Diphyes dispar, photographed by R. Hopcroft.

Belongs within: Hydrozoa.

The Codonophora is a clade within the siphonophores characterised by the presence of nectosomes, bell-shaped zooids specialised for swimming, and gelatinous shield-like bracts (these latter lost in some subgroups) (Dunn et al. 2005).
