The teeth of some animals are wedge-shaped. For example, the human front and canine teeth are shaped like wedges. This makes them useful for cutting up pieces of food. The teeth of many predators, such as the wolf, are also wedge-shaped. They penetrate the skin of their prey easily.

The claws of many predator birds, such as the eagle, are also wedge-shaped. They are useful for digging into their prey.

The beaks of many birds are also wedge-shaped. For example, many woodpeckers have wedge-shaped beaks. The black woodpecker (pictured below) uses its beak to peel away tree bark and cut holes in the tree when hunting for insects.
