"Simply to destroy them? We have no use for whale oil on this ship."
"But, sir," the Canadian went on, "in the Red Sea you authorized us to chase a dugong!"
"There it was an issue of obtaining fresh meat for my crew. Here it would be killing for the sake of killing. I'm well aware that's a privilege reserved for mankind, but I don't allow such murderous pastimes. When your peers, Mr. Land, destroy decent, harmless creatures like the southern right whale or the bowhead whale, they commit a reprehensible offense. Thus they've already depopulated all of Baffin Bay, and they'll wipe out a whole class of useful animals. So leave these poor cetaceans alone. They have quite enough natural enemies, such as sperm whales, swordfish, and sawfish, without you meddling with them."
I'll let the reader decide what faces the Canadian made during this lecture on hunting ethics. Furnishing such arguments to a professional harpooner was a waste of words. Ned Land stared at Captain Nemo and obviously missed his meaning. But the captain was right. Thanks to the mindless, barbaric bloodthirstiness of fishermen, the last baleen whale will someday disappear from the ocean.
Ned Land whistled "Yankee Doodle" between his teeth, stuffed his hands in his pockets, and turned his back on us.
Meanwhile Captain Nemo studied the herd of cetaceans, then addressed me:
"I was right to claim that baleen whales have enough natural enemies without counting man. These specimens will soon have to deal with mighty opponents. Eight miles to leeward, Professor Aronnax, can you see those blackish specks moving about?"
"Yes, captain," I replied.
"Those are sperm whales, dreadful animals that I've sometimes encountered in herds of 200 or 300! As for them, they're cruel, destructive beasts, and they deserve to be exterminated."
The Canadian turned swiftly at these last words.
"Well, captain," I said, "on behalf of the baleen whales, there's still time--"
"It's pointless to run any risks, professor. The Nautilus will suffice to disperse these sperm whales. It's armed with a steel spur quite equal to Mr. Land's harpoon, I imagine."
The Canadian didn't even bother shrugging his shoulders. Attacking cetaceans with thrusts from a spur! Who ever heard of such malarkey!
"Wait and see, Professor Aronnax," Captain Nemo said. "We'll show you a style of hunting with which you aren't yet familiar. We'll take no pity on these ferocious cetaceans. They're merely mouth and teeth!"
Mouth and teeth! There's no better way to describe the long-skulled sperm whale, whose length sometimes exceeds twenty-five meters. The enormous head of this cetacean occupies about a third of its body. Better armed than a baleen whale, whose upper jaw is adorned solely with whalebone, the sperm whale is equipped with twenty-five huge teeth that are twenty centimeters high, have cylindrical, conical summits, and weigh two pounds each. In the top part of this enormous head, inside big cavities separated by cartilage, you'll find 300 to 400 kilograms of that valuable oil called "spermaceti." The sperm whale is an awkward animal, more tadpole than fish, as Professor Frédol has noted. It's poorly constructed, being "defective," so to speak, over the whole left side of its frame, with good eyesight only in its right eye.
Meanwhile that monstrous herd kept coming closer. It had seen the baleen whales and was preparing to attack. You could tell in advance that the sperm whales would be victorious, not only because they were better built for fighting than their harmless adversaries, but also because they could stay longer underwater before returning to breathe at the surface.
There was just time to run to the rescue of the baleen whales. The Nautilus proceeded to midwater. Conseil, Ned, and I sat in front of the lounge windows. Captain Nemo made his way to the helmsman's side to operate his submersible as an engine of destruction. Soon I felt the beats of our propeller getting faster, and we picked up speed.
