Class 11 Zoology simulations · Animal Kingdom

Body symmetry

Rotate a cutting plane through each animal. Does it give two identical (mirror) halves?

Open the simulation

What to notice

Bilaterally symmetrical animals can be divided into identical left and right halves in only one plane.

Key relation

Radial: any plane through the central axis ; Bilateral: only one plane

Try this

Turn the plane around the starfish. How many angles work?

What you can change

• Animal: choose Sponge, Hydra, Starfish, Earthworm, Frog
• Cutting plane angle: 0 to 180 °
