Rhizostome jellyfish
Rhizostome jellyfish are easy to recognize when they wash ashore. Unlike other jellyfish, this animal is round and bluish. It can grow as large as a soccer ball. Rhizostome jellyfish have no tentacles. Their eight oral tentacles are very visible, hanging down from the mouth opening. The tentacles look like cauliflower, which is a common nickmane for this animal in other languages. Humans are not sensitive the sting of this jellyfish.
- Egg predators
- Hyperia galba, foto fitis, sytske dijksen
The shrimp Hyperia galba is often found in rhizostome jellyfish. This shrimp lives underneath the bell and feeds upon the jellyfish's eggs.
- Distribution and habitat
Rhizostome jellyfish are found between the western Baltic Sea down to the Mediterranean Sea. They are very common in the North Sea and often wash ashore in massive numbers, particularly in the autumn.
