Humpbacks can be found in oceans worldwide. Once a heavily hunted animal, their numbers have rebounded under international protection and are now listed as Least Concern, though some regional populations remain vulnerable to threats such as entanglement, noise pollution, and climate change.
They are easily recognized by their exceptionally long pectoral fins, knobby head (tubercles), with spectacular behaviours such as breaching, flipper slapping and for their complex, region-specific songs.

Diet and Behaviour
Humpback whales are highly active and social animals, often seen breaching, slapping their long pectoral fins, and lob-tailing at the surface. They are curious and frequently approach boats, making them one of the most studied whale species. Known for their distinctive behavior when diving, humpbacks arch their backs high and lift their flukes vertically before descending. They also produce complex, region-specific songs during courtship, which are unique among rorquals and consist of multiple themes.
Humpbacks are filter feeders that consume krill and small schooling fish, using their baleen plates to strain food from the water. Their accessibility near coastal areas and striking surface activity make them one of the most recognizable and researched whales.
Breeding Cycle
During the breeding season, humpback whales migrate from their cold, nutrient-rich feeding grounds in polar regions to warm tropical or subtropical waters. These breeding areas are typically calm, shallow coastal zones that provide safety for newborn calves. Common breeding destinations include: Hawaii, Australia and the Caribbean.
These migrations can span thousands of kilometers, making humpbacks one of the longest-distance migrators among mammals.
Females give birth to a single calf every 2–3 years following a gestation period of about 11 months. Calves are usually born measuring around 4–5 meters in length and weighing approximately 1 ton, and they nurse for up to a year before becoming independent.
Humpback Whales FAQs
Where do humpback whales live?
Humpback whales live in oceans worldwide, primarily in polar, temperate, and tropical waters, depending on the season. They have two main habitat zones:
- Feeding Grounds: Cold, nutrient-rich waters in polar and subpolar regions during summer, such as the Arctic and Antarctica.
- Breeding Grounds: Warm, shallow tropical or subtropical waters during winter, including areas like Hawaii, the Caribbean, Australia.
What to humpback whales eat?
Humpback whales gulp huge mouthfuls of water and prey, then push the water out through their baleen plates, trapping the food to swallow. They use clever methods like bubble-net feeding, where they circle fish with bubbles to form a dense, easy-to-catch ball.
During the Summer season (cold waters), humpbacks feed on krill, herring, mackerel etc to build fat. transitioning into warm waters (Winter), they then rely on their fat to survive while breeding in tropical areas.
How can you identify a humpback whale?
They have a generally dark body with variable white markings on the underside and flippers, and a small, rounded dorsal fin positioned far back on the body. When diving, they arch their back prominently and often lift their flukes vertically, which display unique black-and-white patterns used for individual identification. Their blow is tall and bushy, and they are known for dramatic surface behaviors such as breaching, flipper slapping, and lob-tailing, making them one of the most recognizable whale species.
