Id for this ciliate (= Urotricha spec.)

[WWWW]

Regularly I see this fast moving ciliate pass by, it then flashes far too quickly through the view. This time it moves a little slower, so now it's on video.
Hopefully sharp enough to determine the name.

Does anyone know the name of this ciliate.



Thanx,
WWWW

It is Urotricha. Mouth is apical w/ nematodesmata, CV in posterior; no somatic cilia at the posterior of the cell. The (rather short) caudal cilium is faint, but visible at a few points in the video (@ 0:13, for instance).

Bruce,

Thank you for the ID and the additional info
