Humpback whale: Acrobatic animal

The humpback whale (Megaptera novaeangliae) is a species of baleen whale.

One of the larger rorqual species, adults range in length from 12-16 metres (39-52 ft) and weigh approximately 36,000 kilograms (79,000 lb). The humpback has a distinctive body shape, with unusually long pectoral fins and a knobbly head.

Found in oceans and seas around the world, humpback whales typically migrate up to 25,000 kilometres (16,000 mi) each year. Humpbacks feed only in summer, in polar waters, and migrate to tropical or sub-tropicalwaters to breed and give birth in the winter.

Like other large whales, the humpback was and is a target for the whaling industry. Due to over-hunting, its population fell by an estimated 90% before a whaling moratorium was introduced in 1966.

Stocks have since partially recovered; however, entanglement in fishing gear, collisions with ships, and noise pollution also remain concerns

There are at least 80,000 humpback whales worldwide. Once hunted to the brink of extinction, humpbacks are now sought by whale-watchers, particularly off parts of Australia, New Zealand, South America, Canada, and the United States.
