The Blue whale is, and always has been, the largest animal ever to exist on earth. This whale can grow to a length of 33m (110ft) and weigh 190 tons but on the average it is much smaller. The Blue whale is called a "rorqual" a Norwegian word for "furrow" and refers to the pleated grooves running from its chin to its navel. The throat grooves, in addition to streamlining the shape of the whale, allow the throat area (cavum vent-rale) to expand tremendously during feeding, and can hold 1,000 tons or more of food and water when fully expanded. By taking tonnes of water into its mouth and filtering out the fish or krill with its baleen plates a medium-sized Blue whale can eat over 4 tons of krill a day.A Humpback Whale breaches in Kenai Fjords National Park, Alaska. The humpback whale, an endangered species, is found principally in the North Atlantic and North Pacific Oceans.

2. A whaling ship.
3. A whaleboat.A song：The Whaler's Dues
Money speaks. Soft hearts lose. The truth only whispers.
It's the whaler's dues.
I've been running on diesel. Been running on coal.
Running on borrowed time, if truth's to be told.
Two whales in the ocean, cruising the night
search for each other before we turn out their light.
Been accused of deep murder on the North Atlantic swell
but I have three hungry children and a young wife as well.
And behind stand generations of hard hunting men
who raised a glass to the living, and went killing again.
Are you with me?
Money speaks, soft hearts lose. The truth only whispers.
Now pay the whaler's dues.
Can you forgive me?
Now I'm old and I sit land-locked in a back-country jail
to reflect on all of my sins and the death of the whale.
Send me back down the ages. Put me to sea once again
when the oceans were full --- yes, and men would be men.
Can you forgive me?
