It can be found in every ocean in the southern hemisphere, residing in Antarctic waters in the summer months and northern waters in the winter months, where its range overlaps that the smaller common minke whale.

Blue Whales were abundant in most oceans around the world until the beginning of the twentieth century. For the first 40 years of the twentieth century they were hunted by whalers almost to extinction. Hunting of the blue whale was outlawed by the...

They prefer tropical warm waters to the polar seas that other whales in their family prefer. They are largely coastal whales and their diet is composed almost entirely of fish. There appear to be two species, and some confusion between the two exists. Bryde's Whales are very similar in appearance to Sei Whales and almost as...
