Humpback whale
Megaptera novaeangliae
Humpbacks travel thousands of kilometres each year to breed and feed. If we are lucky, we may hear a blow or glimpse a breach.
Least Concern (IUCN, 2018) means it is not at high risk of extinction worldwide today. The Arabian Sea and Oceania populations are Endangered.

Calm, give space
How it lives
Humpbacks filter krill and small fish from the water with several feeding methods. In some populations they trap prey inside rings of bubbles, known as bubble-net feeding. On the breeding grounds, males sing long, complex songs that change over time. Mothers and calves call to each other quietly, and calves spend about 21% of their time suckling.
Where it goes
Many humpbacks make one of the longest migrations of any mammal, travelling up to about 8,000 km (5,000 miles) between cold feeding waters and warm breeding waters. Routes and distances differ between populations, and Arabian Sea humpbacks do not make this classic polar migration.
Populations
Humpbacks are Least Concern worldwide, but populations differ a lot: the Arabian Sea and Oceania subpopulations are Endangered, and some other populations are still at risk. Bubble-net feeding usually happens on high-latitude feeding grounds, such as Norway and Alaska, not at breeding grounds like Moʻorea or Tonga. In the South Pacific, songs spread from one population to the next like a cultural wave, from Tonga to the Cook Islands to Moʻorea.
Meet it respectfully
We keep local legal distances and never chase or block a whale, separate a mother and calf, or place swimmers in front of travelling or feeding whales. Breeding and calving grounds need extra care, and a whale that chooses to come close is still our responsibility. Rules differ a lot by place: in Queensland and Commonwealth waters in Australia, boats must stay at least 100 m away (300 m from a calf) and swimmers must not approach within 100 m, and around Hawaiʻi US law keeps people at least 100 yards (91 m) away with no swimming. A startled whale's tail can endanger small boats.
Fun fact
Tap the bulb to light it up.
Bubble nets give about 7 times more prey per lunge, without a matching rise in energy cost.
Among seven baleen whale species studied, only humpbacks turn sharply enough to make a bubble net alone.
Mothers and calves 'whisper' to each other, with calls often heard only within 100 m.
Songs travel across the South Pacific like a cultural wave, from Tonga to the Cook Islands to Moʻorea.
