Alcithoe
Alcithoe is a genus of large, predatory sea snails, marine gastropod mollusks in the family Volutidae, the volutes. The name Alcithoe is derived from the name of a Greek nymph, Alcithoe, who, according to mythology, was transformed into an owl. This genus contains two species: Alcithoe arabica and Alcithoe pacifica.
Common Names
The common name for these snails is "volute". Other names sometimes used include "Australian volute" or "New Zealand volute", referring to the geographic location of the species within this genus.
Characteristics
Alcithoe species are large, heavy-shelled snails with a distinctive, elongated, fusiform shape. The shell is typically smooth and glossy, with a pointed spire and a wide, open aperture. The color of the shell can vary depending on the species and individual, but it is often a mottled brown, orange, or cream color. The body of the snail is fleshy and has a large, muscular foot that is used for locomotion.
Alcithoe snails are carnivores and feed on other marine animals, including worms, crustaceans, and other mollusks. They have a radula, a ribbon-like structure in their mouths, that is covered in rows of tiny teeth. These teeth are used to scrape food off of surfaces and tear prey apart.
Environment
Alcithoe snails are found in a variety of marine environments, including:
- Shallow water
- Deep water
- Soft bottom
- Rocky reefs
- Sand and mud
They are typically found in waters that are warm and temperate.
