Description
Size: Max length 25.0 cm WD (male)

Color: Bell color 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.

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).

Dioecious, external fertilization. Undergoes metagenesis, alternation between polyp and medusa generation. Sesile polyps reproduce asexually (i.e. podocyst formation). During spring and summer, undergoes strobilation to give rise to ephyrae, which rapidly grows into dioecious medusae. Hermaphroditism is known but rare. Eggs are shed into gastrovascular cavity. Fertilization takes place either in the cavity or externally and produces free-swimming planula larvae, which settles on firm substrate and eventually develop in polyps.
