12 amazing facts about the humpback whale
The humpback whale (Megaptera novaeangliae) is one of the ocean's most charismatic giants: an acrobatic, deep-voiced filter feeder that travels thousands of kilometres between cold feeding seas and warm breeding bays. Here are twelve facts that capture why it fascinates scientists and whale-watchers alike. For the full profile, see our humpback whale species guide.
1. Its scientific name means 'big wing'
The genus name Megaptera translates as 'big wing', a nod to the humpback's enormous pectoral fins.
2. Those flippers are the longest of any whale
A humpback's pectoral fins can reach up to roughly a third of its body length, longer in proportion than any other whale.
3. Only the males sing
Male humpbacks produce long, structured songs, mainly on the breeding grounds, that can repeat for hours at a time.
4. Their songs spread like hit tunes
A song gradually changes through a season, and new versions can pass from one population to another across an entire ocean basin.
5. They are heavyweight acrobats
Adults weigh roughly 25 to 30 tonnes yet still hurl themselves clear of the water in spectacular breaches.
6. They hunt with nets made of bubbles
Groups sometimes blow curtains of bubbles to herd krill and small fish into tight balls before lunging through them, a behaviour called bubble-net feeding.
7. They can eat over a tonne of food a day
During the feeding season a single humpback can strain well over a tonne of prey through its baleen plates each day.
8. They migrate around 8,000 km one way
Many humpbacks make one of the longest migrations of any mammal, around 8,000 km between feeding and breeding grounds.
9. Each tail fluke is a fingerprint
The pattern on the underside of a humpback's tail is unique, letting researchers identify individuals over decades.
10. They can live 80 to 90 years
Like other large baleen whales, humpbacks are long-lived; age is often estimated from layers in their earwax plugs.
11. They came back from the brink
Commercial whaling cut some populations by more than 90 percent, but after the 1985 whaling moratorium the IUCN reassessed the species as Least Concern in 2018, with about 84,000 mature whales and an increasing trend.
12. Not every population is safe yet
The global picture is bright, but the IUCN still lists subpopulations such as the Arabian Sea humpbacks as Endangered. Entanglement in fishing gear and ship strikes remain real threats, which is why WARN helps fund partner marine teams along Brazil's Abrolhos breeding coast. If these facts moved you, you can support that work.
