Wired.com: "The study by biologists at Aarhus University in Denmark concentrated on the dolphin’s whistle, which was believed to be produced by the resonance of air in the dolphin’s nasal air cavities. This would have implications for how dolphins communicate at depth — increased air pressure would affect the size of the nasal air cavities and therefore the pitch of the sounds they can make. Instead, the team discovered that the dolphin’s whistle isn’t in fact a whistle at all; but a sound produced by tissue vibrations."
