Have you ever seen a Dall Porpoise? Maybe you've heard of a Humpback Whale. These are two of the strangest marine mammals. First, let's talk about the Dall Porpoise. No, I'm not talking about the kind of "doll" you would dress up or play with. I'm talking about the kind that swims.

    Did you know that part of their name (porpoise) stands for six species of a small whale that is closely related to dolphins. They are smaller than dolphins and have cone like heads and don't have a dolphin's beak or snout. These porpoises don't leap out of the water like dolphins do, but they do sort-of roll
around in the water. Also, they come up four times a minute to breathe. Porpoises grow from 1.2 to 2 meters long and are bluish-black on the top and white on the bottom and the Dall Porpoise has white underbelly markings that you could see very clearly when it comes up on its side. The Porpoises live in
the waters of the North Pacific and sometimes in the waters near Japan.

    Back a long time ago when ships were made of wood, the seaman on the ships would hear the beautiful songs of the Humpback whale. Then the diesel and the steam engines would cut out the whales sounds until only a few sailors knew of the whales songs. Then people began to record the Humpback's
singing but by that time the Humpback whales were almost extinct. Humpback whales are filter feeding whales. That means that they are like vacuums and they suck up plankton(or tiny microscopic fish).When they migrate, they go to the Arctic and Antarctic oceans when summer comes to those regions. The Humpback whale's average length is 48 feet.
