Leech is a Ducks’ Worst Nightmare
Leeches, which are common in all waterholes and lakes, specialise in sucking blood from larger animals. They bite a hole using three sharp jaws placed in a triangle. Once they have gnawed a hole, they spit specific substances into the wound, which kill the pain, so the victim does not realize that it has been attacked, and have an anti- coagulating effect on the blood, which remains flowing out for as long as possible.
One of the more horrifying of the numerous leech species is the duck leech, which specialises in ducks. When a duck puts its head under the water, the leech swims in through its nostrils or mouth, settling in the nasal cavity or the throat. Finally, there may be so many leeches in the bird’s airways that it suffocates.
