Belugas have teeth, but they’re not particularly long or sharp, and they aren’t really used when scrounging along the ocean floor. Instead, the whales will suck their food in , making sure its small enough not to get stuck in their throats. When hunting fish, they Belugas will group together and herd a school of their prey into shallow waters, making it hard for them to escape.

How social are Beluga Whales?

Belugas are very social, forming pods of anywhere from 2 to 25 members (the average is 10), led by a dominant male. They are known to jump ship, switching easily to new pods. During the summer, pods join together, the thousands of Belugas forming massive groups in estuaries for calving season. Belugas are quite playful, chasing each other around for fun, spitting water at each other (and humans), rubbing up against each other, calling to each other, making toys out of objects they find in the water, and swimming up next to boats to check out the people riding inside.

How fast can Beluga Whales swim? How long can they stay underwater?

Belugas are fairly slow swimmers, usually travelling at speeds somewhere between 3 and 9km per hour. They can go up to about 20 km an hour, sustaining that speed for about 15 minutes. The deepest recorded Beluga dive was 872 metres. Most dives usually last up to 5 minutes, but Belugas can in fact stay underwater up until just shy of 20 minutes. Like other whales, Belugas reduce their heart beats from the usual 100 per minute down to somewhere between 10 and 20 in order to conserve oxygen. While in a dive, blood is diverted away from other organs to keep oxygen going to the lungs, brain, and heart, which require a constant supply.

How many Beluga Whales are there today?

The International Union for Conservation of Nature estimates that there are over 150,000 Belugas worldwide.

Why do belugas have a lower heart rate?

Like other whales, Belugas reduce their heart beats from the usual 100 per minute down to somewhere between 10 and 20 in order to conserve oxygen. While in a dive, blood is diverted away from other organs to keep oxygen going to the lungs, brain, and heart, which require a constant supply.

Why are belugas called sea canaries?

Because of their wide variety of sounds, Belugas are sometimes called “Sea Canaries.”. Belugas are one of the few members of the dolphin or whale families that can turn and nod its head. Belugas don’t have any dorsal fins (fins on their backs) which allows them to travel close to overhead ice.

What is the bulge on a beluga’s forehead called?

The big bulge on the Beluga’s forehead is called a “melon .” While all toothed whales have them (they’re used to amplify the clicks sent out for echolocation) only the Beluga can purposefully change the shape of the melon in order to create different sounds.

Why do belugas strand?

The exact cause of most stranding cases is unknown. Belugas may strand when molting avoiding predators; or avoiding other threats, such as noise and vessel traffic; when chasing prey, or when suffering from injuries or disease.

The whales send their vocalizations over thousands of miles to communicate and navigate during migration. A blue whale, for example, can take up to two minutes to sing just one note of its song. The frequency it sings at is too low to be heard by the human ear, but is one that can travel great distances through water because water is an excellent sound conductor. Emitting these sounds allows them to “see” the world around them.

How do whales communicate?

They use a form of sonar called echolocation, making clicks and pops that reflect back to them, telling them the locations of things around them.

Why do humans migrate from one place to another?

Among human beings, migrations from one place or country to the other occur due to some urgent need, but it does not do so routinely but becomes a decision of some.

What do beluga whales look like?

Born dark grey, with a bluish or brownish tinge that gets lighter with age, belugas turn pure white between 5 to 12 years of age. Beluga whales are unlike any other whale, dolphin or porpoise. A yellowish tinge can sometimes be seen on adult belugas, caused by a layer of algae growing on their skin. This yellowy hue is soon lost during summer moulting though – a rather unusual event for cetaceans – restoring them to their pearly glow. Given their choice of habitat, a beluga’s body needs to be robust and is wrapped in a thick layer of blubber. This often forms thick rubbery folds along the sides and belly, keeping them nice and warm.

Where are beluga whales caught?

Hunting – beluga whales are hunted off the coast of Greenland, Russia, Canada and the USA.

Appearance

The beluga whale is distinguished by its all-white appearance. Unlike most whales, they do not have a dorsal fin. This allows them to swim more easily under the ice and closer to the surface. Their heads feature a protuberance that holds a special organ, called a melon, that allows them to use echolocation.

Habitat

The beluga whale is most commonly found in the waters around the Arctic and sub-Arctic. During the summer, it can be found around the coast of Alaska, northern California, Greenland, and northern Russia. Their habitat only extends as far south as areas around the Shantar Islands and the Sea of Okhotsk.

Diet

Beluga whales are opportunist feeders. This means that their habits change depending on the season and their location. This is heightened by the fact that they are slow swimmers. But, they can dive to around 2,300 feet. During one period of time, they might eat Arctic cod, rosefish, or Coho salmon.

Reproduction

Scientists are not entirely sure when beluga whales reach sexual maturity. Estimates suggest sometime between nine and fifteen for males and eight and fourteen for females. According to Scientific Reports, the average age that belugas first give birth is 8.5 years old.

Threats

Beluga whales face numerous threats. This includes hunting in the Arctic, Alaska, Greenland, and Russia by native peoples. This is done for both consumption and for profit. The whales are easy to hunt due to their predictable migratory patterns. Studies suggest that around 1,000 beluga whales are killed every year.

FAQs

Toothed whales produce sounds for two overlapping functions: communicating and echolocating. Beluga whales are extremely vocal. The frequency and large repertoire of their vocalizations earned them the nickname "sea canaries". Vocalizations.

Why do beluga whales have different frequencies?

The different frequencies were thought to be a response to the amount of ambient noise in the area. Beluga whales produce directional clicks in rapid sequences called trains. The click train passes through the melon.

What is the ability of a toothed whale to discriminate?

Echolocation. The term echolocation refers to an ability that toothed whales (and some other marine mammals and most bats) possess that enables them to locate and discriminate objects by listening for echoes. Toothed whales echolocate by producing clicking sounds and then receiving and interpreting the resulting echo.

Why is it important for whales to echolocate?

For belugas, echolocation is especially important for navigating under ice fields and locating breathing holes in the ice.

How many different vocalizations are there for belugas?

Vocalizations. At least 11 different beluga vocals have been documented, including high-pitched, resonant whistles and squeals; clucks; mews; chirps; trills; and bell-like tones.

What waves do belugas make?

The sound waves produced by a beluga whale bounce off objects in the water and return to the beluga in the form of an echo. In one echolocation study, a single beluga produced signals with peak frequencies of 40 to 60 kHz in San Diego Bay, California, and 100 to 120 kHz when moved to Kaneohe Bay, Hawaii.

How do belugas communicate?

Besides vocalizations, belugas may communicate through facial expressions and physical contact. Visual behaviors such as breaches, pectoral slaps (slapping a pectoral flipper on the water’s surface), and lobtails (slapping flukes on the water’s surface) are not as common in belugas as in some other whale species.
