What are the natural enemies of whales?

The natural enemy of whales is Japanese, and Japan is the largest whaling country.

Japan demands that more than 400 whales be killed in Antarctica for "scientific purposes". This is the third consecutive year that Japan has made a similar request to the World Whale Conservation Committee. Moreover, when Japan hunts whales in this waters, there are always some companies' ships that process the captured whales on board and then transport them to the Japanese and Korean markets. When the Japanese whaling fleet kills whales, it always puts up a huge placard on board, which reads: Take whale tissue samples.

In June+10, 5438, the Argentine Foreign Ministry issued a communique accusing Japan of killing 400 whales in the Antarctic reserve every year, calling on it to immediately stop whaling in this area.
