Segmented worms have distinct body segments and live in the small intestine of the host

6. The major external parasites
Ticks
Lice
Heel flies

7. Assignment
Research the life cycle for each of the 8 parasites you already looked up
Describe each stage of the life cycle
Find pictures of each stage (no less than larva and adult; try to find eggs and pupa)
Which stage is the most harmful to the animal/host? Why?
