The humpback whale is the ocean's great singer. Each year, it changes its song to find a new mate. Besides singing underwater, humpbacks often will announce their presence by leaping out of the water or slapping its surface with their scalloped tails. The food is then strained through fringed plates called baleen in the whale's mouth instead of teeth.
Scientists classify whales as either baleen or toothed.
