Phorcus
A genus of marine top snails in the family Trochidae.
Phorcus is a genus of marine gastropod mollusks, specifically sea snails, belonging to the subfamily Cantharidinae within the family Trochidae—commonly known as top snails. These snails graze on algae and inhabit the northeastern Atlantic Ocean and the Mediterranean Sea. The genus includes several species, such as *Phorcus articulatus*, *Phorcus atratus*, the extinct †*Phorcus burgadoi* and †*Phorcus gallicophorcus*, as well as *Phorcus lineatus*, *Phorcus mariae*, *Phorcus mutabilis*, *Phorcus punctulatus*, *Phorcus richardi*, *Phorcus sauciatus*, and *Phorcus turbinatus*. Two additional names—*Phorcus margaritaceus* and *Phorcus semigranosus*—are now considered synonyms, the former for *Phorcus richardi* and the latter for *Chlorostoma semigranosum*.

Reader's Guide
The genus Phorcus is significant as a group of marine snails within the Trochidae family, specifically in the subfamily Cantharidinae. According to the article, its species are algal grazers distributed in the northeastern Atlantic Ocean and Mediterranean Sea, indicating an ecological role in intertidal and shallow marine environments. The article provides a list of species, including both extant and fossil forms, which suggests a long evolutionary history in these regions. The inclusion of species brought into synonymy, such as Phorcus margaritaceus and Phorcus semigranosus, reflects taxonomic revisions over time. The references cited, including works by Nordsieck (1974), Vaught (1989), Gofas et al. (2001), and Donald et al. (2012), indicate ongoing scientific study of the genus, particularly regarding phylogenetic relationships and colonization patterns. The article does not provide further details on the significance or legacy beyond these taxonomic and distributional facts.
