Many species of whales live in social groups that communicate by sound. These magnificent marine mammals can dive to great depths and stay under for long periods of time. When these giant creatures do surface, the spurt of water that rises out of their blowhole is a release of air. They will then engage in typical behaviors like raising their flukes before a dive, slapping the water with their fin, or spy hopping to get a view above the water's surface. This calendar features exquisite photos of various whale species as they swim and frolic.
