General Description

Arms 5, arm rays merge with disc, pentagonal. Six large plates around the edge between arm tips. Plates on oral surface underneath near the mouth (oral plates) usually covered with granules. Usually two colours in alternating bands, as combinations of brown, black, pink, or cream markings. These bands distinguish it from the related Tosia australis which may be similarly coloured but in a star-burst pattern. Centre to arm tip up to 3 cm.


This species was recently separated from a related species, partly based on its reproductive strategy. Spawning occurs in late winter and broods of embryos are protected in depressions under the adult body.


South-eastern Australia.


In the open or under rocks in sub-tidal areas, to depth of 26 m.
