Arion cornelius, endemic to Isla Hornos, Tierra del Fuego, Argentina. Horn-like protuberances measuring up to 20mm are presumed to have evolved to fend off the Horned Slug's primary predator, the Thin-skinned Gecko. First discovered by sailors in 1714, the Horned Slug's horns were prized as tooth picks.
