Life cycle: Species of the genus Gyrinicola infect the gastrointestinal tract of tadpoles of Holarctic and Neotropical anurans (Pryor & Greiner 2004). Tadpoles acquire initial infections by ingesting thick-shelled eggs that are distributed in the environment. Female worms possess two uteri; one uterine horn produces thick-shelled unembryonated eggs used as transmission from tadpole to tadpole and the second uterine horn produces thinshelled eggs used for autoinfection. The development of monodelphic or didelphic condition in female worms, and the reproduction by parthenogenesis or haplodiploidy depends on the duration of the developmental period of the anuran hosts (Adamson 1981a; 1981b).
