Description:

Ancyromonas (ank-ire-owe-moan-ass), small heterotrophic gliding flagellate, with two flagella of which only one (the recurrent flagellum) is evident here. The recurrent flagellum emerges from behind a bulbous lobe at the front of the cell. Not uncommon, but in cooler locations within the thermal Phase contrast.
