Twenty Thousand Leagues Under the Seas – Day 76 of 165

It was eight o’clock in the morning. By 8:30 we were suited up for this new stroll and equipped with our two devices for lighting and breathing. The double door opened, and accompanied by Captain Nemo with a dozen crewmen following, we set foot on the firm seafloor where the Nautilus was resting, ten meters down.

A gentle slope gravitated to an uneven bottom whose depth was about fifteen fathoms. This bottom was completely different from the one I had visited during my first excursion under the waters of the Pacific Ocean. Here I saw no fine–grained sand, no underwater prairies, not one open–sea forest. I immediately recognized the wondrous region in which Captain Nemo did the honors that day. It was the coral realm.

In the zoophyte branch, class Alcyonaria, one finds the order Gorgonaria, which contains three groups: sea fans, isidian polyps, and coral polyps. It’s in this last that precious coral belongs, an unusual substance that, at different times, has been classified in the mineral, vegetable, and animal kingdoms. Medicine to the ancients, jewelry to the moderns, it wasn’t decisively placed in the animal kingdom until 1694, by Peysonnel of Marseilles.

A coral is a unit of tiny animals assembled over a polypary that’s brittle and stony in nature. These polyps have a unique generating mechanism that reproduces them via the budding process, and they have an individual existence while also participating in a communal life. Hence they embody a sort of natural socialism. I was familiar with the latest research on this bizarre zoophyte—which turns to stone while taking on a tree form, as some naturalists have very aptly observed—and nothing could have been more fascinating to me than to visit one of these petrified forests that nature has planted on the bottom of the sea.

We turned on our Ruhmkorff devices and went along a coral shoal in the process of forming, which, given time, will someday close off this whole part of the Indian Ocean. Our path was bordered by hopelessly tangled bushes, formed from snarls of shrubs all covered with little star–shaped, white–streaked flowers. Only, contrary to plants on shore, these tree forms become attached to rocks on the seafloor by heading from top to bottom.

Our lights produced a thousand delightful effects while playing over these brightly colored boughs. I fancied I saw these cylindrical, membrane–filled tubes trembling beneath the water’s undulations. I was tempted to gather their fresh petals, which were adorned with delicate tentacles, some newly in bloom, others barely opened, while nimble fish with fluttering fins brushed past them like flocks of birds. But if my hands came near the moving flowers of these sensitive, lively creatures, an alarm would instantly sound throughout the colony. The white petals retracted into their red sheaths, the flowers vanished before my eyes, and the bush changed into a chunk of stony nipples.

Sheer chance had placed me in the presence of the most valuable specimens of this zoophyte. This coral was the equal of those fished up from the Mediterranean off the Barbary Coast or the shores of France and Italy. With its bright colors, it lived up to those poetic names of blood flower and blood foam that the industry confers on its finest exhibits. Coral sells for as much as ₣500 per kilogram, and in this locality the liquid strata hid enough to make the fortunes of a whole host of coral fishermen. This valuable substance often merges with other polyparies, forming compact, hopelessly tangled units known as “macciota,” and I noted some wonderful pink samples of this coral.

But as the bushes shrank, the tree forms magnified. Actual petrified thickets and long alcoves from some fantastic school of architecture kept opening up before our steps. Captain Nemo entered beneath a dark gallery whose gentle slope took us to a depth of 100 meters. The light from our glass coils produced magical effects at times, lingering on the wrinkled roughness of some natural arch, or some overhang suspended like a chandelier, which our lamps flecked with fiery sparks. Amid these shrubs of precious coral, I observed other polyps no less unusual: melita coral, rainbow coral with jointed outgrowths, then a few tufts of genus Corallina, some green and others red, actually a type of seaweed encrusted with limestone salts, which, after long disputes, naturalists have finally placed in the vegetable kingdom. But as one intellectual has remarked, “Here, perhaps, is the actual point where life rises humbly out of slumbering stone, but without breaking away from its crude starting point.”

Finally, after two hours of walking, we reached a depth of about 300 meters, in other words, the lowermost limit at which coral can begin to form. But here it was no longer some isolated bush or a modest grove of low timber. It was an immense forest, huge mineral vegetation, enormous petrified trees linked by garlands of elegant hydras from the genus Plumularia, those tropical creepers of the sea, all decked out in shades and gleams. We passed freely under their lofty boughs, lost up in the shadows of the waves, while at our feet organ–pipe coral, stony coral, star coral, fungus coral, and sea anemone from the genus Caryophylia formed a carpet of flowers all strewn with dazzling gems.
