The International Whaling Commission (IWC) is an international organization responsible for whaling and cetacean protection. After commercial whaling led to a sharp decline in whale population, the International Whaling Commission decided to take action to protect whales. Among them, the Convention against Whaling came into effect in 1986, and the Indian Ocean Whale Sanctuary and the Southern Ocean Whale Sanctuary were established in 1979 and 1994 respectively.
However, since 1986, some countries, such as Japan and Norway, have taken advantage of the loopholes in the resolution of the International Whaling Commission to kill at least 25,000 whales or dolphins every year under the banner of "scientific whaling".
Other countries that kill whales are Norway, Iceland and Japan, as well as some indigenous tribes in Siberia, Alaska and northern Canada.

Secondary classification of cetaceans:
Modern cetaceans are divided into baleen cetaceans and toothed cetaceans, both of which evolved from ancient cetaceans and differentiated in the early Oligocene 34 million years ago. In fact, archaea is a joint group, which includes the recent ancestors of extinct ancient whales, but does not include all the descendants of their recent ancestors (that is, modern whales)
There are not many species of baleen whales, about 15 species, which belong to 4 families: Right Whale Family, Neobaleen Whale Family (or Little Right Whale Family), Baleen Whale Family and Gray Whale Family.
There are about 75 species of odontidae, which belong to 9 families: Rachytidae, Pethyridae (Brachyridae), Eupolyphaga (Freshwater Dolphinidae), Oral Cetacidae (Noctuidae), Subrachyridae, Prairie Rabbit, Dolphinidae, Narwhalidae (Narwhalidae).
