Actinotrophon is a genus of sea snails, marine gastropod mollusks in the subfamily Pagodulinae of the family Muricidae, the murex snails or rock snails.MolluscaBase eds. (2020). MolluscaBase.

Description A group which perhaps deserves distinction is Actinotrophon, based on Boreotrophon actinophorus Dall, 1889 in which with the structure of the thin Borvotrophon with long coronating spines is united as a feature, not elsewhere noted in the genus, of successive canals, so curved that the projecting old ones, recurving from the siphonal fasciole form a whorl of hollow split spines, diverging from a deep umbilical pit, as in some murices. In Murex, however, the siphonal canal is closed and the aperture has a projecting callous margin. Dall, W. H. (1902).
