Life cycle: The life cycle of this genus is unknown, but third-stage larvae have been found in snails and fishes, and it is also agreed that snails and fishes are paratenic hosts (Bartlett & Anderson 1985; Moravec et al. 1995). The adults parasitize mainly turtles, less frequently amphibians and fish, and even one species of bird (Baker 1987).
