Rhizostome jellyfish -
Rhizostoma octopus

Scientific names: Rhizostoma consists of both the Greek words rhiza, meaning root, and stoma, meaning mouth. Octopus is a combination of the Latin word octo, meaning eight, and the Greek word pous, meaning foot.

Other scientific names: In the Mediterranean there is the rhizostome jellyfish Rhizostoma pulmo. The rhizostome jellyfish that are occasionally seen around scandinavian coasts can possibly belong to the same species as the Mediterranean. If so, even the northern European species should be called Rhizostoma pulmo, because this name is older than Rhizostoma octopus.
