Dileptus (die-leapt-us) is a predatory ciliate. There is a body and a neck. The body is elliptical, tapering posteriorly, but extending anteriorly to form the neck. The neck sweeps around to try to find other protozoa or other prey. It is armed with extrusomes which kill the prey and which is then manipulated into food vacuoles by the mouth which is located at the bottom of the neck. The cells have multiple contractile vacuoles (clear structures) and an elongate macronucleus (dark in this image). This image includes an occupied and a vacated cyst. The cysts do not protect against desiccation, but probably are used when there is no food. Phase contrast.

The neck sweeps around to try to find other protozoa or other prey. It is armed with extrusomes which kill the prey and which is then manipulated into food vacuoles by the mouth which is located at the bottom of the neck, and is evident here as a slightly stiffer region just below the fold. This is the circular structure that is visible in this micrograph. The cells have multiple contractile vacuoles (clear structures). Phase contrast.

Dileptus (die-leapt-us) is a predatory ciliate. There is a body and a neck. The body is elliptical, tapering posteriorly, but extending anteriorly to form the neck. The neck sweeps around to try to find other protozoa or other prey. The flexibility of the cells is illustrated here. It is armed with extrusomes which kill the prey and which is then manipulated into food vacuoles by the mouth which is located at the bottom of the neck. The cells have multiple contractile vacuoles (clear structures) and an elongate macronucleus (dark in this image). Phase contrast.

Portrait of Dileptus, large haptorid ciliate with long very flexible proboscis - directed to the right, which the organism casts about as part of its feeding behaviour. The oval cytostome is located at the junction of body and proboscis. Densely packed toxicysts line the ventral surface of the proboscis. The cell is pointed posteriorly. Multiple small contractile vacuoles along dorsum. From aquaculture pond at koi farm near Boise, Idaho. Brightfield.

Predatory ciliate, the snout (to the right) sweeps around and if prey are encountered toxic extrusomes are discharged. The mouth is at the base of the snout. The body is evenly ciliates. Phase contrast microscopy.
