Explanation:
Detailed explanation-1: -Parasitic adaptations in liver fluke: Free-swimming larvae have cilia and the cercariae have a flagellum-like tail to help them swim through the aquatic environment and also allow them to reach the plants on which they form a cyst.
Detailed explanation-2: -Life Cycle: The adult flukes deposit fully developed eggs that are passed in the feces . After ingestion by a suitable snail (first intermediate host), the eggs release miracidia, which undergo in the snail several developmental stages (sporocysts, rediae, cercariae ).
