Allocreadiidae Explained

Allocreadiidae is a family of flatworms belonging to the order Plagiorchiida.^[1] In their adult stage they parasitize teleosts through their digestive system; they can also parasitize other vertebrates in freshwater ecosystems such as frogs, salamanders, and snakes.^[2] Allocreadiidae are distinguished from other Trematoda in the cercarial stage, where the cercaria have both an eye-spot and a stylet. The cercaria of Allocreadiidae also develop in lamellibranchs, whereas many other trematodes develop in gastropods.
