1. Oral sucker: A specialized structure located at the anterior end of the liver fluke that is used for attachment to the host's tissues.
2. Ventral sucker: Another sucker located on the ventral surface of the liver fluke that aids in attachment to the host.
3. Body covering: The body of a liver fluke is covered in a protective tegument that helps it evade the host's immune system.
4. Reproductive organs: Liver flukes are hermaphroditic, meaning they have both male and female reproductive organs.
5. Digestive system: Liver flukes have a simple digestive system that includes a mouth, pharynx, and intestine for processing food.
6. Excretory system: Liver flukes have a network of excretory canals that help remove waste from their bodies.
7. Nervous system: Liver flukes have a simple nervous system that includes a nerve ring and nerve cords for coordinating movement and sensory perception.
8. Life cycle stages: Liver flukes have complex life cycles that involve multiple stages, including eggs, miracidia, sporocysts, rediae, and cercariae.
9. Anterior and posterior ends: Liver flukes have distinct anterior and posterior ends, with the anterior end typically being narrower and more pointed.
10. Hooks and spines: Some species of liver flukes have hooks or spines on their bodies that help them attach to host tissues.
