Description:

Kahlilembus attenuatus (SMITH, 1897) FOISSNER, BERGER & KOHMANN, 1994, a hymenostome ciliate. Body shape is elongate and fusiform, the anterior end rounded and the posterior end strongly tapered. The oral apparatus is seen in these images on the organism's left extending posteriorly from the anterior end about one quarter of the body length. 3 adoral membranelles occupy the area just anterior to the cytostome and a prominent flag-like undulating membrane lines the right side of the cytostome. Somatic cilia are arranged in 8 to 10 longitudinal kineties. A spherical macronucleus is located centrally. The contractile vacuole (seen well here) is located just posterior to the midbody. Primarily bactiverous. From freshwater pond near Boise, Idaho. Oblique illumination.
