Introduction
Dolphins are amazing creatures. You will learn wonderful facts in this book and enter the dolphin’s world. Let’s dive in!
We’re not Blind!
Dolphins use echolocation to find their way in the sea, not their eyes. Echolocation are rays that comes from a dolphin’s melon. They also use echolocation to find fish. Echolocation is the most helpful thing a dolphin has. If dolphins did not have echolocation dolphins could not eat. So, now you know echolocation is helpful for dolphins!
On Your Mark…Get Set…GO!
Dolphins swim a lot. They swim miles! Let’s see what they do while they’re at it. Dolphins swim at a speed of 33 or 34 kilometers per hour! Baby dolphins learn to swim when they are first born. They swim in pods and sometimes swim to the shore to play with people. Now you know too much! No more info! Just kidding!
This Looks Like a Job For….Super Dolphin!
Dolphins aren’t just cute and smart, they save lives! Let’s learn about it, shall we? They save lives of stranded and drowning divers. Dolphins get rid of underwater mines. They save people from threatening wildlife (in the water). Other dolphins come for baby dolphins to push them to the surface. So, if you’re drowning in a really deep area, there’s a 50% chance a dolphin will save you.
Nope, not Fish!
Dolphins aren’t fish. They are mammals. Why, you’ll see. Dolphins have lungs, like us. They come up to the surface to breath. Dolphins have a blowhole to exhale water. Dolphins DO NOT have gills. People used to think dolphins were fish. They were wrong!
We’re not Fat!
Dolphins have blubber to keep them warm in cold waters. Let’s find out why. Dolphins migrate from warm, tropical waters to icy, cold waters. They stay in these icy cold waters for a long, long time. Blubber is not very helpful in warm waters. But Blubber is very, very helpful in cold waters. So, if you are in a super cold pool probably you would mind but a dolphin wouldn’t!
