Keratella quadrata (Müller, 1786)

Kingdom Animalia, phylum Rotifera, class Monogononta, order Ploima, family Brachionidae.

Depending on the form group, the rear spines are the longest in winter or summer. The animal eats detritus and phytoplankton. The panzer is 200-250 microns large. It is present in standing beta-mesosaprobe waters of all kinds. Wide spread; in this case it was found in a heather fen in the southern part of The Netherlands.

The fast rotating cilia are clearly visible and fairly well defined by the Moticam ProS5 Plus camera.
