When people think of dolphins, the bottlenose dolphin is usually the dolphin that comes to mind. These dolphins are known for their appearances in aquarium shows, such as SeaWorld, and for their friendly nature in the wild. They will often swim up to humans and interact with them without threatening them. In fact, bottlenose dolphins have been known to protect humans from sharks.
Bottlenose dolphins can jump as high as 16 feet in the air and can communicate underwater with their fellow dolphins through echolocation. Echolocation is the use of clicking sounds that can be heard underwater. The sound is made by one dolphin and is sent out to the others. These dolphins then interpret the sound to determine the dolphin that sent it and the location of that dolphin.
