Interesting mode of feeding in an amoeba
Posted: Fri Apr 14, 2023 8:29 pm
I saw a very interesting mode of feeding in an unidentified amoeba recently. When I came upon this amoeba, it had an unfortunate ciliate attached to it. The amoeba seemed to be extracting cytoplasm from the ciliate by suction; I don't know any other way to describe it. In the sequence of photos below, you can see the cytoplasm of the ciliate being "pulled" into a food vacuole and pinched off. However, once this is completed, the amoeba doesn't let go of the ciliate but begins to generate a new food vacuole. The movie shows this and follows the last photo in the sequence.
Photos and video were taken with a Canon 1300D camera attached to a Zeiss Photomicroscope III. Objective is a 40x planachromat, optovar at 1.25x, DIC. The photos were taken using flash.
