Systematics

There is currently no consensus as to the subdivision of the Ophiurina (traditionally, the infraorders have been treated as suborders). It contains the genera Amphiura, Amphipholis, and Ophiacantha. The suborder has been divided into the following recent infraorders and families :Smith, A.B.; Paterson, G.L.J., Ophiuroid phylogeny and higher taxonomy: morphological, molecular and palaeontological perspectives.
