The magpie perch, magpie morwong or black-striped morwong (Cheilodactylus nigripes), is a morwong, found off southern Australia and northern New Zealand from shallow depths to 250 m. Although traditionally included in the genus Cheilodactylus in family Cheilodactylidae, based on genetic and morpological analyses it belongs in its own genus Pseudogoniistius in family Latridae. Its adult length is between 30 and 50 cm. The species' range in Australian waters extends from Albany in Western Australia to Kiama in New South Wales, including South Australian, Victorian and Tasmanian waters. It lives on rocky reefs, where it feeds upon mollusks, polychaetes and algae. The magpie morwong is able to change its appearance by 'turning off' its central black band almost instantly.
