Phorcus sauciatus

Phorcus sauciatus is a marine gastropod with a shell that can range in size from 11 mm to 27 mm. The shell is imperforate and has a low conical shape, displaying a highly variable coloration. The ground color is typically greenish, especially on the body whorl, with the spire often appearing purplish. Patterns can include dark green, black, or red oblong spots, or an obscure mottling with reddish tones. The shell features six whorls that are spirally striate or lirate, and the aperture is large and very oblique, with a distinctive black-spotted green edge. This species is found in the Eastern North Atlantic, particularly off the Iberian Peninsula, including mainland Portugal and Galicia, as well as in the Canary Islands, Madeira, and the eastern Azores. It typically inhabits rocky substrates in coastal waters. Divers encountering Phorcus sauciatus may find it clinging to rocks or other hard surfaces. The species is herbivorous, primarily grazing on algae. Breeding habits are not detailed in the sources, but like many gastropods, they may engage in reproductive behaviors typical of marine snails. Observations indicate that this species is recorded at dive sites in its native range, suggesting it is relatively accessible for divers. The conservation status of Phorcus sauciatus is not evaluated in the sources.
