A conoid is found in most species and when present forms complete but truncated cone.

Sexual and asexual reproduction are present in life cycle of all species.

This process of sporogony produces mobile vermiform infectious sporozoites.

Multiple mitotic divisions (schizogony) also occur during merogony of the feeding stages (trophozoites) and during gametogony.

Locomotion of other gametes and any other motile stages is by gliding or body flexion.
