The Komodo dragon is a deadly lizard. Its body makes a slime full of venom. That’s poison! The slime helps the lizard eat other animals.

The lizard bites into an animal. Venom-filled slime drips out between its teeth. The slime paralyzes the animal. It can’t move. Now the lizard eats its meal.

You can find a slimy animal in your own backyard. It’s a snail! Slime helps snails get around. It comes out from the bottom of their bodies. The slime is sticky. That lets snails climb walls without falling off.
