Summary

Description

Haliclystus auricula is a funnel-shaped jellyfish up to 2-2.5 cm high with eight arms radiating from the mouth, connected near the tips by a thin membrane. It is fixed to the substratum by a stalk that is the same length as the bell. Colour varies from grey/green to red/brown. The arms are tipped by clusters of up to 100 short tentacles. The main distinguishing feature of Haliclystus auricula is the presence of kidney-shaped primary tentacles on the membrane margin, between the arms.
