Hexocyclium

Hexocyclium is a genus of mollusks in the family Epitoniidae, also known as the wentletrap snails. This genus is known for its unique shell structure and diverse species.

Taxonomy

The genus Hexocyclium was first described by William Healey Dall in 1892. It belongs to the family Epitoniidae, a group of marine gastropod mollusks known for their high-spired, sculptured shells. The name Hexocyclium is derived from the Greek words hex (six) and kyklos (circle), referring to the six whorls typically found in the shells of these species.

Description

Species within the genus Hexocyclium are characterized by their high-spired, tightly coiled shells, which typically have six whorls. The shells are often white or pale in color, with a glossy surface. The aperture is elongated and narrow, and the outer lip is thin and sharp.

Distribution and habitat

Hexocyclium species are found in various marine environments around the world, from the intertidal zone to deeper waters. They are particularly common in tropical and subtropical regions, where they inhabit coral reefs and sandy substrates.

Ecology

Like other members of the family Epitoniidae, Hexocyclium species are carnivorous, feeding primarily on sea anemones and other cnidarians. They use their radula, a specialized feeding organ, to scrape off pieces of their prey.

Species

There are several recognized species within the genus Hexocyclium, including:

• Hexocyclium mitchellii (Dall, 1892)
• Hexocyclium venustum (Dall, 1892)
• Hexocyclium parvulum (Dall, 1892)
