Histiobalantium is easy to distinguish from the similar genus Pleuronema by the stiff long cilia which intersperse the dense somatic ciliation because Histiobalantium have cilia distributed over the whole cell whereas at Pleuronema this cilia are confined to the posterior region. The body of Histiobalantium natans is elliptical, with the right side slightly concave and anterior end a little narrower than the posterior. The peristome is deep, equipped with a well-developed undulating membrane. Several micronuclei are attached to the two round macronuclei. The contractile vacuole is located in the posterior half of the body. 55 - 105 microns. From fresh water ponds and lakes. This free-swimming specimen of Histiobalantium natans was collected in freshwater ponds near Konstanz, Germany The contractile vacuole is located in the posterior. 95 microns. Differential interference contrast.

Histiobalantium natans(Claparede & Lachmann, 1858), a large scuticociliate - with long stiff cilia extending outwards from the body surface. This individual has ingested a Trachelomonas. Collected from a freshwater pond near Boise, Idaho.Phase contrast.

Ventral infraciliature of the hymenostome ciliate, Histiobalantium natans (Claparede & Lachmann, 1858). The cell is ovoid to reniform in outline with a broadly rounded posterior. The oval oral aperture is located in the mid-portion of the cell. There is an undulating membrane on the right margin of the peristome curving around the posteriorly located cytostome to form a cup or pouch. There are three adoral membranelles on the left side of the peristome. M1 and M2 are parallel and oriented obliquely to the undulating membrane while membranelle M3 is inclined slightly posteriorly between the posterior ends of M1 and M2 and the undulating membrane, forming a triangle. The somatic ciliature is composed of longitudinal kineties. Longer bristle-like cilia are interspersed with more numerous short cilia. Both pre- and post-oral sutures are present. A long caudal cilium absent. There are three contractile vacuoles. Macronucleus with an irregular shape, usually divided into two parts with several micronuclei. Similar in appearance to Pleuronema which may have long caudal cilia but whose other somatic cilia are of equal length. Stained by the silver carbonate technique (see Foissner, W. Europ. J. Protistol., 27:313-330;1991). Collected from a freshwater pond near Boise, Idaho, february 2005. Brightfield.

Oral infraciliature of the hymenostome ciliate, Histiobalantium natans (Claparede & Lachmann, 1858). The cell is ovoid to reniform in outline with a broadly rounded posterior. The oval oral aperture is located in the mid-portion of the cell. There is an undulating membrane on the right margin of the peristome curving around the posteriorly located cytostome to form a cup or pouch (green arrowhead). There are three adoral membranelles on the left side of the peristome. M1 and M2 are parallel and oriented obliquely to the undulating membrane (yellow and pink arrowheads respectively) while membranelle M3 is inclined slightly posteriorly between the posterior ends of M1 and M2 and the undulating membrane, forming a triangle (light blue arrowhead). The somatic ciliature is composed of longitudinal kineties. Longer bristle-like cilia are interspersed with more numerous short cilia. Both pre- and post-oral sutures are present. A long caudal cilium absent. There are three contractile vacuoles. Macronucleus with an irregular shape, usually divided into two parts with several micronuclei.
