Sea snail, scientifically known as Rapana venosa, is a gastropod mollusk belonging to the family Muricidae. This shelled marine organism is a predatory species that primarily feeds on bivalves.【1】 

Taxonomy and General Characteristics

Sea snails belong to the phylum Mollusca and the class Gastropoda. Rapana venosa is classified within the family Muricidae. The species is characterized by its thick, spiral-shaped shell, muscular foot, and advanced predatory capabilities.【2】

Morphology

The body of the sea snail consists of soft tissue enclosed within a hard shell. The shell is composed primarily of calcium carbonate and serves a protective function against environmental conditions. The muscular foot located on the underside enables movement along the seafloor. Size and weight vary depending on age, nutritional status, and habitat.【3】 

Feeding Habits

Sea snails are carnivorous organisms. Their primary prey consists of mussels, oysters, and other bivalve mollusks. During predation, they use a hardened structure called the radula to drill holes into the shells of their prey and consume them with secreted enzymes.【4】 

Distribution and Ecological Impacts

Rapana venosa is a species that has been introduced to seas beyond its native range. It is believed to have spread to various marine ecosystems, particularly the Black Sea, via ship ballast water. This introduction has led to invasive behavior and significant pressure on native bivalve populations.【5】

Regenerative Capacity

Some sea snail species are known to possess regenerative capabilities. Scientific observations have shown that these organisms can regenerate certain lost body parts. This trait has made sea snails an important model organism in biological and regenerative medicine research.【6】 

Economic and Scientific Significance

The sea snail is among the species harvested and exported commercially, giving it economic value within the aquaculture sector. At the same time, its invasive characteristics, feeding behavior, and regenerative capacity make it a frequently studied subject in ecological and biological research.【7】
