The Apodida is an order of littoral to deep-sea, largely infaunal holothurians. This order comprises three families, 32 genera and about 270 known species, called apodids.
[edit] Characteristics
Members of this order have a circum-oral ring and tentacles, but do not have tube feet or radial canals. The absence of tube feet gives the order its name, Apodida meaning without feet..
