Which of the following statements does NOT apply to annelid parasites?

• A. They are leeches.
• B. They may cause nose-bleed in monkeys.
• C. They can be removed by gentle traction with forceps.
• D. They cause infestations known as pediculosis.

Answer: (D)

Annelids are segmented worms, and leeches are the classic example of annelid parasites. Pediculosis, on the other hand, is infestation with lice, which are arthropods (insects), not annelids. So the statement that annelid parasites cause pediculosis does not fit, making it the incorrect option for this question.

The other points fit with annelids: leeches are indeed annelids; they can attach to nasal cavities and cause nosebleeds in monkeys; and they can usually be removed by gentle traction with forceps, sometimes with saline handy to help the leech relax and release.
