Sepeia

Sepeia is a genus of sea snails, marine gastropod mollusks in the family Buccinidae, commonly known as whelks. These snails are found in marine environments and are characterized by their spiral shells, which are typically elongated and often have a pointed apex. The shell's surface can vary in texture, featuring ridges, knobs, or smooth surfaces depending on the species. The aperture, or opening of the shell, is usually elongated and may have a siphonal canal at its base.

The diet of Sepeia snails typically consists of other invertebrates, and they are often predators or scavengers. They possess a radula, a ribbon-like structure with teeth, which they use to scrape or tear food. Their habitat can range from shallow coastal waters to deeper offshore areas, often found on sandy or muddy substrates.

Reproduction in Sepeia, as with many marine gastropods, involves the laying of eggs, often encased in gelatinous masses or capsules. The larval stage is planktonic, meaning the young snails drift in the ocean currents before settling onto the seabed to develop into adult forms. The exact distribution and specific ecological roles of each species within the Sepeia genus can vary widely, contributing to the biodiversity of marine ecosystems.
