The symmetry exhibited by all vertebrates is bilateral symmetry.
To understand why vertebrates exhibit bilateral symmetry, we first need to understand what bilateral symmetry is. Bilateral symmetry means that an organism can be divided into two equal halves along a single plane. Both halves of the organism are mirror images of each other.
In the case of vertebrates, such as mammals, birds, reptiles, amphibians, and fish, bilateral symmetry is evident in their external body structure. If you were to draw a line down the center of a vertebrate's body, you would notice that the left and right sides are essentially identical or almost identical.
One way to recognize bilateral symmetry in vertebrates is by looking at their appendages. For example, most vertebrates have two eyes, two ears, a nose, and a mouth, which are typically found on both sides of their head. Vertebrates also have bilateral pairs of limbs, such as two arms or wings, and two legs or fins.
Bilateral symmetry in vertebrates is advantageous as it allows for efficient movement and coordination. The symmetric positioning of body parts contributes to balance and streamlined motion.
In conclusion, bilateral symmetry is exhibited by all vertebrates, which means they have a body plan that can be divided into two mirror-image halves along a single plane.
