Close-Up of a Tick

I enjoyed this article in the New York Times for the close-up of a tick, which shows that the tick's mouth looks like a ratchet.

I first encountered ticks on my pet cat when I was a boy. Back then, I used to pry them off with pliers, which seemed like the only way to get them off. They were already engorged with blood at that point, and some were half the size of a dime. The cat seemed cooperative and did not appear to mind the procedure, which led me to suspect that the tick emitted some kind of localized anaesthetic.
