During the course of the next day, April 12, the Nautilus drew near the coast of Dutch Guiana, by the mouth of the Maroni River. There several groups of sea cows were living in family units. These were manatees, which belong to the order Sirenia, like the dugong and Steller’s sea cow. Harmless and unaggressive, these fine animals were six to seven meters long and must have weighed at least 4,000 kilograms each. I told Ned Land and Conseil that farseeing nature had given these mammals a major role to play. In essence, manatees, like seals, are designed to graze the underwater prairies, destroying the clusters of weeds that obstruct the mouths of tropical rivers.

“And do you know,” I added, “what happened since man has almost completely wiped out these beneficial races? Rotting weeds have poisoned the air, and this poisoned air causes the yellow fever that devastates these wonderful countries. This toxic vegetation has increased beneath the seas of the Torrid Zone, so the disease spreads unchecked from the mouth of the Rio de la Plata to Florida!”

And if Professor Toussenel is correct, this plague is nothing compared to the scourge that will strike our descendants once the seas are depopulated of whales and seals. By then, crowded with jellyfish, squid, and other devilfish, the oceans will have become huge centers of infection, because their waves will no longer possess “these huge stomachs that God has entrusted with scouring the surface of the sea.”

Meanwhile, without scorning these theories, the Nautilus’s crew captured half a dozen manatees. In essence, it was an issue of stocking the larder with excellent red meat, even better than beef or veal. Their hunting was not a fascinating sport. The manatees let themselves be struck down without offering any resistance. Several thousand kilos of meat were hauled below, to be dried and stored.

The same day an odd fishing practice further increased the Nautilus’s stores, so full of game were these seas. Our trawl brought up in its meshes a number of fish whose heads were topped by little oval slabs with fleshy edges. These were suckerfish from the third family of the subbrachian Malacopterygia. These flat disks on their heads consist of crosswise plates of movable cartilage, between which the animals can create a vacuum, enabling them to stick to objects like suction cups.

The remoras I had observed in the Mediterranean were related to this species. But the creature at issue here was an Echeneis osteochara, unique to this sea. Right after catching them, our seamen dropped them in buckets of water.

Its fishing finished, the Nautilus drew nearer to the coast. In this locality a number of sea turtles were sleeping on the surface of the waves. It would have been difficult to capture these valuable reptiles, because they wake up at the slightest sound, and their solid carapaces are harpoon–proof. But our suckerfish would effect their capture with extraordinary certainty and precision. In truth, this animal is a living fishhook, promising wealth and happiness to the greenest fisherman in the business.

The Nautilus’s men attached to each fish’s tail a ring that was big enough not to hamper its movements, and to this ring a long rope whose other end was moored on board.

Thrown into the sea, the suckerfish immediately began to play their roles, going and fastening themselves onto the breastplates of the turtles. Their tenacity was so great, they would rip apart rather than let go. They were hauled in, still sticking to the turtles that came aboard with them.

In this way we caught several loggerheads, reptiles a meter wide and weighing 200 kilos. They’re extremely valuable because of their carapaces, which are covered with big slabs of horn, thin, brown, transparent, with white and yellow markings. Besides, they were excellent from an edible viewpoint, with an exquisite flavor comparable to the green turtle.

This fishing ended our stay in the waterways of the Amazon, and that evening the Nautilus took to the high seas once more.
