Ribbon jellyfish
Chrysaora sp.
Family Pelagiidae
updated Oct 08

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 under the bell are long, flat and ribbon-like with ruffled edges. The animal may be all white, or have orange or pink tentacles and tinges. Sometimes the edge of the bell has 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.
