A barb is a type of hook that is designed for things to get caught on. Barbs are found on barbed wire, some fish hooks, some arrows, some plant seeds and some animals have barbed claws or teeth.
A hook that is barbed is usually very difficult to get out of whatever it is stuck into. Barbed seeds are bad for animals, as they can get stuck in the animal's skin or inside their mouths and are very hard to get out, so can cause bad infections.
Bis forBarbed wire
Barbed wire, or barb wire, is a type of wire usually used for fencing that has twists of sharp wire along its length. Barbed wire is most often used on fences that keep livestock like cows and sheep from escaping. The sharp barbs on the wire will hurt anything that tries to climb over it.
Barbed wire is not just used to keep animals in or out. Barbed wire was used extensively during war time to protect soldiers, and is also used around prisons to keep the prisoners in.
