Anisonemid phagotrophic euglenid

Hola amigo, esto es lo que me contestaron:

Alastair Simpson:

“ Its an anisonemid phagotrophic euglenid (i.e. Anisonema or 'Dinema').

The cell is unusually full and (perhaps in part for this reason) not exhibiting its gliding motility.

The 'jump' is a characterist shock/direction-changing behaviour of many posterior-flagellum-gliding phagotrophic euglenids.

Why yes, Gordon Lax and I recently wrote a paper on phagtophic euglenids ;)”
