MouthsYou can tell a lot about an animal by

looking at its mouth. What does it eat?

How does it catch its food? There are many

feeding adaptations that can be seen throughout

the Aquarium: big teeth, flat teeth, and even

no teeth. Look closely at the mouths of these

animals and see what you can discover!
