Narellids

Narellids are a family of marine gastropod mollusks belonging to the order Neogastropoda. They are characterized by their fusiform shells, which are typically elongated and have a distinct, often pointed, spire. The aperture of the narellid shell is usually narrow and elongated, with a prominent siphonal canal. The columella, the central axis of the shell, is often smooth or bears fine lirae.

These snails are exclusively marine and are found in a variety of habitats, from shallow coastal waters to the deep sea. Their diet generally consists of other invertebrates, such as polychaete worms and bivalves, which they capture using a proboscis. Narellids are predatory and possess a radula, a ribbon-like structure with teeth, used for feeding.

The family Narellidae contains several genera and species, and their distribution is widespread across the world's oceans. Some species are relatively common, while others are rare or have limited geographic ranges. Research on narellids is ongoing, with scientists continuing to study their taxonomy, biology, and ecological roles within marine ecosystems. Their shells are sometimes collected by enthusiasts due to their distinctive shapes and patterns.
