A. Swimming. Generally, silk dolphins are swimmers. They are usually swimming about 3 - 9 km (1.9 - 5.6 mph) per hour. However, they were able to maintain a maximum speed of 22 km / h (13.6 mph) for up to 15 minutes (Nowak, 1991; Ridgway and Harrison, 1981). Beluga whale can swim back and forth (Nowak, 1991). Blue blue whale swim in a depth that only barely covers the body (Ridgway and Harrison, 1981). B. Diving Beluga does not normally sneak into the ground. It is usually about 20 meters (66 feet).
The name Beluga comes from the Russian "Bielo". Blue whale inhabits several sheaths, hunts and passes to hundreds of whales. Beluga is very sociable. In the summer, it is often seen near the mouth of the estuary, sometimes at upstream (621.4 miles (1000 km) of the Yukon River). However, recent survey of satellite markings shows that spider dolphins spend in the ocean and dive into the depth of at least 1,148 feet (350 m), where they can become prey for deep sea.
Blue whale is a whale with adult white teeth. The blue whale has a small mole, a small blunt head with small eyes and thick exquisite meat. White Russian means "white" in Russian. The blue whale is also called Beluga. The blue whale has an average length of about 15 feet and weighs about 3,300 pounds. Beluga is a sociable animal that tends to kill and move in a sheath of about 10 whales. The blue whale lives in a cold Arctic Ocean and a subarctic ocean, but some people move from the south to the warmer seas during the summer. At the same time, the whales also enter the salt water (partial salt water) along the north river and hunt the prey. Killer whales and polar bears prey on white millet, especially calves. For centuries people have been looking for white whales, but now only a few Arctic tribes are hunting them. It is estimated that there are about 40,000 to 80,000 whales in the world. St. Lawrence's Beluga is in great danger
Due to hunting habits, the population of some white whales has drastically declined. Historically, numerous silkworms have been commercially hunted. Today only suicide hunting is allowed in the waters of the United States. Since humans change coastlines and estuaries by pollution, dams, offshore oil exploration and mining, the affinity of the blue whale against shallow coastal water is at risk. Canada's St. Lawrence estuary is an example of high pollution due to industrial pollution.
The population of St. Lawrence Beluga found along the St. Lawrence River in eastern Canada is the southernmost point of this species and is geographically separated from other Beluga populations. Beluga is also located along the northern coast of Alaska, the Arctic Ocean in northern Canada, and along the Hudson Bay.
