Odontodactylus scyllarus, commonly known as the peacock mantis shrimp, harlequin mantis shrimp, painted mantis shrimp, clown mantis shrimp, rainbow mantis shrimp, peacock odontodactyl, thumb splitter, or simply mantis shrimp, is a large odontodactylid stomatopod native to the epipelagic seabed across the Indo-Pacific, ranging from the Marianas to East Africa, and as far South as Northern KwaZulu Natal in South Africa. It is one of roughly 480 species of mantis shrimp, which are well known for their raptorial claws, exceptional vision, and their unique way of interacting with other marine species. In the marine aquarium trade, it is both prized for its attractiveness and considered by others to be a dangerous pest.
