Cell gliding with two filopodia

Ventricleftida Cavalier-Smith 2011

Strongly flattened oval cell with rigid theca without scales; two unequal cilia emerging subapically, often from apical notch – posterior cilium used for gliding on surfaces; ventral cleft from which branched filose pseudopods emerge for feeding separate from and posterior to ciliary groove unlike Thaumatomonadida and Auranticordis; extrusomes.

Ventrifissura, Verrucomonas.

Photomicrographs of the same cell showing two cilia (arrowed) originating from the fundal region. One pseudopodium (ps) is visible. The granulated mass in the fundus is the nucleus.
