Histriculus (his-trick-you-lus) is a hypotrich ciliate with cirri forming a row all around the margin and including across the back of the cell. Cell not flexible, by which it is distinguished from the very similar Oxytricha, also not with three long caudal cirri, by which it is distinguished from Stylonychia. With adoral zone of membranelles. Phase contrast.

Histriculus (his-trick-you-lus) is a hypotrich ciliate, which can be distinguished by the distribution of the cirri - the aggregates of cilia used in locomotion - on the ventral side. There is an anterior (top of image) array of membranelles (aggregates of cilia) which are used to collect food - typically algae. Differential interference contrast. Material from Nymph Creek and Nymph Lake, thermal sites within Yellowstone National Park, photograph by Kathy Sheehan and David Patterson.
