What is the whale of Beluga?

Beluga whale, Delphinapterus leucas or white whale, is a small, round whale living in most of the polar rates. The whale of Beluga is closely associated with Narwhal, often called a sea canary for its high -ranking vocalization. All-White Whale has long enchanted fans and is now shown in captivity around the world. 15 months and nurse for about two years. Young animals are relieving as they grow, becoming purely white shortly after sexual maturity between seven and nine years. The Belugs use echolocation to find food and potential obstacles underwater and are reported sufficiently loud to hear above the water surface. Some observers have noted that the head of melon shaped changes in shape depending on the whistles, clicks and chirping it produces.

The whales are notorious, unlike most other types of whales. INElryba can belong to several pods or family groups in life. Adult men tend to gather together in large groups, sometimes more than a hundred animals. Females and calves remain closer to each other, although they can join several pods for traditional breeding and feeding. Some observers have noticed ripe whales that return to their birth to temporarily meet their mothers.

It is assumed that there are about 100,000 belugs in the wild. As a predator of the long -term peak, the whale of Beluga is considered an important barometer of the environmental state. Human pollution has been shown to have a manifold effect on the beluga population, with recent tests of carcasses to provide evidence of increased cancer. In one population, originally from the Canadian river St. Lawrence, dead whale bodies are considered toxic waste because they contain an extremely high level of hazardous chemicals. There is now a great concern among experts that a high level of pollution leads to sThe reproductive rate between the Beluga whale and can cause long -term damage to the population.

Beluga whales were among the first types of whales that were kept in captivity, from 1861. Since then, they have been a popular foundation of aquariums and sea life parks. The detectors claim that this practice is harmful to animals because they are used to a huge range and are under considerable stress in the tank environment. Proponents of captivity claim that allowing public interaction to be protected by animals and allows closer scientific study than wild animals observation.

For centuries, the whale of Beluga has been hunted by Inuit tribes all over Canada and Alaska. While some whale communities were not very damaged by hunting, other groups were dangerously guaranteed, leading to a seriously reduced number. The unsustainable levels of hunting and growing pollution in domestic ranges have led to several Beluga whales communities to have been mentioned as an endangered or endangered threat to Canadian and US government agencies.
