They have a thick layer of blubber around 5 inches thick, which helps insulate them from the cold. Their forehead is prominently rounded, aiding in their identification. They also have a very flexible neck, allowing them to move their head in all directions. They also have another feature is that they do not have a dorsal fin, which helps them move easily under the ice, preventing them from getting injured by colliding with the ice.
If we talk about the knees of beluga whales, a question arises as to how they can have knees since beluga whales don’t have legs. Yes, it is true that they don’t have legs, so they don’t have knees in their physical anatomy. However, inside their body, there are some internal structures that might represent the remnants of knees due to their evolutionary ancestors. These joints are located within their hip region, and their function is limited, such as helping with the movement of their tail and swimming.
Their knees are not as flexible as those of humans. We can also say that the physical structure of beluga whales evolved from land mammals to marine mammals, in which they once had legs and knees, but now only residual bones and joints remain hidden.
Reproductive and Social Behavior
Sexual behavior of beluga whale:
- Their sexual behavior is such that males mature at around 8 to 10 years of age, while females mature between 4 to 7 years of age.
- The pregnancy period for females lasts 14 to 15 months, and typically, each female gives birth to only one calf every three years.
- The average age for female beluga whales to give birth is 8.5 years.
- Each beluga whale has a lifespan of 30 to 50 years if predators do not hunt them.
- When talking about the breeding of beluga whales, females give birth to a calf once every 3 years, and it is very rare for twins to be born.
- The mother feeds her calf milk for 2 years.
- The calf prefers to stay with its mother because she can protect it better from predators, and she teaches her calf to swim very quickly.

Social behavior of beluga whale:
If we talk about the social behavior of beluga whales, it is very complex. They always live in pods, and the size of their pods consists of 5 to 10 belugas. Beluga whales communicate with each other through diverse vocalizations, such as clicks, clangs, and body language. They use head nods and tail snaps to express their feelings, including warnings. Additionally, beluga whales have such strong bonds that they hunt in pods and also migrate in pods. When the cold intensifies in the Arctic, they migrate toward warmer areas, and during migration, their pod size can grow to thousands.
Migrations:
They migrate every year for their survival; without migration, they would not be able to survive. They migrate four times a year, during spring, summer, autumn, and winter, each time for their specific survival needs. Such migrations also offer them some good part of learning and experience.
Feeding Habits and Predation Risks
Diet and Hunting strategies:
While addressing the eating habits and the dietary patterns of the beluga whales, it is essential to mention that their nutrition is largely reliant on seasonal changes as they move 3 to 4 times within the year. Fish is their staple food. Other than fish, they are fond of having shrimps, crabs, squids and some other types as well.
The beluga whales are also very known for their hunting strategies. They use their super listening ability to determine where and in which direction the prey is located. Their flexibility in the neck and mouth, along with echolocation, assists them in the hunting process. Besides, they hunt in groups, surrounding and effectively capturing the prey. Such approaches indicate that beluga whales use specific hunting methods for successful hunt hunting.
Threats:
A number of predators prey on beluga whales with the most common being the killer whale and polar bear. In addition to this, they are also at great risk from humans, such as human bycatch and hunting, which cause many whales to die. Apart from this, noise pollution and climate change also have a significant impact on the beluga whale population.
Conservation Efforts and Cultural Significance of Beluga Whale
Protection Efforts:
When talking about the protection of beluga whales, many organizations are being established, both internationally and locally, to protect mammals, including beluga whales. These efforts address issues such as bycatch and hunting, and there is also a lot of work being done on climate change to ensure no harm comes to any beluga whale and to keep their population sustainable.
Role in Ecosystems:
Beluga whales are important to the home of oceanic life. They assist uphold the balance of the oceanic ecosystems due to their hunting and feeding characteristics. Beluga whale hunting habits also help to regulate the balance within the food webs of the ecosystems. Through predation, some predator species promote the abundance of almost all prey species. Then, it helps curb competition from other species. You are as good as you are good. As per the researchers, the Shqurunnis resources above are of great value to the ocean, as well as to the equilibrium of the ecosystem, which is essential for their sustainability in the ocean.
Unique Traits and Behavior:
Beluga whales are often considered very cute due to their smiling faces, small size, small eyes, and rounded bodies. They are famous for their lovable and playful behavior, which is why they are the most frequently sought-after whales by humans. Beluga whales are also famous for their unique features, such as their ability to mimic human speech patterns.
Additionally, they can imitate different sounds. Because of their playful behavior, they are considered very close to humans. They also play with objects like wood logs and ice chunks, and this behavior makes them even more fascinating.
Cultural Significance:
Arctic communities consider belugas very important, as they are mentioned in their culture and folklore. The hunting of belugas is mostly done to meet their needs, such as making clothes from their thick blubber, which provides significant protection against the cold. The hunting of belugas is an important part of their lifestyle and is also a crucial aspect of their economy and traditions.
The History of Beluga Whale:
Belugas are well-liked for their white colour and friendly and playfull behavior, playing an important role in the Arctic ecosystem and also in culture and History. For many indigenous cultures, they represent the connection between the sea and humans, often said to bring messages from the sea. The beluga whale becomes a symbol of life and continuous in these communities.
Historically, European explorers were attracted to the playful behaviour and vocalizations of belugas. They became important to Arctic communities, providing a source of survival, and their hunting created a feeling of respect and gratitude. In mythology and folklore, particularly in Arctic and sub-Arctic cultures, belugas are spiritual beings that help guide souls after death.
Beluga whales have also left a mark in art and literature. Its striking appearance inspires artists to create works of beauty, while in literature, the creature symbolizes the mystery of nature. Modern media has placed belugas in popular culture, making them creatures people of all ages love in zoos and aquariums as they play and bring laughter.
Belugas have also emerged as a symbol of change in the environmental realm. Climate change has started having impacts on the Arctic system, and the whales have created a sense of movement regarding protecting their habitat and assuring species’ survival. Ecotourism and global consciousness on this matter are now the greatest necessities to protect belugas and their habitat.
The Mystery of the Beluga Spy Whale:
In 2019, a beluga whale discovered in Norway’s Arctic region attached with a harness and equipment, increasing the vigilance of it being a Russian spy. The harness bothers the caption “Equipment of St. Petersburg,” suggesting a connection to Russia. This unusual whale, which had been found in an area far from its usual habitat, was thought to have been sent by Russia for a covert mission. The harness was advanced, mounted with a camera, and possibly with sensors, which further strengthened the idea that the whale was used for surveillance purposes. Russia has also made history by using animals to carry out military operations during the Cold War, including trained dolphins and dogs, which added further to these suspicions. Its fast adaptation to being released in the wild suggested it was not a mere research subject but rather perhaps a tool for some sort of secret strategic operation. Still, debates abound, but the mysterious appearance and equipment of the whale keep alive the theory that it belonged to some kind of Russian spy mission.
The Airbus Beluga:
The Beluga Whale plane, also known as the Airbus Beluga, is a cargo aircraft developed by Airbus for transporting oversized and heavy material things. Named after the marine mammal, its unique design resembles the belugas rounded and streamlined body. Introduced in 1995, the plane was initially used for transporting Airbus components to assembly plants and now serves various heavy cargo transport purposes, with a payload capacity of up to 47 tonnes.

A330-600ST
The Beluga plane project, known as the A300-600ST, was launched in 1994, replacing the Super Guppy. Its bulbous design and spacious cargo bay allow it to transport large components like wings, engines, and fuselages. Following its success, the BelugaXL, introduced in 2019, provides even greater capacity.
The aircraft supports critical missions such as Airbus A380 production, humanitarian aid, and space program logistics. It efficiently delivers large items across Europe and supports global logistical operations. Key features include advanced aerodynamics, two-pilot operation, and a cargo volume of 1,400m³.
Compared to the other cargo planes, the Beluga excels in specialized transport, with its range and cargo being smaller than some models. Regardless, its efficiency and purpose-driven design make it crucial for Airbus Beluga.
BelugaXL and Airbus enter space for sustainable energy, and humanitarian missions, ensuring the plane’s bright future in global cargo and innovation.
The Role of Beluga Whale in Finding Dory:
Pixar’s film Finding Dory is completely based on the thought of friendship, family, and self-discovery. The film involves many sea creatures, but the beluga is a very main character in it. Belugas are known for their funny behaviour and echolocation abilities. In this film, this whale is not only shown as funny but is also portrayed in great detail to highlight how friendly and emotional it is and how it helps others in difficult times. Through its character, we learn many lessons.
If we talk about the film, the main character is Dory, who suffers from short-term memory loss, which makes her forget small things. In the movie, Dory and her friends Nemo and Marlin are lost and are trying to find their family. Dory is also trying to find her memories. While searching for her family, they meet a beluga who helps them find Dory’s family. This whale uses its echolocation power to find paths and help Dory reach her family.
All of them help each other like a family during difficult times, and in the end, after all the efforts, hardships, and struggles, Dory finds her family and also recovers her memories. This whale plays a very significant role in this.
This film teaches us that we should interact with people because if we are in trouble, that person might help us. It also teaches us that if we are in trouble, we should work as a team, help each other in difficult times, and support each other emotionally as well.
