in this study, the morphology of a new ciliate belonging to the genus Enchelyodon was investigated. The body is flask-shaped or broadly oval, with a rounded posterior end, a knob-like protrusion of the anterior end of the body, and a size in vivo of 160-195 x 90-130 mum. The somatic ciliature consists of about 89 longitudinal kineties made of monokinetids, three of which have short paired cilia, forming a dorsal brush which extends from the circumoral kinety nearly to the posterior end of the body. The circumoral kinety is composed of 64-96 dikinetids. The macronucleus is ribbon-shaped, long and folded. Many spherical micronuclei are scattered in the cytoplasm. There is a single posterior contractile vacuole. There are rod-shaped extrusomes of two size classes: type 1, 2.6-4.1 mum long, and type II, 51-63 mum long, measured in vivo. in addition, (developing ?) extrusomes with a globular thickening in the middle are evident in silver-impregnated samples.
