Width to 25 cm. Bell surface with fine warts. Four separate mouth-arms, up to 50 cm long, with frilled edges. Bell divided into eight sections (octants); each octant with two notched, tongue-shaped lappets, three main tentacles and a minor one either side (thus five, hence the species name). Bell colour varies from transparent to bluish, pink, yellow or brown, maybe reddish streaked radially. Under-bell may be white; mouth arms pink to yellow with red speckles. Habitat: coastal. Distribution: Indo-Pacific, also Atlantic (Richmond, 1997).
