The Myodocopida is one of the two orders within the Myodocopa, in turn a subclass of the Ostracoda. The Myodocopida are distinguished by a worm-like seventh limb, and, usually, a rostrum above an incisure (notch) from which the antennae can protrude.{{cite book |author=Louis S. Kornicker |year=1993 |title=Antarctic and Subantarctic Myodocopina (Ostracoda) |publisher=Koeltz Scientific Books |isbn=978-1-878762-46-7}} Unlike other ostracods, many species of the Myodocopida have lateral compound eyes{{cite journal |author=Louis S.

More recently, DNA sequences have been used to investigate the phylogeny of various groups.
