About Conuber conicum (Lamarck, 1822)
Conuber conicum (Lamarck, 1822), originally described under the name Natica tasmanica, has a shell that can grow to over 50 mm in length. The shell has a partially covered umbilicus. It is a thick, depressedly orbicular shell with a short, slightly exsert spire. Its whorls are convex and rounded, and are either smooth, or marked with oblique, dense, very fine striae. The aperture is semilunar and oriented horizontally. The columella is somewhat thin, with a prominent, spirally sulcate callosity. The umbilicus is angularly excavate, with a callosity inside the suture at the aperture. The shell's exterior is pale fulvous or whitish, marked with bands of brownish or orange lines. The base of the shell is white, and the interior is chestnut or fulvous in colour. This species is endemic to Australia, and is found across all Australian states: New South Wales, Queensland, South Australia, Tasmania, Victoria, and Western Australia. It is a carnivorous marine snail that lives on intertidal sand flats, and feeds on small bivalves.
