How many whales are there in the world?

Half a century ago, there were about 300,000 blue whales in the world, and by 1974 there were 25,000, and now there are only about 2,000 left. Although there have been international limits on the number of blue whales that can be killed each year since 1932, the prospects for the world's largest animal remain dangerous. Blue Whale Alias:

Razor whales and white fin whales are the largest species of baleen whales, the longest being a female whale caught in Antarctic waters between 1904 and 1920, with a length and a weight of 170 tons. The heaviest whale was a long female whale caught off the coast of South Georgia on March 20, 1947, weighing 190 tons. The blue whale is not only the largest cetacean, but also larger than the largest dinosaur ever lived on Earth, and is the largest of all animals known to have lived since ancient times, with a general body length of 2,400-3,400 centimeters and a weight of 150,000-200,000 kilograms, that is, its weight is equivalent to the weight of more than 25 African elephants, or the weight of 2,000-3,000 people combined.

1. The latest research results of scientists have found that the world's smallest whale "Wajita" is in a very difficult living environment, and if it is not saved, this species of whale will face extinction.

2. The largest whale in the world is the blue whale, a blue whale can be long and weigh up to 195 tons, which is equivalent to the weight of 35 elephants, and a tongue alone can weigh about 3 tons.

Whales: The name of cetaceans in marine mammals, which are divided into toothed cetaceans and baleen cetaceans, and the cetaceans include the dolphin family under the cetaceans.

But it's tough and strong.

2. Baleen whales: whales with baleen whales. For example, blue whales, gray whales, and fin whales are generally 15 to 20 meters long, but in fact these long whiskers are chamfered teeth that grow inside the mouth, which are used to filter water and catch shrimp and other small animals eaten by whales, and these teeth replace the teeth.
