- The phylogenies of some orders of opisthobranchs (Anaspidea and Nudibranchia) based on partial sequences of nuclear 18S rRNA and mitochondrial rrnS, rrnL, and cox1 genes were also published recently.
- However, it should be noted that as with Nudibranchia, there are members of Notaspidea that do not swim and others with different modes of swimming locomotion, such as parapodial waves (not shown).
- Of the four major sub-orders of Nudibranchia, at least two (Dentronotidae, and Doridae) include examples of swimming species.
- The order Pleurobranchoidea was located within Nudibranchia, rendering the latter paraphyletic (opisthobranch intrarelationships will be further analyzed elsewhere).
OriginModern Latin (plural), from Latin nudus 'nude' + branchia.
