Our Aim

  • To provide a freely accessible accurate resource describing biodiversity in the Scyphozoa.
  • To distill the information available in the scientific literature, including the latest discoveries, for access by non-specialists.
  • To provide a tool for research, education, and discovery


The Scyphozoan* Wiki is dedicated to integrating and disseminating information describing medusae currently, or previously, recognized as scyphozoans (* i.e. Scyphozoa, the sister taxon Cubozoa, and the enigmatic Staurozoa). It is a venue for scyphozoan biologists of all kinds to present historical and modern knowledge, in simplified form, to non-specialists including aquarists, coastal managers, educators, fisheries biologists, students, and the interested general public, who may all have first hand experience with jellyfishes. We encourage contributions in the hope that The Scyphozoan* Wiki will become a regular repository for, and generator of, new information on this enigmatic group.


The Scyphozoan website, the precursor to The Scyphozoan Wiki, was first published online in April 2003. The 6th, and final html, edition was published in August 2007. The seventh edition marked migration of The Scyphozoan compendium to The Scyphozoan Wiki and archiving of the original site with bibliography, a repository for published datasets, species key, and portal to project websites.

The Scope

The class Scyphozoa: orders Coronatae, Semaeostomeae, Rhizostomeae and all members thereof. Also the Staurozoa (stauromedusae) and Cubozoa (cubomedusae). All attributes of these groups, including their behaviour, biogeography, ecology, and evolution. The inter-relationships between animals, attributes, and environment.
