Blue whales are streamlined creatures with pale blue-gray coloration. In addition to being the largest animal, they are also capable of producing the loudest sound. Blue whales moan, grunt, and hum at impressive volumes of up to 180 decibles. When diving from the surface, blue whales arc at near vertical angles, exposing their broad tail flukes. The power needed to propel themselves through the water comes from their back muscles, not from their flippers.
