Unlike their parasitic cousins in the flatworm group the tapeworms and flukes , most turbellarians are free-living, and most are carnivores, eating tiny aquatic invertebrates such as rotifers, small crustaceans, and other worms.

Because they have relatively good sense organs, they make surprisingly efficient predators. Some eat algae. There are many species of turbellarians in Missouri and in the world. It, and three other Missouri cave planarians, are listed in our state as species of conservation concern.

If more research was conducted, they would likely be officially deemed endangered species. Turbellarians are hermaphrodites, meaning that each individual animal possesses both male and female anatomy, and when two turbellarians mate, they inseminate one another. Some species lay eggs encased in round capsules on short stalks. Turbellarians are also famous for their ability to regenerate when cut into pieces, and some species reproduce by splitting their bodies into two of these clones.

Since they breathe through their skin, flatworms are sensitive to water quality and serve as indicators of reduced oxygen and other changes in their habitat. Many people know planarians from watching them regenerate from cut pieces in biology class, a wonderful thing to witness. Ecosystems are based on the tiny plants and animals that form the base of food chains.

Turbellarians are an important link between the tiny, sometimes microscopic animals they eat and their own, larger predators, such as small fish, crayfish, and aquatic insects.
