Order

Common name: Rhizostome Jellyfish

Scientific name: Rhizostomeae

Rhizostomeae is an order of jellyfish characterized by the absence of tentacles and a complex, branched oral arm structure. Members of this order, such as the popular aquarium species Cotylorhiza tuberculata, are known for their impressive size and often striking coloration. Rhizostome jellyfish are filter feeders, consuming plankton and small particles from the water column. They are fascinating additions to large public aquariums but are not typically suitable for home reef tanks due to their size and specialized care requirements.
