sea snails. Conch shells typically have a high spire and a noticeable siphonal canal (in other words, the shell comes to a noticeable point at both ends). In North America, a conch is often identified as a queen conch, indigenous to the waters of the Gulf of Mexico and Caribbean. Queen conches are valued for seafood and are also used as fish bait. The group of conches that are sometimes referred to as "true conches" are marine gastropod molluscs in the family Strombidae, specifically in the genus ''Strombus'' and other closely related genera. For example, ''Lobatus gigas'', the queen conch, and ''Laevistrombus canarium'', the dog conch, are true conches. Many other species are also often called "conch", but are not at all closely related to the family Strombidae, including ''Melongena'' species (family Melongenidae) and the horse conch ''Triplofusus papillosus'' (family Fasciolariidae).

Lobatus Gigas
''Aliger gigas,'' originally known as ''Strombus gigas'' or more recently as ''Lobatus gigas'', common name, commonly known as the queen conch, is a species of large sea snail, a marine gastropod mollusc in the family (biology), family of true conches, the Strombidae. This species is one of the largest molluscs native to the Caribbean Sea, and Tropical Atlantic#Marine provinces, tropical northwestern Atlantic, from Bermuda to Brazil, reaching up to in shell length. ''A. gigas'' is closely related to the goliath conch, ''Lobatus goliath'', a species endemic to Brazil, as well as the rooster conch, ''Aliger gallus''. The queen conch is herbivorous. It feeds by browsing for plant and algal material growing in the seagrass beds, and scavenging for decaying plant matter. These large sea snails typically reside in seagrass beds, which are sandy plains covered in swaying sea grass and associated with coral reefs, although the exact habitat of this species varies according to devel ...
