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. The battle between sperm whales and baleen whales had already begun when the Nautilus arrived. It maneuvered to cut into the herd of long-skulled predators. At first the latter showed little concern at the sight of this new monster meddling in the battle. But they soon had to sidestep its thrusts. What a struggle! Ned Land quickly grew enthusiastic and even ended up applauding. Brandished in its captain’s hands, the Nautilus was simply a fearsome harpoon. He hurled it at those fleshy masses and ran them clean through, leaving behind two squirming animal halves. As for those daunting strokes of the tail hitting our sides, the ship never felt them. No more than the collisions it caused. One sperm whale exterminated, it ran at another, tacked on the spot so as not to miss its prey, went ahead or astern, obeyed its rudder, dived when the cetacean sank to deeper strata, rose with it when it returned to the surface, struck it head-on or slantwise, hacked at it or tore it, and from every direction and at any speed, skewered it with its dreadful spur. What bloodshed! What a hubbub on the surface of the waves! What sharp hisses and snorts unique to these frightened animals! Their tails churned the normally peaceful strata into actual billows.
