Captain Nemo observed the herd of cetaceans cavorting on the waters a mile from the Nautilus. “They’re southern right whales,” he said. “There goes the fortune of a whole whaling fleet.” “Well, sir,” the Canadian asked, “couldn’t I hunt them, just so I don’t forget my old harpooning trade?” “Hunt them? What for?” Captain Nemo replied. “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.”

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.”
