Animals With Backbones

Many animals have a backbone inside their bodies. Fish, frogs, lizards, birds, and mammals are five groups of animals with backbones.

In the picture

  1. A backbone: a line of small bones along the back
  2. Scales on a fish: small hard plates that cover the skin
  3. Moist skin on a frog: smooth, damp skin
  4. Feathers on a bird: light coverings that keep it warm
