Define the Bilateral symmetry in animals with an example.

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Bilateral Symmetry**: Bilateral symmetry refers to a type of symmetry in which an organism can be divided into two identical halves along a single plane. This plane is known as the sagittal plane, which runs vertically from the head to the tail.

2. **Characteristics of Bilateral Symmetry**: In organisms exhibiting bilateral symmetry, the left and right sides are mirror images of each other. This means that if you were to draw a line down the middle of the organism, both halves would look the same.

3. **Importance of Bilateral Symmetry**: This type of symmetry is significant as it often correlates with the organism's movement and body organization. Animals with bilateral symmetry typically have a distinct head (cephalization) and a streamlined body, which aids in locomotion.
