Ptychophorae is a suborder of rhizostome jellyfish, identified in 2013 by Gershwin and Davie.[1]
The word Ptychophorae is said to be derived from the Greek ptychos (fold, leaf, layer) and phoras (bearing), in reference to the hooded rhopalia.[1] The proper word for 'fold' in ancient Greek is however ptyx (πτύξ).[2]
Distinctive features
Ptychophorae are distinguished by the following features:
- The body is globular.
- The oral arms coalesce into a single short, ridged column, without scapulets.
- The rhopalia is hooded, lacking typical pits.
- There are 4 velar lappets per octant.
- There 2 asymmetrical ocular lappets per octant.
- The annular muscles are conspicuous.
- The subgenital ostia are very small and round.
- The stomach is circular and large.
- There are 4 radial canals per octant, proximally unbranched, and fluted, and peripherally coalesced into vast open sinus with patchwork of jelly matrix.
