Abstract/Summary

Rhizostoma octopus is one of the largest jellyfish to inhabit UK waters. It has a smooth and somewhat flattened shaped umbrella (or bell) that can reach 90 cm in diameter. It is generally white or bluish in colour but may be red, brown, or grey. The blue colouration of the ring muscle of the dorsal umbrella can help differentiate it from closely related species. Beneath the umbrella is a manubrium that bears four pairs of oral arms. There are 16 three-winged scapulets at the upper part of these arms. The oral arms are longer than the bell diameter and end with three-winged bulbs that are wider at their end. There are 112 rounded lobes (lappets) around the margin of the umbrella, and the inner veil bears six pairs of velar lappets per octant. There are no marginal tentacles.
