The humpback whale is a species of baleen whale with a distinctive body shape. It is known for breaching and other distinctive surface behaviors, making it popular with whale watchers. Males produce a complex song lasting 10 to 20 minutes, which they repeat for hours at a time. Its purpose is not clear, though it may have a role in mating. Found in oceans and seas around the world, humpback whales typically migrate up to 25,000 km (16,000 mi) each year. Humpbacks feed in polar waters, and migrate to tropical or subtropical waters to breed and give birth when they fast and live off their fat reserves. Their diet consists mostly of krill and small fish. Like other large whales, the humpback was a target for the whaling industry. Once hunted to the brink of extinction, its population fell by an estimated 90% before a 1966 moratorium. While stocks have partially recovered, entanglement in fishing gear, collisions with ships and noise pollution continue to impact the population of 80,000. Photographer: NOAA Photographer |
