Are beluga whales extinct now and why are whales extinct

Beluga. There is no extinction.

Beluga whales are now very scarce, but under artificial breeding, they are still not extinct, and now some aquariums.

There's also beluga whale in it. Therefore, the beluga whale is not extinct.

Beluga whale is a relatively small toothed whale Brown and gray at birth Bright white when adult The adult beluga whale is about five meters long It is the only cetacean with a movable neck that can move its head up and down, left and right Beluga whales live in the Arctic Ocean and adjacent seas and feed on fish Natural predators are other cetaceans Sharks Polar bears, etc. Beluga whales are not extinct But scientists believe that they are on the verge of extinction So they must be protected.

Platinum, also known as Greenland whales, as early as the 60s of the last century, due to a large number of human hunting for boiling whale oil, its number was greatly reduced to the 90s, almost disappeared, and finally, was judged extinct by the United Nations.

Due to the large number of human killings, the number of beluga whales has plummeted.

The living environment of the beluga whale has been damaged, and the beluga whale has died one after another.

It is on the verge of extinction.

Beluga whales are also known as Greenland whales. As early as the 60s of the last century, due to the large number of human hunts used to boil whale oil, its number was greatly reduced to the 90s, and his activity almost disappeared, and the United Nations judged it to be extinct.

Beluga whales are not extinct and are key protected animals.

Whales have poor reproductive capacity, giving birth to a calf in an average of two years. Due to human hunting and pollution of the oceans, the number of whales has decreased dramatically. For example, the largest of the cetaceans, the blue whale, was killed in the 20th century, with nearly 360,000 whales killed in the 20th century, and many species of whales that have lived on the earth for more than 50 million years, many species are on the verge of extinction.

The body structure and living habits of cetaceans are obviously different from those of any mammal, so they have been listed as a single order for a long time. Its ancestry and evolutionary history were once controversial, but with the continuous progress of related research, it has been fully confirmed that cetaceans evolved from terrestrial artiodactyls 50 million years ago.

DNA sequencing showed that cetaceans and hippos were sister groups, and their clades were sister groups to ruminants. In order to avoid artiodactyls becoming a paraphyletic group (i.e., missing part of the evolutionary clades), the current classification classifies cetaceans as artiodactyls and downgrades them to subcetaceans.

Whales have poor reproductive capacity, giving birth to a calf in an average of two years. Many species are on the verge of extinction due to humans slaughtering whales on Earth for more than 50 million years. In general, it is humans who hurt them.

Blue whales are not extinct yet and are found in all four oceans, but in smaller numbers, and were added to the Red List of Endangered Species in 2012. Blue whales typically feed at depths of more than 100 metres during the day and only come to the surface at night, while females typically give birth every 2 to 3 years.

The blue whale is a marine mammal with four subspecies. Blue whales are considered to be the largest known living animals on Earth, measuring about 22 to 33 meters in length and weighing around 150 to 180 tons.

The blue whale has a slender body with a pale blue or rat-gray color all over the body, although it can sometimes be lighter in the water, with pale fine markings on the back and white spots on the chest.

The dorsal fin of the blue whale is particularly short, the tail is broad, flattened, and the whole body is streamlined, which looks like a razor, so it is also called the razorwhale.

The dragon whale was extinct in the late Eocene more than 30 million years ago. The dragon king whale, scientific name, basilosaurus, meaning emperor lizard, also known as the robot-toothed whale, is an extinct ancient marine mammal, a close relative of the modern whale, a species of cetaceans that lived in the late Eocene between 39 million and 34 million years ago.

Initially mistaken for a giant marine reptile fossil, Zhen was named the emperor lizard, which was first discovered in Louisiana, USA, and then paleontologists identified at least two other species from fossils found in Egypt and Pakistan.

The dragon whale is one of the known primitive cetaceans, which evolved from land animals, and then further evolved into the modern cetaceans of the two royal blade species.

Although a species of whale, the dragon whale resembles a giant sea serpent, and when it was first discovered, paleontologists thought it was a reptile.
