Conjugating ciliates attacked by Coleps

A pair of conjugating Oxytricha of different sizes are suddenly attacked by a Coleps. The smaller Oxitricha is bitten nearly in half, which causes the bonding pair to move their cilia intensively in a frantic effort to escape. Finally the pair separates, and the dwarf and the giant swim off in different directions.
