The family Ctenodiscididae is widespread in the Atlantic to Pacific and Indian Oceans, and Arctic seas. Two genera are known, among which one genus and one species are recorded in Australian waters.

No ctenodiscidids have been recorded in Antarctic waters. Ctenodiscididae are distinguished from other families in the order Paxillosida by the following combination of character states: arms five; tube feet tapered to a point; ampullae single; abactinal surface paxillose; cribriform organs between marginals consisting of superimposed transverse webbed combs of spinelets; actinal surface with transverse rows of ossicles separated by channels covered by webbed spinelets, continuous from cribriform organs to ambulacrals; superambulacral ossicles present; intestinal caecae obsolete, no intestine or anus.
