Colorized composite image of Didinium nasutum attacking and ingesting a Paramecium. Didinium nasutum is a one-celled, barrel-shaped ciliate characterized by two bands of cilia around its body. It is commonly found in bodies of fresh or brackish water, where it is a voracious predator of its main food source, the much larger unicellular ciliate Paramecium. Didinium attacks and engulfs its prey and digests it within a few hours, ready to hunt again.
