Bilateral Symmetry
1. Limbs and organs are paired.
2. Cephalization is present.
3. The animals body can be divided into two equal halves (i.e., mirror images) by one plane called midsagittal plane.
Examples: Earthworm, fish, frog, human, being, etc.
Radial Symmetry
1. Limbs and organs occur all around the central axis.
2. Cephalization is absent.
3. The animal’s body can be divided into two equal halves by any vertical plane passing through the central axis.
Examples: Hydra, starfish, etc.
