For the Eskimos, beluga whales are also very important, not only because their meat is delicious, but their oil is not only used to light lamps, but also releases a lot of heat to keep simple igloos warm. In addition, the skin of the beluga whale is also very useful, has a fragrance, and can be made into various decorations.
The vast majority of beluga whales in the world live in the waters north of Europe, Alaska in the United States and Canada. They like to live in groups. Their whole bodies are pink and white, and they look pure and flawless. But the individual is relatively small, far less huge than the bowhead whale.
When French explorer Jacques Cartier discovered the St. Lawrence River in 1535, his fleet was greeted by beluga whales. These beluga whales sang and danced in the water, and their songs were melodious and melodious, resounding hundreds of miles away. Their beautiful and melodious sounds amazed the crew members on the ship, and they affectionately gave the beluga whales a beautiful title, "Canary in the Ocean."
Unfortunately, since the 17th century, due to the high profits of whaling, whalers have carried out crazy hunting of beluga whales, resulting in a sharp decline in the number of beluga whales. What is even more tragic is that the ecological environment of beluga whales has been destroyed, and batches of beluga whales have died one after another. Scientists found the factors that caused death after autopsies: due to a series of toxic substances, their immune systems were severely damaged, and these beluga whales suffered from gastric ulcer perforation, hepatitis, lung abscess and other diseases; more In fact, some beluga whales have developed bladder cancer, which is unheard of among cetaceans.
