Bipalium species are predatory.Some species prey on earthworms, while others may also feed on mollusks. [10] [11] These flatworms can track their prey.

Cestodes (tapeworms) and trematodes (flukes) have complex life-cycles, with mature stages that live as parasites in the digestive systems of fish or land vertebrates , and intermediate stages that infest secondary hosts.
In North America, where B. adventitium is an introduced species, most earthworms do not immediately recognize the flatworm as a predator.
