Behavior of humpback whales.

Humpback whales are known for their fascinating and complex behaviors, which have captivated researchers and observers for years. These magnificent marine mammals exhibit a wide range of behaviors that encompass feeding, social interactions, migration, and breeding.

Feeding Behavior:

Humpback whales are filter feeders, and their feeding behavior is often characterized by a technique known as “lunge feeding.” This involves lunging forward with their mouths wide open, engulfing large volumes of water along with their prey, such as krill or small fish. Afterward, they use baleen plates in their mouths to filter out the water, while retaining the food. This feeding behavior is often observed in areas where there is an abundance of prey.

Social Interactions:

Humpback whales are highly social creatures and exhibit various social behaviors. They are frequently seen in groups, ranging from small pods to larger aggregations. These groups can consist of individuals of different ages and sexes. Some common social behaviors include breaching (propelling their bodies out of the water and crashing back down), tail slapping, flipper slapping, and spyhopping (raising their heads vertically above the water to observe their surroundings).


Humpback whales are known for their impressive long-distance migrations. They undertake seasonal journeys between feeding grounds in polar regions and breeding grounds in warmer waters. These migrations can cover thousands of kilometers and often follow well-established routes. The exact mechanisms and cues that guide their migrations are still the subject of scientific investigation.

Breeding and Reproduction:

Breeding behavior among humpback whales is a remarkable spectacle. Male humpbacks produce complex songs that can last up to 20 minutes and are repeated over long periods. These songs are believed to play a crucial role in attracting and communicating with females. Breeding also involves competitive behaviors among males, such as aggressive displays and physical interactions.

Parental Care:

Humpback whales display strong maternal care. After a gestation period of approximately 11 months, females give birth to a single calf. The calf relies on its mother’s milk for nourishment and protection. The mother provides guidance, protection, and teaches the calf essential skills such as feeding techniques and migration routes. The bond between mother and calf is strong and can last for several months before the calf becomes independent.

Acrobatics of humpback whales.

Humpback whales are renowned for their spectacular acrobatic displays, which leave observers in awe of their agility and power. These acrobatic behaviors are a testament to the remarkable capabilities of these massive marine mammals.


One of the most iconic acrobatic behaviors of humpback whales is breaching. Breaching involves the whale propelling its entire body out of the water and crashing back down with a tremendous splash. This powerful maneuver can be repeated multiple times in succession. The reasons behind breaching are not entirely understood, but it is believed to serve multiple purposes. It may be a form of communication, a way to dislodge parasites from their skin, a means of attracting a mate, or simply an expression of their strength and vitality.

Tail Slapping:

Another striking acrobatic behavior displayed by humpback whales is tail slapping, also known as lobtailing. This behavior involves the whale forcefully slapping its large tail flukes against the water’s surface, creating a loud splash. Tail slapping can be performed in various patterns and frequencies. While the exact function of this behavior is not fully known, it is thought to serve as a form of communication between individuals or a warning signal to nearby whales.

Pectoral Fin Displays:

Humpback whales also showcase their acrobatic abilities through pectoral fin displays. These displays involve the whale lifting one or both of its massive pectoral fins out of the water and waving or slapping them against the surface. This behavior is often observed during social interactions, such as mating or territorial disputes. The purpose of pectoral fin displays is believed to be a means of communication, asserting dominance, or attracting potential mates.


Spyhopping is a behavior where humpback whales raise their heads vertically out of the water, allowing them to observe their surroundings. It is a unique acrobatic behavior that enables the whales to get a better view above the waterline. While the exact reasons for spyhopping are not fully understood, it is thought to serve a variety of purposes, including navigation, prey detection, social interactions, or simply curiosity about their environment.

Scientific hypotheses.

Scientific hypotheses refer to proposed explanations or predictions based on existing evidence and knowledge, which are subject to testing and further investigation. In the context of humpback whales and their acrobatic behaviors, scientists have put forth several hypotheses to try to understand the reasons behind these captivating displays.

Mating and Courtship:

One hypothesis suggests that acrobatic behaviors in humpback whales, such as breaching and tail slapping, play a role in courtship and mating rituals. These displays could serve as a way for males to attract females, demonstrate their strength and fitness, or establish dominance among competing males. The impressive nature of acrobatics might act as a visual spectacle, influencing mate choice and enhancing reproductive success.


Another hypothesis proposes that acrobatic behaviors serve as a form of communication between humpback whales. Breaching, tail slapping, and pectoral fin displays could convey information about territory, social status, or group cohesion. These displays might also serve to coordinate group movements during feeding or migration, enabling efficient communication over long distances.

Parasite Removal and Body Maintenance:

Acrobatic behaviors could also be related to parasite removal and general body maintenance in humpback whales. When breaching or tail slapping, the forceful impact with the water may dislodge parasites, barnacles, or other unwanted organisms from the whale’s skin. By engaging in acrobatic displays, humpback whales may effectively cleanse their bodies and maintain optimal health and hygiene.

Playful Behavior:

Some scientists suggest that acrobatics in humpback whales could be a form of play or recreational behavior. Similar to how humans engage in sports or playful activities, humpback whales may perform acrobatics simply for the enjoyment of it. Play behaviors may help in building social bonds, refining physical skills, or reducing stress levels, contributing to the overall well-being of the individuals.

Courtship and reproduction.

Courtship and reproduction play a significant role in the lives of humpback whales. These behaviors are crucial for ensuring the continuation of the species and are marked by fascinating rituals and interactions.

Breeding Grounds:

Humpback whales have specific breeding grounds where they congregate during the mating season. These breeding grounds are often located in warmer waters closer to the equator, providing an ideal environment for courtship and calving.

Male Songs:

One of the most remarkable aspects of humpback whale courtship is the elaborate songs produced by the male whales. These songs are complex and can last up to 20 minutes or more, consisting of a series of repeated patterns and themes. The purpose of these songs is believed to be attracting female whales and establishing dominance among competing males. The songs can carry over long distances and are specific to each population or subgroup of humpback whales.

Competitive Displays:

Male humpback whales engage in competitive displays to gain the attention of females and establish their dominance. These displays can include breaching, tail slapping, and aggressive behaviors towards other males. By showcasing their physical strength and agility through acrobatic displays, males aim to impress females and increase their chances of successful mating.
