The Bottlenose dolphin has a single blowhole on the dorsal surface of the head. The blowhole can be closed by use of a muscular flap. A dolphin is able to exchange 80% or more of its lung air with each breathe, and typically rises to the surface to breathe through its blowhole two times a minute. However, they can, if necessary, remain underwater for up to 20 minutes. Dolphins sleep for approximately 8 hours in every 24, in periods of from several minutes to several hours. During the sleeping cycle dolphins remain near the surface swimming slowly, occasionally closing one eye, and one brain hemisphere remains active while the other hemisphere shuts down.
