What Is a Fish Swish A trout swims down a stream Zoom A shark chases its ocean meal Nearby glides an eel And a ray skims the sea floor below These animals do not all look alike But they belong to the same animal class They are all fish Are whales fish What about dolphins Q
A No they are not fish Whales and dolphins are actually mammals They live in water but they have to breathe air like we do Sharks are some of the biggest fish in the ocean
This colorful mandarinfish lives in warm water
Fish are alike in many ways They all live in water And they all have a backbone Most fish are also cold-blooded Their bodies match the temperature around them You are warm-blooded Your body temperature stays the same It does not change in the heat or cold
