Cephea cyclophora; Print; Cephea is a genus of true jellyfish in the family Cepheidae. They are found in the Indo-Pacific and East Atlantic. They are sometimes called the crown jellyfish; but this can cause confusion with the closely related genus Netrostoma or the distantly related species in the order Coronatae. They are also sometimes called the cauliflower jellyfish because of the cauliflower looking crown on top of the bell.
