Ciliates are single-celled protozoans that can be recognised by their hairlike cilia.
They use them to propel themselves as well as for feeding. Some species like the well known 'slipper animalcule' Paramecium , have cilia all over. With these they can actually 'walk' over a surface. This picture of a Paramecium shows the basic body plan of a ciliate. On the picture most of the cilia were left off to show the internal organelles, Below the centre of the organism you see the feeding opening.
