epitoniid

Epitoniidae, commonly known as wentletraps, is a family of small, predatory marine gastropod mollusks. They are characterized by their delicate, spiral shells, which are often white or pale in color and possess a distinctive sculpture of axial ribs. These ribs can be smooth, nodulous, or even form sharp, wing-like projections. The shell aperture is typically ovate and lacks an operculum in adult specimens.

Wentletraps are found in all the world's oceans, inhabiting a variety of marine environments from shallow intertidal zones to the deep sea. Many species are associated with specific habitats, such as coral reefs or rocky substrates. Their diet consists primarily of anemones and other cnidarians. They use a specialized proboscis to pierce the tissues of their prey and extract nutrients.

Reproduction in epitoniids generally involves external fertilization, with females laying egg masses. The larval stage is planktonic, contributing to the dispersal of the species. Some species exhibit direct development, bypassing the planktonic larval stage.

The family Epitoniidae is a diverse group, with over 150 described species. They are of interest to malacologists for their unique shell morphology and specialized feeding habits. While not commercially harvested, their shells are sometimes collected by shell enthusiasts due to their intricate beauty.
