Class Kinetofragminophora de Puytorac et al., 1974: Order Haptorida Corliss, 1974 (ref. ID; 4893)

[ref. ID; 2013]
Body shape changeable due to contractility, varies from ovoid to cylindrical to flask-like with long anterior extensible neck region upon which there is a snout-like region consisting of two zones. The apical zone is unciliated and demarks the area which carries the temporary oral aperture when present. The zone nearer the neck is ciliated with long cilia which arise from many short oblique kineties. The posterior end of the cell may be broadly rounded or may narrow to a blunt point. The cell is completely covered by uniform cilia (shorter than those on the snout) which arise from longitudinal or spiral kineties. The somatic kinetosomes may be paired at the anterior end of the body in some species. Macronucleus in 1, 2 or rarely in several parts. Contractile vacuole on posterior body region.

(ref. ID; 1219)
Elongate; highly contractile; two macronuclei; two contractile vacuoles; when dividing, long neck is formed sidewise so that it appears as oblique division (Penard), however, Bovee (1957) noted the division transverse; fresh and salt water. (ref. ID; 1618)
