'''Aliger gigas''', commonly known as the queen conch, is a species of large edible sea snail, a marine gastropod mollusk in the family [[Strombidae]]. This species is native to the tropical northwestern [[Atlantic Ocean]], including the [[Caribbean Sea]] and the [[Gulf of Mexico]].

==Description==

The shell of ''Aliger gigas'' is large and heavy, with a distinctive flared lip. The exterior of the shell is typically pink, orange, or yellow, with a glossy finish. The interior is a striking pink color, which is one of the reasons the shell is highly prized. The shell can grow up to 30 cm in length.

The animal itself has a large foot, a long snout, and two eyestalks. The foot is used for locomotion, allowing the conch to "leap" along the sea floor.

==Habitat==

''Aliger gigas'' is found in warm, shallow waters, typically in seagrass beds and sandy substrates. They are often found at depths ranging from 0.3 to 18 meters. The species is distributed throughout the Caribbean, including the Bahamas, Florida Keys, and the coasts of Central and South America.

==Life Cycle==

The life cycle of ''Aliger gigas'' begins with the laying of eggs in sandy substrates. The eggs hatch into free-swimming larvae, which eventually settle to the bottom and develop into juvenile conchs. Juveniles have a thin shell and are more vulnerable to predators. As they mature, their shells thicken and develop the characteristic flared lip.

==Diet==

''Aliger gigas'' is primarily a herbivore, feeding on algae and seagrass. They use their radula, a toothed tongue-like organ, to scrape food from surfaces.

==Economic Importance==

The queen conch is an important species for local fisheries in the Caribbean. The meat is considered a delicacy and is used in various dishes, such as conch fritters and conch chowder. The shells are also collected for decorative purposes and used in jewelry.

==Conservation==

Due to overfishing and habitat loss, ''Aliger gigas'' populations have declined significantly. The species is listed in Appendix II of the [[CITES]] agreement, which regulates international trade to ensure it does not threaten the species' survival.
