The whale's hind limbs have degenerated (except archaea). The forelimb evolved into a caudal fin, which is convenient to move in the water. There is a species whose dorsal fin is made of skin. A whale's dorsal fin has no bones. Because of the buoyancy of water, their ribs are very fragile and have no external ears. Whales have developed brains and are very clever.

Among them, the sperm whale is one-third the length of the whole body and has the largest known brain, weighing 7 kg [1]. The bottlenose dolphin is the cleverest, and its IQ can be as high as three years old.

Protection [Editor] Most whales are endangered species and may become extinct. It's just a small number. Because of poor reproductive ability, only one child can be born, and it is tolerant in the growing period, and tolerance can mature first. Coupled with the excessive killing of human beings, the chances of survival are even more slim. Although many countries have established organizations to protect their native whales, it doesn't matter whether this is their own territory or not.

At present, few environmental organizations protect whales, including Greenpeace, WDCS and IFAW.

(Marine Guardian of Greenpeace International said that humans and other organizations do not understand the importance of protecting whales.

There are about 65,438+06 species of cetaceans and dolphins recorded in Hong Kong. Except for the Chinese white dolphins that settled in Hong Kong waters, most of them were stranded or accidentally invaded. All marine mammals in Hong Kong are protected by law.

Whaling [Editor] Text: Whaling

Bowhead whales can be divided into scientific whaling and commercial whaling. Scientific research is to do research by catching returning whales; Commercial whaling is to catch whales for food.

At present, the International Whaling Commission (IWC) has banned all commercial whaling, but Japan, Norway and Iceland all kill whales on the grounds of scientific research. In fact, they kill whales for food, which is commercial whaling. Using this rule (la3), Japan has successfully whaled 4 1 time.

Japan has re-used whale meat as a lunch box for students, hoping that the new generation of Japanese will eat more whales, and the production of Japanese whale meat will be profitable, which has aroused the disgust of biologists and whale fans.

June 5438+October 2006 10, Greenpeace tried to go to sea to stop the Japanese Whale Research Institute, which gave in and collided with the whaling ship "Jingwan 1" in Greenpeace. さ( 1230) Yuxinwan No.2 sprayed water on the staff in Greenpeace, and fishermen sprayed whale blood on the staff in Greenpeace. Because of this rotten ship, Greenpeace had to go to the whole ship, which enabled the cetacean research institute to successfully capture 845 whales, some of which were protected species.

On June 5438+065438+1October 15, 2006, Japan sent six whaling ships to the South Pole to catch 945 whales, 935 minke whales were buried with 10 fin whales, and it was good to catch 50 humpback whales, but because of the whaling ships,

In 2008, Japan plans to catch 1000 whales in Antarctica and bury 50 humpback whales in Australian waters. Australia strongly opposes it. Japan says Australia discriminates against the Japanese because whaling is the "culture" of the Japanese. With the popularity of Japanese institutions, whaling has become a Japanese culture. It is said that anyone who opposes whaling is racist against the Japanese. In 2008, it was even said that Australia discriminated against Japan. [2]

Greenpeace Forum Greenpeace Forum, there is a whale forum.

Whaling TV channel has movies buried with Greenpeace TV, including movies such as ship collision and whaling process.

The secret website of Ocean Australia was opened in Chinese or Cantonese by the moderator of Greenpeace International Forum (the main audience is teenagers, so the tone is more colloquial and simple).

Protecting the ocean TV channel has links of spraying blood and anti-ship.

None of the whaling activities has a Chinese version, which contains information about whales and whaling, and there are many signature activities.
