1. Dolphins Can Swim More Than 20 Miles Per Hour

Shocking right! Those cute little dolphins are also super fast swimmers and have been known to go as fast as 20-25 miles per hour. Sometimes over 30 miles per hour in bursts.

Why? The dolphin’s tail, which is also known as a fluke, acts as wings. Since the flukes are flexible, dolphins can control the stiffness and how fast the tail goes up and down. The quicker it goes, the more speed it creates pushing them through the water.

2. A Group of Dolphins Is Called A Pod

You know how when you have a group of fish it’s called a “school of fish”. Well, with dolphins, a group is known as a “pod”.

3. Dolphins Can Hold Their Breath For Up To 10 Minutes

Dolphins have a blowhole on the top of their head which acts as a flapper. This means when they go underwater, the flapper closes and no water gets into their lungs.

4. They Love To Be Social

Most dolphins love interaction and attention. They also have a good sense of family and keep their babies close to them longer than most animals. That’s why you often see them in a group.

It’s also important to note that because they have such a good sense of family, they know and feel when one is injured and try to help. This was actually one of our favorite dolphin facts for kids!

5. The Orca Is Actually The Largest Dolphin

Before we started studying dolphins and researching different dolphin facts for kids, we didn’t know the Orca was actually a dolphin. We were thinking of it as a whale. According to Whales.org, the Orca is the largest dolphin with the Hector’s dolphin and Franciscana dolphins being the two smallest.

6. They Communicate In Different Ways

Dolphins communicate in more ways than one. When they communicate, it is by clicks, whistles and squeals. You can often hear them chattering back and forth with other dolphins.

They also communicate through nonverbal gestures like slapping their flippers in the water, leaping out of the water, or bumping each other.

7. Dolphins Can Live Up To 80 Years

Did you know that smaller dolphins can live up to 20 years while the larger dolphins (like the Orcas) can live up to 80 years? To the kids, that was insane!

8. Bottlenose Dolphins Have Between 72-104 Teeth

That’s a lot of teeth! It’s also good to know that they only have one set of teeth that last for a lifetime. The teeth last so long because they don’t use their teeth to chew food, just to catch it. Once they’ve caught their food (they eat fish, squid and crustaceans) they swallow it whole.

9. Dolphins Are Mammals Not Fish

Even though dolphins live in the ocean, they are still considered mammals and not fish. Why? Because they are warm blooded and fish are cold blooded. Unlike fish, they have to go to the surface to get air because they don’t breath through gills.

10. Dolphins Are Born with Hair

Well, not much hair. They are born with hair on the top of their rostrum (the jaw) but after a short time it falls out and doesn’t grow back.
