A small ciliate moving delicately

A small ciliate about 30μin length is busily moving here and there. Its cilia are unusually long and thin compared to its body size, which makes its movements appear delicate.

This organism is Cinetochilum margaritaceum.

The organism is frequently found in the soils that include humic water.

It is characterized by a large mouth at the rear end and a few long cilia extending backward.
