Fish hook

A fish hook is a tiny piece of metal that is shaped like a "J". It's something that fish use to catch fish from the water. The fisherman puts a worm or some other type of bait on the hook, and then throws it into the water. The fish see the bait and start swimming towards it, but when they try to eat it, the hook gets stuck in their mouth. This is how the fisherman is able to catch fish!
