2. These marine giants possess a subpar sense of smell, as their brains lack the essential olfactory bulbs required for this function.


3. In Hawaiian waters, stringent federal regulations forbid any form of disturbance or closeness to these majestic creatures within a 100-yard radius. Additionally, boaters are cautioned to decelerate upon spotting a whale and to refrain from lingering near a mother-calf pair for more than half an hour, ensuring the safety and well-being of these cetaceans.

Humpback Whale Facts Keep Your Distance

4. Humpback whales share a distant relation with the hippopotamus; both species diverged from a mutual ancestor approximately 60 million years ago.


5. Humpback whales are not monogamous creatures and do not form lifelong mating bonds. During a single breeding season, female humpback whales are known to mate with multiple male partners.

6. In order to secure their chances of mating, male humpback whales adopt a strategy known as “primary escorting,” whereby a single male stays in close proximity to his female interest and discourages advances from other potential suitors. Rival males, known as “challengers,” however, continuously attempt to usurp the primary escort’s position and gain access to the female for mating purposes.


7. The unique vocalizations or songs of humpback whales, specific to individual populations, undergo a fascinating metamorphosis over an extended period. Their musical compositions demonstrate a continuous evolution— both in terms of their sequences and structural elements—resulting in the eventual birth of an entirely new and distinct song that is sometimes passed amongst different populations. The high level of intricacy and variation in these vocalizations is indicative of the whales’ complex social structure and communication abilities.


8. A significant percentage, close to 75 percent, of humpbacks that migrate to Hawaii during the winter months, can be primarily located in the waters of Maui County.

9. Upon breathing, the humpback whale’s blowhole expels air at a remarkable speed that nearly reaches 300 miles per hour.

10. The process of a humpback whale calf consuming milk differs from the conventional way of suckling due to the absence of the required muscle structure in their tongues. Instead, pressure is applied by the calf’s mouth against the exposed nipple through the mammary slit, prompting the mother to forcibly project milk directly into her offspring’s mouth, ensuring efficient nourishment.


11. Humpback whales, known for their incredible size, typically reach lengths of 40 to 50 feet. Interestingly, female humpbacks tend to be larger than their male counterparts, with an average length that surpasses males by 3 to 5 feet.


12. The gestation period of a female humpback whale is quite lengthy, ranging from 11 to 13 months before she gives birth to her offspring.

13. Throughout the summer months, adult humpback whales actively feed, leading to a significant accumulation of blubber. This layer of fat can measure between five to seven inches thick at the peak of the feeding season. However, after the breeding season comes to a close, their blubber layer typically dwindles down to less than two inches in thickness.


14. One unique feature of humpback whales is their sizable 14-inch wax earplug that effectively safeguards their hearing apparatus. This specialized plug serves to keep water from being forced into delicate areas like the ear canal and middle ear, effectively preventing damage.

15. When comparing the composition of a humpback whale’s body to that of a human, there lies a notable difference in the proportion of bone mass. While human bones make up approximately 50 percent of an individual’s total body weight, a humpback’s skeletal structure accounts for a mere 15 percent of its overall weight, highlighting the significant difference in body composition between these two species.


16. Humpback whales, also referred to as rorquals which is a Norwegian term meaning “red whales,” derive this unique nickname due to their distinct appearance. The exquisite deep red hue of their blood imparts a beautiful pinkish luminescence to the white portions of their throat and belly, creating a striking contrast.


17. The brain of a humpback whale is an astonishingly large organ, weighing in at an impressive 14 pounds – close to five times the size of a human brain. Yet when it comes to the largest known brain in the animal kingdom, the humpback is eclipsed by the sperm whale, whose brain tips the scales at a staggering 20 pounds.

18. The humpback whale, known for its majestic presence in the ocean, is distinguished by having the most extended pectoral fins among all species of whales and dolphins. These fins can grow up to an impressive 15 feet in length, accounting for nearly one-third of the creature’s total body length.


19. In terms of reproduction, female humpback whales typically follow a two-year cycle in which they give birth and take a year of rest before having another offspring. However interestingly enough, researchers have observed a small percentage of females veering from this pattern, giving birth to a newborn calf in back-to-back years.

Humpback Whale Facts Learning

20. One of the unique anatomical features of humpback whales is the presence of 15 to 25 longitudinal grooves, referred to as ventral pleats, along their throat region. These specialized folds allow them to expand their mouth capacity considerably when feeding, providing a more efficient means of capturing their prey.

21. The enchanting and complex songs of male humpback whales have captivated researchers and marine enthusiasts worldwide. While performing these vocal displays, the whale holds its breath and remains submerged underwater for varying durations, ranging between eight minutes to an astonishing one hour in some cases. It’s postulated that the length of these downtimes may be an indicator of the individual humpback’s fitness and overall health.


22. During their migratory journey, humpback whales typically move at speeds ranging from three to five miles per hour. The journey, which takes them from their feeding grounds to their breeding areas, lasts anywhere between 30 and 60 days.

Humpback Whale Facts Long Journey

23. Scientifically known as Megaptera novaeangliae, which translates to “big-winged New Englander,” the humpback whale was named after its distinctive long pectoral fins observed when the species was first described in the Northeast Atlantic. The common name “humpback” is derived from the whale’s unique behavior of significantly arching its back above the water’s surface before initiating a dive.


24. The milk produced by mother humpback whales boasts an incredibly high-fat content, reaching up to 40 percent, which is considerably more than the 4 percent fat found in human milk. This rich composition is essential for the rapid growth and development of their calves.


25. Humpback whales are renowned for their enchanting songs, which are intricate, organized sequences of various sounds combined into a series of phrases. These songs can be as long as 20 minutes and can be repeated continuously for several hours. These melodious vocalizations are thought to play a crucial role in either mating rituals or social interactions among these gentle giants.
