River Dolphin

River dolphins are like shy explorers who only live in freshwater rivers and some salty, shallow waters called brackish water. They don't travel the big, wide oceans like their cousins. You can find them in rivers in Asia and South America. They love warm places and need rivers that aren't too deep or too fast. It's like they have their own special neighborhoods that other dolphins don't visit!

Some river dolphins are super cool because they can be pink! The Amazon river dolphin can even change its color from grey to pink depending on its mood or how much it exercises. They are smaller than a school bus, with the Amazon river dolphin growing up to 8 feet long. That's about as tall as a small car! They have long noses, called beaks, and special teeth to catch slippery fish.

The water in rivers can be muddy and dark, so river dolphins don't rely much on their eyes, which are very small. Instead, they have amazing hearing and use something called echolocation. They make clicking sounds that bounce off things, like a super-powered sonar! This helps them 'see' in the dark water to find yummy fish to eat. It's like having a built-in GPS and flashlight!

River dolphins are very special, but sadly, they are in danger. Their homes, the rivers, are sometimes polluted or changed by people. This makes it hard for them to find food and safe places to swim. Because they only live in certain rivers, they can't easily move to a new home. We need to protect their river homes so these amazing pink and grey swimmers can keep exploring for a long, long time.
