Main Characteristics
Humpback whales are marine mammals that belong to the baleen whale family. They can grow to about 60 feet (18 meters) in length and weigh up to 30 tons. Despite their impressive size, they are considered smaller whales. Their most distinctive features include numerous wart-like tubercles on their heads, long flippers (pectoral fins), and broad throat grooves. Most have white spots on their skin, which are scars from barnacle infestations.
Name
The humpback whale gets its name from the way it arches its body before diving, creating the appearance of a hump. Additionally, there is a small hump located near its dorsal fin. Its scientific name, "Megaptera" (novaeangliae), translates to "big wings", highlighting its notably long pectoral fins.
Distribution and Habitat
Humpback whales inhabit all oceans. During the summer, they are found in the cold polar seas, where there is an abundance of fish. In the winter, they migrate to tropical and subtropical waters. They travel vast distances, covering up to 15,500 miles (26,000 km).
Stranded Animals
In recent years, the number of stranded humpback whales has been increasing. They often strand due to illness, such as parasitic infections. In 2019, a dead calf was discovered in the Amazon. In 2022, two whales perished along the Dutch coast—in Zeeland and Cadzand. In Germany, a deceased whale was found in St. Peter Ording in 2025.
Humpback Whale Watching
The best places to observe humpback whales include Australia, Mozambique, French Polynesia, the Caribbean, Mexico, the Azores, Iceland, Costa Rica, Norway, and Tonga. These whales are often spotted in the waters around New York due to the abundance of fish – even in the Hudson River!
Way of Life
Humpback whales typically live as solitary creatures. However, in areas rich in fish, they may gather in larger groups to hunt together.
Anatomy and Appearance
Size and Weight
Humpback whales can grow up to 60 feet (18 meters) long and weigh between 25 to 30 tons. That’s nearly the size and weight of two city buses.
Pectoral Fins
Among all whales, humpback whales have the longest pectoral fins, also known as flippers. These can reach lengths of up to 16 feet (5 meters). They were originally arms that have evolved into fins over time. Therefore, it can be said that humpback whales have the longest arms in the animal kingdom. Still, these fins only account for about one-third of their total length.
Tail Fin
Compared to its body size, the humpback whale has the largest tail fin of all whales. One individual captured in 1904 had a tail fluke that measured 17.3 feet (5.28 meters) wide, which is about as wide as a giraffe is tall.
Baleen
Humpback whales do not have teeth in their mouths. Instead, they have horn-like plates known as baleen. These structures allow them to filter fish from the ocean.
“Warts”
The head of the humpback whale is covered in “warts”. These are known as tubercles, which are bumpy skin thickenings from which fine hairs grow. They assist the whale in better perceiving its surroundings.
Humpback Whale or Blue Whale – What’s the Difference?
Humpback whales and blue whales are both large marine mammals. Distinguishing between them is quite simple once you know what to look for: it’s all about the pectoral fins! Blue whales have much shorter flippers. This alone is enough to tell the two apart.
Adaptation to Habitat
The humpback whale is perfectly suited to its environment:
- Streamlined body – allows for effortless swimming
- Blubber (fat layer) – keeps warm in cold waters
- Long flippers – aids in swimming and steering
- Large tail fin – acts as a “motor” for migrations and dives
- Long migrations – utilizes various habitats
- Blow nets – increases hunting success
Diet
Humpback whales are carnivorous. They primarily feed on small shrimp-like crustaceans known as krill. Additionally, they enjoy small fish as part of their diet. Since their prey mainly resides near the coast, these whales are often found in those areas. They consume between 1,984 to 3,086 pounds (900-1,400 kg) (!).
Behavior
Why Do Humpback Whales Breach?
Humpback whales love to leap out of the water and twist in the air before breaching with a huge splash. They do this to shake off parasites on their skin, communicate with fellow whales, or impress potential mates. They also enjoy swimming on their backs while stretching their fins up into the air.
Why Do Humpback Whales Stick Their Heads Out of the Water?
Humpback whales often raise their heads above the water while keeping the rest of their bodies submerged. They can stay like this for up to 30 seconds, looking around. They just like to know what's happening around them!
Migration
How Far Do Humpback Whales Migrate?
Among all mammals, humpback whales undertake the longest migrations. They swim up to 8,000 miles (13,000 km) each way, totaling 15,500 miles (26,000 km) in a year.
Why Do Humpback Whales Migrate?
They have a good reason for traveling such long distances: they find the most fish in their summer feeding grounds near the Arctic Circle. In their wintering grounds in warmer waters, they raise their young. For example, from May to September, they are in the icy seas off Alaska, and between November and May, they are in the tropical waters around Hawaii.
Singing
Humpback whales are famous for their "magical" songs that they sing underwater. Their songs last between 10 to 20 minutes and can repeat for hours on end. It seems these creatures suffer from earworms (just a little joke!). They sing so loudly that their songs can be heard from over 18 miles (30 km) away.
Hunting Technique
Humpback whales possess a hunting technique that is truly one-of-a-kind in the animal kingdom: When they encounter a large school of fish, they swim just below the surface and create rings of air bubbles with their blowholes. The fish become disoriented by the bubbles, losing their sense of direction and remaining trapped within the rings. This makes them easy prey for the humpbacks! They don’t just create one ring; they form several and arrange them in a spiral pattern. From above, it looks spectacular.
Are Humpback Whales Dangerous?
Humpback whales are only dangerous to krill and fish - not to humans. They are generally peaceful and friendly, targeting much smaller prey. In 2025, however, a humpback whale accidentally swallowed a kayaker off the coast of Chile. Why? Biologists believe it was an accidental gulp while surfacing. The whale spat him out a few seconds later - unharmed. It was likely a surprise for both! In fact, a humpback whale couldn't swallow a human because its throat is too narrow.
Senses and Abilities
Diving
Humpback whales can dive to depths of 500-650 feet (150-200 meters). At this depth, they typically spend around 15 minutes, and sometimes even up to 30 minutes.
Sleeping
For us humans, breathing is something we cannot consciously control. However, humpback whales can consciously manage their breathing, similar to some other marine animals, and they must intentionally surface to breathe. So, what happens when they want to sleep? A portion of a humpback whale's brain remains active, allowing them to stay semi-awake, perform simple swimming movements, breathe, and be aware of their surroundings.
Intelligence
Tool Use
Yes, it's true. Humpback whales use tools. They create rings of air bubbles with their blowholes, which act like a fishing net to trap their prey. In 2024, scientists discovered that they catch seven times more fish using these rings. This technique is unique, requires a high level of intelligence, and meets all the criteria necessary to be considered tool use.
Grammar
The songs of humpback whales are remarkable. They even exhibit a form of "grammar". The whale connect sounds in various ways to form "sentences". These, in turn, create a rich song composed of verses and melodies. Scientists believe that the singing serves to locate other humpback whales and to attract them.
Life Expectancy
Humpback whales can live to be 80-90 years old.
Enemies and Threats
Natural Enemies
The only natural predators of adult humpback whales are great white sharks. Young whales are often preyed upon by sharks, orcas, and small killer whales.
Human Impact
Humpback whales actually have little to fear - except for humans. They pose the greatest threat to these majestic creatures.
Hunting
Humpback whales are hunted for their meat, their oil for use in soap, cosmetics, or as fuel in lamps.
Fishing
Humpback whales often get entangled in the nets of large fishing trawlers and die from suffocation.
Ships
Humpback whales are frequently injured by ships, either by getting caught in their propellers or colliding with them.
Noise
The noise from ships is not only unpleasant for humpback whales. It confuses them and disrupts their communication with each other.
Climate Change
Humpback whales feed on krill and fish that inhabit cold seas. Due to climate change, the oceans are warming, leading to a decrease in krill and fish – and consequently, whales have less food available.
Pollution
Humpback whales are threatened not only by climate change. Pollution from oil, mercury, microplastics, and plasticizers makes them sick and destroys their habitat.
How Many Humpback Whales Are Left?
The global whaling ban of 1986 has prevented humpback whales from being driven to extinction through hunting. However, this does not mean that the species is thriving. Japan, Iceland, and Norway have chosen to ignore the ban and continue hunting for economic reasons. Today, there are only about 84,000 adult individuals left. Since the population is stable and sufficiently diverse, humpback whales are currently classified as "not endangered".
Reproduction
Mating
Humpback whales mate in warmer, tropical seas. The males perform spectacular jumps, slap their tails, and sing to attract the females.
Gestation and Birth
The gestation period lasts 11 months. This means the calves are born just as their mothers return to warmer waters. At birth, the "little ones" are already 13 feet (4 meters) long. They are nursed for a year and double their weight each year. The bond between mother and child is very strong.
Fun Facts
In "Star Trek IV: The Voyage Home", Captain Kirk travels back to the 1980s to bring a pair of the critically endangered humpback whales to the future in order to save them.
