Strombus gigas (queen conch) (Bahamas) 7

Strombus gigas Linnaeus, 1758 - queen conch shell from the Bahamas. (apical view)

This species is also known as Eustrombus gigas, Lobatus gigas, and Aliger gigas.

The gastropods (snails & slugs) are a group of molluscs that occupy marine, freshwater, and terrestrial environments. Most gastropods have a calcareous external shell (the snails). Some lack a shell completely, or have reduced internal shells (the slugs & sea slugs & pteropods). Most members of the Gastropoda are marine. Most marine snails are herbivores (algae grazers) or predators/carnivores.

The queen conch, Strombus gigas, is a large gastropod that occupies shallow-water to moderately shallow-water seagrass beds, sandy seafloors, and rubbly seafloors. It occurs in tropical to subtropical areas of the western Atlantic Basin, the Gulf of Mexico, and the Caribbean Sea.

The irregularly-shaped hole near the base of the apex was formed when someone took another conch shell and whacked it against this one. Modern humans harvest the meat of a queen conch by using a machete to crack open the shell and then cut a muscle. This results in large, slit-shaped holes. Early humans used another conch shell to break a conch and access the muscle. Such shells with ~subrounded holes are called "paleoconchs". Some occur cemented in Holocene calcarenite limestones.
