DISTRIBUTION:

South Eastern Florida, Southern Gulf of Mexico, the Caribbean sea, Bahamus and Buruda in the intertidal zone up to 200 m depth.

HABITS:

Found in the intertidal zone up to the depth of 200 meters. Velliger stages will consume algae , where us the juveniles and adults after settling to the bottom will feed on detritus and micro algae. The crystalline style will release the digestive enzymes which will digest the carbohydrates.

SPAWNING:

Become sexually mature at the stage of flared lip. Females will spawn several times during summer releasing large quantity of eggs per spawning which will lye on the sea floor. Upon hatching the velleger stage will swim up and drift with the currents for weeks together before settling to the bottom. This process will take place in 3-4 days.

GROWTH:

Reach the marketable size of 1 feet in 3-3.5 years.

USES:

Used for food. It is a subsistence food in some part of the world like in Florida and Caribbean islands. It has got a clam like flavor and is used in chowder, salad and fritters. Shell is used for the making of ornaments. There is a special type of pearl obtained for this. The shell is burned for the lime which is used for the mortar for the buildings. There are reports that the conch has got anti-tumoral properties.

CULTURE:

Due to the very slow growth it is not considered as a good candidate species for aquaculture.
