Description
Ruppell's Keyhole Limpet (*Diodora ruppellii*) is a marine gastropod mollusc characterized by its conical, cap-like shell with a distinctive apical opening (keyhole). The shell exhibits strong radial ribs and striking alternating dark and light color bands. It is typically found clinging to hard substrates in intertidal and shallow subtidal zones.
