2013 Polar Animals Series - Humpback Whale One Dollar ($1) Uncirculated Australian Decimal Coin

Humpback whales are known for their magical songs, which travel for great distances through the world's oceans. These sequences of moans, howls, cries, and other noises are quite complex and often continue for hours on end. Scientists are studying these sounds to decipher their meaning. It is most likely that humpbacks sing to communicate with others and to attract potential mates.
These whales are found near coastlines, feeding on tiny shrimp-like krill, plankton, and small fish. Humpbacks migrate annually from summer feeding grounds near the poles to warmer winter breeding waters closer to the Equator.
Mothers and their young swim close together, often touching one another with their flippers with what appear to be gestures of affection.
