HUMPBACK WHALE FACTS
The Humpback Whale has a dark grey or black body, with white markings on its underside. The black and white markings are unique and can be used to identify individual animals. They have long pectoral fins with bumps on the leading edges. It has narrow head covered in protuberances (bumps), and often has barnacles attached to head and fins. It has a very small dorsal fin far down its back.
Adults are 14m to 18m. The calves are 4m to 5m at birth
Humpback whales feed in the Antarctic waters from November to May. They migrate north to their breeding grounds off the Queensland coast in May/June.
Humpback do not have teeth. They feed by filtering krill (kind of shrimp) between baleen plates attached to the top jaw. They have 300-400 of these baleen plates. They also eat small schooling fish caught by opening their mouths and lunging into the school of fish.
Gestation period is about 11 months. Females have a calf every 2-3 years, and the calf is weaned after 11 months. The young reach maturity at about 12-15 years and can start breeding after about 7 years. The breeding season is between June to October.
