Dolphins are some of the coolest animals of the sea! People love dolphins because they are generally friendly, cheerful, and incredibly intelligent. Dolphins are entertaining to watch, whether it be at sea or in a show! However, there are many things that people do not know about dolphins. For example, there are about forty different species of dolphin across the planet, including killer whales. That’s right! Killer whales are actually a type of dolphin, something that most people do not know. This list is full of interesting facts about dolphins!
Dolphins actually give each other names! Researchers discovered this by listening to and observing them. They “whistle” and this is their form of communication.

Dolphins are actually camouflaged by nature. They are dark on the top and light on their bellies, to help them blend in.

When predators are looking upwards, they won’t see the dolphin because its light belly blends in with the bright sky!
There is an organization called Anti-Dolphin that believes that dolphins are a threat to humanity and should be exterminated.
