The Tonnoidea are a group of often large marine gastropods with particularly large larval shells, reaching diameters up to 5.4 mm, and a well-developed periostracum that extends past the apertural opening during the larval stage (Bandel & Dockery 2012). Members of the Tonnoidea are predators, often feeding on echinoderms. They include the Ficidae, fig shells, a small family of tropical shallow-water or abyssal marine gastropods that take their name from the roughly fig-shaped appearance of their shells. Charonia, the tritons, have fusiform shells that can reach giant sizes with the giant triton C. tritonis growing over half a metre in length.
