Why are beluga whales endangered in Canada?
Hunting is certainly the main cause of the dramatic declines in beluga populations. However, contributing factors could include alterations to habitats—such as damming of rivers—and possibly noise pollution caused by ships and pleasure craft.
What happens if belugas go extinct?
The food chain would not drop if the beluga whale became extinct. There will still be some damage done. An example is the polar bear population might go down a little bit and also the killer whale.
Where are belugas endangered?

How do beluga whales survive?
Beluga whales have many adaptations that allow them to live in extremely cold waters. They don’t have a dorsal fin, which is believed to help them survive under ice. They have round bodies and a thick layer of blubber to keep out the cold.
Why should we save beluga whales?
Why They Matter. Whales, like the beluga, are at the top of the food chain and have an important role in the overall health of the marine environment. Like polar bears, the beluga depends on sea ice for its existence and can be directly impacted by climate change.

How do beluga whales protect themselves?
Like almost every other animal, whales have a “fight or flight” response to being attacked. When being hunted by killer whales in arctic waters, belugas will use sea ice to evade their fellow cetaceans and provide barriers to help them escape.
Do belugas migrate?
Where do belugas live? Most populations of beluga migrate. 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 summer, they are often found near river mouths, and sometimes even venture up river.
How long have belugas been endangered?
2008
In 2000, NOAA Fisheries designated the Cook Inlet beluga whale population as a Candidate Species under the Endangered Species Act and as depleted under the Marine Mammal Protection Act. In 2008, the Cook Inlet beluga Distinct Population Segment (DPS) was listed as endangered under the Endangered Species Act.
How do belugas protect themselves?
The white colouration of the skin is an adaptation to life in the Arctic that allows belugas to camouflage themselves in the polar ice caps as protection against their main predators, polar bears and killer whales. Unlike other cetaceans, the belugas seasonally shed their skin.
How long can belugas live?
35 – 50 years

How dangerous are beluga whales?

Why are beluga whales extinct?
The beluga whale, also known as the “Canary of the Sea,” could become as much of a harbinger of danger as its feathered namesake. The pure white whales of Cook Inlet, Alaska are at a great risk of extinction due to fossil fuel extraction.
What are threats to beluga whales?
Potential threats to beluga whales include hunting, interaction with fisheries, stranding, entrapment in sea ice, predation, underwater noise pollution, contaminants, and climate change. Alaska Natives hunt belugas as part of their subsistence culture.
How do beluga whales protect themselves from predators?
Beluga whales defend themselves by blending in with the polar ice caps that they swim near. For example, they often swim by large white chunks of snow in the water to hide from their main predators. They also have superb hearing and distinct voices, so they can call each other for protection.
