The Paxillosida are a large order of sea stars.
Characteristics
Paxillosida adults lack an anus and have no suckers on their tube feet. They do not develop the brachiolaria stage in their early development.[1] They possess marginal plates, and have sessile pedicellariae. They mostly inhabit soft-bottomed environments of sand or mud.[2]
Systematics
Recent analyses suggest Paxillosida may be a sister taxon of Asterina.[1] The order is divided into these families:[3]
family Astropectinidae Gray, 1840
family Ctenodiscidae Sladen, 1889
family Goniopectinidae Verrill, 1889
family Luidiidae Sladen, 1889
family Porcellanasteridae Sladen, 1883
family Pseudarchasteridae
family Radiasteridae Fisher, 1916
