Elephant tusks, giraffe weevil heads, and antelope horns are all examples of animal weapons. These structures are striking, evolve very rapidly, and are often used in communication. I ask: Why are weapons so big and diverse? How do animals deal with the energetic costs of growing, carrying, and fighting with these weapons? How do animals use weapons as signals to avoid costly fights?
