2)Radial symmetry: Any plane passing through central axis divides the body into two identical halves. For example: coelenterates, echinoderms.
Bilateral symmetry: Body can be divided into left and right halves by one plane only. For example: insects, chordates.

Hi friend,

Invertebrates do not have a back bone or spinal cord (Example like insects and worms).

Vertebrates have a backbone or a spinal cord.(Example birds and humans).

Hope this helped!!!!!
