, Arabic Volute, Alcithoe arabica
Depth: 50 - 100 m

The Arabic Volute, scientifically known as Alcithoe arabica, is a fascinating marine gastropod species that captivates with its distinctive appearance and intriguing lifestyle. Found across various marine environments, the Arabic Volute plays a crucial role in the delicate balance of its ecosystem.

Description & Characteristics

Alcithoe arabica is characterized by its robust, elongated shell, typically reaching a maximum size of around 10 cm. The shell exhibits a beautiful, intricate spiral pattern, with numerous whorls that gradually increase in size towards the aperture. The shell’s color ranges from a light beige to a deep brown, often adorned with intricate markings and patterns. The Arabic Volute’s foot is large and muscular, allowing it to move effectively across the seabed.

Habitat and Occurrence

The Arabic Volute thrives in a variety of marine habitats, including intertidal zones, tidal zones, and muddy grounds. It is particularly abundant in the subtidal, sublittoral, and infralittoral zones, which encompass the deep zone of the oceans from the lower limit of the intertidal zone to the shelf edge at approximately 200 m water depth. This species is commonly found in the neritic zone, a marine environment that extends from the shoreline to the edge of the continental shelf.

Taxonomy

Alcithoe arabica belongs to the Class: Gastropoda, Order: Neogastropoda, and Family: Volutidae. This classification reflects the species’ evolutionary history and its relationships with other gastropods. The family Volutidae, which includes the Arabic Volute, comprises a diverse group of marine snails known for their striking shells and predatory habits.

Feeding

Alcithoe arabica is a carnivorous predator, primarily feeding on clams and other bivalves. It uses its sharp, radula—a ribbon-like structure studded with teeth—to drill through the shells of its prey. The Arabic Volute then injects a paralyzing venom that allows it to consume the soft tissues inside. Its predatory nature highlights its significant role in the marine food web, controlling populations of its prey species.
