A lazy ciliate

This colorless ciliate seems to have a hard, partially concave surface. It is standing still, slowly moving the long cilia near its mouth. There is no evidence that it is catching any food with this lazy movement.

Commentary by Prof. Yuji Tsukii, Hosei University
This organism cannot be identified even to the genus level because the body was injured and fragmented by sand particles when it was collected. Only the front part remains intact.
