Whale lice are the most common external parasites of the narwhal [Monodon monoceros]. They particularly favor the base of the male narwhal's tusk. Worms are the most common internal parasites. They particularly favor the stomach, and the middle ear.
external influences on phenotype
It depends on whether they are external or internal parasites. External parasites (such as fleas and ticks) can be treated by flea collars or products such as FrontLine Spot-on. These can be purchased from most pet shops or vets. For internal parasites (such as lungworm or heartworm) these may need veterinary diagnosis and treatment depending on the extent of the infestation. Some internal parasites such as heartworm can be lethal if left untreated. Minor infestations can be killed with over-the-counter products.
