Clanculus flagellatus

Clanculus flagellatus is a small sea snail with a shell size ranging from 12 mm to 19 mm. The shell is characterized by its conoid shape and umbilicate, granulate structure. It is predominantly white with distinct branching stripes of reddish purple. The whorls of the shell are convex, and the body whorl features eight series of granules, with the base displaying nine close granulose lirae. The aperture is similar to that of Clanculus pharaonius, with a rugose outer lip and a prominent tooth at the edge of the columella. This unique shell structure aids in identification among similar species.  This species is endemic to Australia, found off the coasts of South Australia, Tasmania, Victoria, and Western Australia, typically inhabiting shallow marine environments. It is recorded at depths shallower than 40 m, with 90% of occurrences found below 10 m. The species thrives in rocky substrates and is often found in areas with granulated surfaces where it can graze on algae and organic matter.  Encountering Clanculus flagellatus during a dive can be intriguing, as divers may observe its unique shell patterns and behaviors in its natural habitat. The snail's feeding habits and habitat preferences make it a notable sight for divers exploring the rocky reefs and flats of its distribution area.
