Eulima chyta is a species of small sea snail, a marine gastropod mollusk in the family Eulimidae. It was scientifically described by the malacologist Robert Boog Watson in 1883, based on specimens collected during the H.M.S. Challenger expedition (1873–1876).
Description
The shell of Eulima chyta is small, measuring approximately 0.22 inches (5.6 mm) in length and 0.07 inches (1.8 mm) in width. It is characterized by a smooth, white, and highly polished surface. The shell structure is conical and exhibits a slight curvature toward the apex. It possesses approximately ten flattened whorls and a small, blunt apex. The aperture is oval-shaped, and the outer lip is thin and slightly arched when viewed in profile.
Distribution and Habitat
This species is recorded in the North Atlantic Ocean, specifically in the bathyal zones near the Azores. The type specimens were recovered from a depth of approximately 1,000 fathoms (1,828 meters) in pteropod ooze.
Ecology
As a member of the family Eulimidae, Eulima chyta belongs to a group of gastropods known for their symbiotic relationships with echinoderms (such as sea stars, sea urchins, and sea cucumbers). Most members of this family are ectoparasites or commensals. However, specific host associations or detailed behavioral data for Eulima chyta have not been extensively documented in malacological literature.
Taxonomic Status
The species is recognized in taxonomic databases, including the World Register of Marine Species (WoRMS). While it was originally described under the genus Eulima, some historical records may refer to it under the genus Melanella, though Eulima chyta remains an accepted name.
