Descriptive info Diagnosis: ancestrally swimming bikonts, mostly with single major distal striated connexion directly between two centrioles roughly in single plane, more in tetrakonts; ciliary transition zone with radially symmetric transition plate above asymmetric acorn-V filament complex; includes also secondarily surface-associated ciliary gliding phagotrophic euglenoids that retain pellicle from swimming ancestors. Cristae discoid or absent, less often tubular. [details]
