Ciliates get food by sweeping food particles into their gullet.
Ciliates are a group of protozoans of the class Cilliata that are distinguished by the presence of hair-like organelles known as cilia. Most ciliates are heterotrophs; obtains their energy by feeding on smaller organisms or organic matter which they sweep though the mouth pore into their gullet with the aid of modified oral cilia. They use their cilia in feeding, movement, attachment, and sensation.
