The first intermediate host in all of the fluke life cycles are the: - Copepods - Snails - Fish - Water plants correct answer: Snails Once the miracidium emerges from a fluke egg (in fresh water), it searches for the appropriate species of snail to penetrate. The next stage, known as a sporocyst, develops inside the snail. Copepods are the second intermediate host, which houses the infective stage of Paragonimus westermani, the oriental lung fluke. After emerging from the snail, cercar...
