Bilateral symmetry is a type of symmetry where an organism can be divided into two identical halves along a single plane. This means that if you draw a line down the middle of the organism, both sides will mirror each other. Many animals, including humans, fish, and insects, exhibit bilateral symmetry, which helps them move efficiently and interact with their environment. In contrast to other forms of symmetry, such as radial symmetry found in jellyfish, bilateral symmetry allows for a more streamlined body shape. This adaptation is beneficial for locomotion and predation, as it enables organisms to have a distinct front and back, facilitating directional movement and sensory perception.
