An injured ciliate
The abnormal shape of this ciliate seems to have been caused by a large bite, leaving the organisms weakened and able to move only feebly.
Commentary by Prof. Yuji Tsukii, Hosei University
As the title suggests, this ciliate exhibits a very abnormal shape. It is possible that when the sample was collected, the body might have be injured by sand particles. Therefore it is difficult to say to what genus this ciliate belongs.
