Family ANOPLOPHRYIDAE Cépède, 1910

No endoskeleton, apical hooks, or suckers, but area of thigmotactic cilia often present; reproduction without chain formation; body relatively small, ovoid to elongate-ovoid; primarily in terrestrial oligochaetes, though some species presumably from other hosts (e.g., the dubious Orchitophrya was found in sea-star gonads and an Anoplophrya reported from lobster gut).
