    • Where does the dolphin live?
      • Dolphins live in the sea.
    • Dolphins Habitat
      • Dolphins live in harbors, bays, lagoons, gulfs and tributaries. They do migrate if the water gets cold enough. Also they may migrate if the fish supply and feeding habits change. Some like cold and deeper water than others.
    • Who are the dolphin’s enemies?
      • Even though dolphins are very friendly animals, they have many enemies. Some of these enemies are tiger sharks, dusky sharks, bull sharks, and sometimes even orcas. When a dolphin can see that an animal is trying to prey upon it, the dolphin floats calmly, pretending it’s dead. This makes the shark think that some other animal already killed it. The dolphin will be ignored because sharks only like to eat fresh meat.
    • How does the dolphin look like? One other fact that you find interesting is how long these creatures are. The bottlenose dolphin, specifically, is 3 m (10 ft.) This dolphin can weigh up to 400 pounds. Now that’s a big animal!
    • How the dolphin communicates
      • When you hear the squeak of a dolphin, you automatically think that it’s saying something. Well, that’s true! But they don’t use their vocal cords to do that. The dolphin simply uses its blowhole. This works because the dolphin opens and closes the tiny hole. When the dolphin does this really fast, it creates the squeaky noise. The dolphin uses the air above the water to do this. Dolphins use the stored air in their blow hole to communicate under water.
