Stauromedusae are the stalked jellyfishes. They are the sole living members of the class Staurozoa and belong to the Medusozoa subphylum of Cnidaria. They are unique among medusa jellyfish in that they do not have an alternation of polyp and medusa life cycle phases, but are instead interpreted as an attached medusa stage, with a lifestyle more resembling that of polypoid forms.

Las estauromedusas (Stauromedusae) son un orden de la clase Staurozoa, del filo Cnidaria. Se trata de formas sésiles. La superficie aboral (ver simetría radial), correspondiente a la exumbrela de otras medusas, se prolonga en un tallo gracias al cual se fijan al sustrato, en especial algas y rocas.
