and they can eat small animals. One famous meat-eating plant is the Venus flytrap.

     The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like

the pages of a book. 3. They can open and close very quickly. Inside the leaves. there are three small

hairs. If an insect touches one of the hairs, the leaf closes quickly. The insect cannot get out. In about half
