Definition
An antenna is a sensory appendage found on the heads of insects, crustaceans, and some other animals. They are primarily used for detecting scents, vibrations, and air currents. Think of them as nature's built-in radar systems. Unlike human senses, antennae provide information about the environment in unique ways. They help animals navigate, find food, and communicate with each other. The structure and function of antennae vary greatly among different species.
