The early life history of Scyphozoa with emphasis on Coronatae. Verh.
The holopelagic life cycle of the deep-sea medusa Periphylla periphylla (Scyphozoa, Coronatae).
Class Scyphozoa comprises two lineages: Discomedusae and Coronatae
. The Discomedusae includes the order Semaeostomeae, which is now confirmed to be paraphyletic with respect to the other discomedusan order, Rhizostomeae (Bayha et al., 2010).
Sexual reproduction of Nausithoe aurea (Scyphozoa, Coronatae
However, recent phylogenetic analyses of Cnidaria based on morphology (Marques and Collins, 2004) and molecular data (Collins, 2002) suggest that Stauromedusae is not more closely related to the scyphozoan taxa Coronatae
, Rhizostomeae, and Semaeostomeae (herein united as Scyphozoa, following Marques and Collins, 2004) than it is to Cubozoa or Hydrozoa.
