Dolphins make a sound that travels quickly through water. this sound is bounced back and the information tells the dolphin how close and how big a fish is. It's believed that the whistling sounds dolphins are known to make also are part of echolocation. They are able to pass air through the blowhole. If you take a balloon, partially blow it up, and then slowly let air out, that is similar to the same results they get.
