Where seen? This jellyfish with long trailing ribbon-like oral arms is sometimes seen in numbers on some of our shores. And then not seen again for some time.

Features: Bell about 8-12cm, thin long tentacles around the bell, ribbon-like oral arms 20-50cm long. The oral arms are flat and ribbon-like with ruffled edges. The animal may be all white, or have orange or pink oral arms. Sometimes the edge of the bell has large brown dots.

These animals pack a powerful sting and should not be touched even if they are washed up on the shore. The presence of these animals is why it is important to cover as much skin as possible when wading or swimming in our waters.
