*Top 28* Amazing Beluga Whale Facts
Beluga Whales have been on earth for 9-10 million years. Their ancestors lived in warm waters. However, the entire Beluga population of 150,000-200,000 currently reside in the icy waters of the Arctic.
They have evolved with the changing Arctic ice conditions over millions of years and are now white colored so they can blend in with snow and ice.
One of the smallest whale species, Belugas are known for their prominent foreheads and melodic songs.
Read on to learn more Beluga Whale Facts!
1) Beluga Whales are White
All Beluga Whales are white colored. This helps them blend in with the icy Arctic waters where they reside. And it provides them with a degree of protection against predators such as polar bears and orcas.
Belugas are cetaceans, which are aquatic mammals that includes whales, dolphins, and porpoises. They are the only cetaceans that are white.
Fun fact! The Word beluga comes from the Russian word belyj which means white.
2) Beluga Whales live in the Arctic
Beluga Whales inhabit the Arctic and subarctic coastal waters of Canada, Russia, Greenland (Denmark), the United States (Alaska), and Norway (Svalbard).
In the summer and early autumn they migrate south to warmer sub-arctic waters to molt, feed, and give birth. This includes the Bering Sea, Hudson Bay (Canada), and the coast of Greenland. They prefer shallow coastal waters, estuaries and river basins.
Most animals migrate south for the winter. As strange as it sounds, in the winter Belugas return to the Arctic ice pack to feed.
3) Beluga Whales are Marine Mammals
Beluga Whales are mammals. They belong to a group of marine mammals known as cetaceans, which includes whales and dolphins.
Mammals are warm blooded, have lungs that breathe air, and a complex brain. And they give birth to live young and nurse them.
4) Belugas are Toothed Whales
Whales fall into two main types – Toothed and Baleen. Toothed whales have teeth that they use to catch prey. There are 76 species.
In contrast, Baleen Whales have plates in their mouth that strain prey from the water. There are 15 species.
Beluga Whales are toothed. They have 30-40 conical teeth. However, they rarely chew their food. Instead, they swallow their prey whole. They rely on their teeth for grasping rather than grinding. Larger prey may be torn into smaller pieces
5) Belugas are one of the Smallest Whale Species
There are 91 Whale species. Belugas are one of the smallest. Males grow to 13-20 feet long and weigh between 2,000-3,000 pounds. Females are smaller than males, rarely growing over 12 feet.
Incredibly, babies are 5 feet long and 90-130 pounds at birth! They do not reach full size until age 10.
6) Belugas have Prominent Foreheads
Beluga Whales have are easily recognized by their prominent foreheads. It houses their melon, which is a specialized fatty organ which is used for echolocation.
7) Beluga Whales have a Melon for Echolocation
All toothed whales – including Belugas – have an organ on their foreheads called a melon. It is different from the brain, which is the body’s control center.
The melon allows the whale to use echolocation, which is a process that allows them to “see” sounds underwater. It works like this:
- A whale makes a sound which travels through air or water
- The sound bounces off an object and creates an echo
- The echo travels back to the whale which analyzes the timing, loudness, and pitch
- The whale then determines the size, shape, distance, and movement of the object!
8) Beluga Whales are very Vocal
Belugas are one of the most vocal whale species. Known as “sea canaries”, they communicate with chirps, clucks, squeals, squeaks, and trills. Mothers and calves “purr” softly to stay in touch.
These vocalizations play a crucial role in social interactions, mating, and navigating through their Arctic habitat.
9) Beluga Whales are Born Grey
Beluga Whales are born the color grey. As they grow older, the gene that produces melanin gradually decreases and they lighten.
Females turn completely white by age 14 and males by age 18. This is a natural adaption so that they will blend in with their icy surroundings.
In addition, Beluga Whales shed their skin every year, which contributes to their gradual whitening. In the winter, their skin thickens and turns yellowish, especially on their backs and fins. Then in the summer, they rub against gravel to remove skin and once again become white.
10) Beluga Whales are Pregnant for 14 Months
Beluga Whales are pregnant for 14 months, which is similar to other whales. (Compare this to 9 months for humans).
Breeding occurs in the spring and calves are born in the summer. Depending on the location, calves are born from March to September.
Amazingly, when a female Beluga is in labor, several other females act as midwives to help during the birth! Mothers give birth to a single calf.
11) Beluga Calves Nurse for up to One Year
Beluga calves rely on their mother’s milk for nourishment during their early stages of life. They nurse for up to one year, receiving essential nutrients from their mother’s milk. Some calves may nurse for up to two years.
12) Female Belugas Give Birth to a Calf Every 3 Years
Female Belugas give birth to a single calf every three years. By spacing out births, females can devote adequate time and attention to each calf. Also, females get sufficient time to recover and regain their strength between reproductive cycles.
13) Female Belugas Mature at 8-10 Years Old
Female Belugas reach sexual maturity when they are about 8-10 years old. Males mature slightly later. However, some female Belugas can reach sexual maturity as early as 4 years old.
14) Beluga Whales do NOT have a Dorsal Fin
Unlike most whales, Beluga Whales do not have a Dorsal Fin, which is an appendage on the back that aids in steering and balancing.
The reason for this is natural selection. If Beluga Whales had a dorsal fin, they would lose body heat and the fin would be prone to injury from floating ice.
Instead, Beluga Whales have a Dorsal Ridge, which is a raised area that runs along the back. Made out of toughened tissue and cartilage, a Dorsal Ridge helps break through ice to create breathing holes.
15) Beluga Whales have Flexible Necks
Beluga Whales are known for their remarkable flexibility. They are the only whale that has an unfused cervical vertebrae.
As a result, they have a flexible neck which allows them to nod and turn their heads in all directions. to navigate shallow waters and hunt for food.

16) Beluga Whales have Excellent Hearing
Like dolphins, Beluga Whales see with sound. They use echolocation to find food and to find their way. By sending out sounds and listening to echoes, they locate prey and learn about objects around them.
Belugas have a well-developed sense of hearing. They can hear sounds within the range of 1.2-120 kHz, with the greatest sensitivity between 10-75 kHz. In contrast, the humans hearing range is 0.02-20 kHz, which is 5 times smaller.
17) Beluga Whales are Very Friendly
Beluga Whales are known to be very social and friendly animals. They often approach boats and interact with humans. This curiosity and a friendly temperament sets them apart from other whale species.
These marine mammals form close-knit social groups called pods, where they engage in playful behaviors and communicate with each other. Belugas have been observed engaging in friendly behavior towards other species as well.

18) Beluga Whales Molt
Beluga Whales molt each summer. They travel to shallow areas and rub their bodies against stony sea beds to shed their outermost layer of skin. During molting, skin grows about 100 times faster than normal.
Molting helps Beluga Whales maintain healthy skin by removing old, dead cells and potential parasites.
19) Beluga Whales have a thick Layer of Blubber
Temperatures in the Arctic drop significantly below freezing. Beluga Whales have adapted with a layer of blubber that is 4 inches thick. And their skin is 100 times thicker than land-dwelling mammals.
A beluga’s blubber is 40% of their weight. It serves as insulation, helping them to retain heat in cold Arctic waters.
20) Belugas are Closely Related to Narwhals
Beluga Whales are related to a small, single tusked whale known as a Narwhal. Both belong to the Monodontidae family of toothed whales.
Both Belugas and Narwhals inhabit the icy waters of the Arctic and subarctic regions. They share similar ecological niches and prey on fish, squid, and other small marine creatures.

21) Beluga Whales are Slow Swimmers
Belugas are fairly slow swimmers. They commonly swim about 3-9 kph (1.9-5.6 mph). However, they are capable of sustaining a maximum speed of 22 kph (13.6 mph) for as long as 15 minutes.
Despite their slower swimming abilities, belugas are highly maneuverable and can navigate through icy Arctic waters with ease.

22) Beluga Whales can Swim Backward
Belugas are the gymnasts of the ocean. They can swim both forward, backward, and even upside down! This allows them to navigate through tight spaces in their Arctic and subarctic habitats with ease.
23) Belugas Live Together in Pods
Beluga whales live together in groups called pods. Beluga pods have a very wide range in terms of their size. They can comprise just a couple of whales, or they can be several hundred whales strong.
The average is about ten, or a range of between 2 and 25 individuals, but some groups have been spotted with more than 2000 individuals. Living in pods allows belugas to communicate, hunt, and navigate their Arctic and subarctic habitats.

24) Beluga Whales can Swim under the Ice
A Beluga Whale’s entire life is connected to sea ice. They can swim under the ice to breathe through gaps with raised blowholes.
Swimming under the ice provides belugas with access to prey and protection from predators. Their 1.5-foot blubber layer keeps them warm.
25) Beluga Whales eat 60 pounds of Food a Day
Beluga Whales eat a lot! In fact, an adult Beluga can consume up to 3-4% of its body weight each day. And this is quite a substantial amount of food!
They typically prey on bottom-dwelling creatures. And consume a diverse diet consisting of fish, crustaceans, squid, and octopus.

26) Beluga Whales Migrate in Autumn
Beluga Whales are known for their seasonal migrations. They often travel hundreds or even thousands of miles between their summer and winter habitats.
In autumn, they move south as the ice forms in the Arctic. In spring, they return to their northern feeding areas when the ice breaks up. In winter they inhabit ice-covered, deeper waters to feed on Arctic cod.
In the summer months, belugas are commonly spotted near river mouths, where they may even venture upstream. These shallow, warmer waters, such as in Canada’s Churchill or Mackenzie Rivers, provide ideal locations to feed, give birth to calves, and molt their skin.
27) Beluga Whales are Amazing Divers
Beluga Whales are amazing divers! When they dive deep, their ribs collapse (!), squeezing their lungs and helping them save oxygen.
This clever adaptation lets them stay underwater longer, making them super efficient hunters in the chilly Arctic seas.

28) Beluga Whales use their Tails to Propel through Water
The tail of a Beluga Whale is called a fluke. Like all whales, Belugas propel through water by flapping their fluke up and down. In contrast, fish swim by moving their tails horizontally.
