Answer:
Liver flukes employ both sexual and asexual reproduction.
Explanation:
- The parasitic fluke passes from the egg to its first host, the first larva, at the free-swimming, ciliated miracidium stage.
- A sporocyst develops from a miracidium. The sporocyst produces rediae, a larval form with an oral sucker that transforms into cercaria, which has a tapering head and enormous penetration glands.
- The mobile cercaria finds a host and settles there, where it grows into an adult, metacercaria, or metacercaria, depending on the species.
- Liver flukes employ both sexual and asexual reproduction. Adults are hermaphrodites, able to become pregnant on their own as well as through other individuals. Larval sporocysts reproduce asexually, and the rediae that they give birth to do the same. Adults live in the bile ducts of their mammalian hosts.
