Medusozoa
Belongs within: Cnidaria.Contains: Staurozoa, Cubozoa, Scyphozoa, Limnomedusae, Narcomedusae, Trachymedusae, Halammohydra, Thecata, Capitata, Filifera, Codonophora. The Medusozoa are the clade of cnidarians in which a medusa, whether free or reduced, is the normal sexual adult stage of the life cycle and a polyp (if present) functions as the larval stage (Petersen 1979). Subgroups include the Hydrozoa… Continue reading Medusozoa

Ulmaridae
Belongs within: Scyphozoa. The Ulmaridae are a family of jellyfish with simple or branched radial canals joining a marginal ring canal. Characters (Raskoff & Matsumoto 2004): Gastric cavity with peripherally radiating canals (either simple or branched) which join marginal ring canal. Oral arms either broad and curtain like or narrow and tapering; lips usually with nematocyst-lined papillae… Continue reading Ulmaridae

Codonophora
Belongs within: Medusozoa. The Codonophora are a clade within the siphonophores characterised by the presence of nectosomes, bell-shaped zooids specialised for swimming, and gelatinous shield-like bracts; these latter are lost in some subgroups (Dunn et al. 2005). They have been divided between the Physonectae, with a small apical pneumatophore, and the Calycophorae, lacking a pneumatophore,… Continue reading Codonophora
Lobata
Belongs within: Ctenophora.

Ctenophora
Belongs within: Coelenterata.Contains: Lobata. The Ctenophora, comb jellies, are a group of gelatinous marine animals characterised by bands of cilia (comb rows) running longitudinally down the body. Most ctenophores have eight such bands but some early fossil members of the group possessed greater numbers. One Cambrian group, the Scleroctenophora, possessed a skeleton of eight sclerotised… Continue reading Ctenophora
Myxozoa
Belongs within: Cnidaria.Contains: Platysporina. The Myxozoa are a group of parasitic animals in which the body has become greatly reduced to a small number of cells. They exhibit complex life cycles alternating between aquatic vertebrate and invertebrate (annelid or bryozoan) hosts.

Trilobozoa
Belongs within: Coelenterata.Contains: Anabaritida, Conulata. The Trilobozoa are a group of organisms of uncertain relationships known from the Ediacaran and lower Cambrian, characterised by the presence of three planes of symmetry or by the spiral rotation of three independent arm-like structures (Erwin et al. 2011). These include the Ediacaran Tribrachiomorpha which were benthic, reclining forms… Continue reading Trilobozoa
