“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.
