Trophon

Trophon geversianum, copyright Femorale.

Belongs within: Muricidae.

Trophon is a genus of marine gastropods found mostly in deepish boreal waters (Oldroyd 1927). The type species T. geversianum is found around the southern coast of South America where it is harvested for food. The operculum is subtetragonal in T. geversianum but oval in members of the subgenus Trophonopsis.

Characters (from Oldroyd 1927): Shell rather strong, fusiform, spire produced, whorls rough, with lamellar varices, their interstices often lirally sulcated; mouth produced below into narrow canal; no teeth or plaits on pillar lip. Operculum corneous, unguicular; nucleus terminal.
