Gradually, other people whaling too, spearing, harpooning,shooting, and netting whales for profit. By the middle of the century, so many whales had been killed that several kinds of whales were in danger of dying out forever. At last some people realized what terrible damage they were doing to the world's whales. Many countries have now cut down or stopped various types of whaling. But these amazing marine mammals are still threatened by hunting, overfishing, and pollution.
Whales eat certain kinds of squid, which are a reddish-pinkish color.
They have more protein in them than other squid do. They also eat fish that live in schools. Whales eat them because the bones give them calcium. They eat squid but they are so quick, whales have to be fast to catch them. Toothed whales have to be even quicker to catch them and hold on to them because squid are fast swimmers with wriggly, squirming bodies.
