💡 Fun Facts
- Fish have a special sense called a 'lateral line' running down their sides, which lets them feel movement and vibrations in the water.
- Frogs don't need to drink water—they absorb it directly through a special patch of skin on their belly, which makes them very vulnerable to pollution.
- Some tiny creatures, like the freshwater shrimp, are very sensitive to pollution. Scientists can tell how clean a river is just by checking if these creatures are living there.
