Coralliophila kalafuti is a species of predatory sea snail, a marine gastropod mollusk in the family Muricidae. Members of this family are commonly known as murex snails or rock snails. Specifically, the genus Coralliophila comprises "coral snails," which are characterized by their specialized biological relationship with coral colonies.
The species was formally described and named by malacologist Edward J. Petuch in 1987. The specific epithet kalafuti honors Thomas Kalafut, who contributed to the study of the region's malacofauna.
Taxonomy and Distribution Taxonomically, Coralliophila kalafuti belongs to the subfamily Coralliophilinae. It is primarily found in the tropical Western Atlantic Ocean, with recorded sightings in the waters surrounding Florida, specifically the Florida Keys, and parts of the Caribbean Sea. It typically inhabits coral reef environments at varying depths, depending on the availability of its host organisms.
Description and Ecology The shell of Coralliophila kalafuti is relatively small and robust, a common trait among muricids. Like other members of its genus, it exhibits a sedentary lifestyle, often found firmly attached to or living in close proximity to host corals (anthozoans).
A notable biological feature of Coralliophila kalafuti, and the genus Coralliophila as a whole, is the absence of a radula—the chitinous ribbon used by most mollusks for scraping or cutting food. Instead, these snails are suctorial predators or parasites that use a specialized proboscis to feed on the tissues and fluids of the corals they inhabit. Their shells often develop sculptures, such as spiral ribs or scales, and their coloration may provide camouflage against the coral substrate to avoid detection by predators.
Conservation and Research As with many marine gastropods reliant on coral reef ecosystems, the distribution and population health of Coralliophila kalafuti are closely tied to the health of its host coral species. While it is recognized in malacological literature and databases such as the World Register of Marine Species (WoRMS), detailed studies regarding its specific population trends or conservation status remain limited.
