Beetle Beetle bodies Sight and smell
Because beetles have no nose, they use their antennae to smell things. Beetles also use their antennae to feel things around them. Some beetles use their antennae to fight other beetles or even to fight larger animals that want to eat them. Beetle antennae do not all look the same. Some antennae are long and thin, while others are short and wide. Thin antennae are called filiform antennae, and antennae that are wide on the end are called clavate antennae.
