Body symmetry describes how an animal’s body can be divided into equal parts. Animals show three main types of symmetry.

Key Points

• Asymmetry: No symmetry (e.g., sponges).
• Radial symmetry: Body parts arranged around a central axis (e.g., jellyfish, starfish).
• Bilateral symmetry: Can be divided into two equal halves (e.g., humans, insects, fish).
