Killer whale (Orcinus orca) breaching (lower left). The killer whale is actually a member of the dolphin family. Breaching is when a whale or dolphin leaps from the water. Reasons for this behaviour are thought to include communication, stunning its fish prey, courtship behaviour, or to clean its skin of parasites. A tourist boat (at right) is observing the whale. Photographed near Sitka, Alaska, USA.
