That is a great question! For a long time scientists thought that only plants could turn sun light into energy using a process called photosynthesis. However, in recent years scientists have found a few animals that can make their own energy from sun light!! Here are a few examples of animals that do photosynthesis:

- Sea slug
- Spotted salamandar
- Oriental hornet
- Pea aphid

You can see pictures of these animals and learn more about how they make their own energy at this cool website:
