The shellfish Meleagrina, that womb for pearls whose valves are nearly equal in size, has the shape of a round shell with thick walls and a very rough exterior. Some of these shells were furrowed with flaky, greenish bands that radiated down from the top. These were the young oysters. The others had rugged black surfaces, measured up to fifteen centimeters in width, and were ten or more years old. Captain Nemo pointed to this prodigious heap of shellfish, and I saw that these mines were genuinely inexhaustible, since nature’s creative powers are greater than man’s destructive instincts. True to those instincts, Ned Land greedily stuffed the finest of these mollusks into a net he carried at his side. But we couldn’t stop. We had to follow the captain, who headed down trails seemingly known only to himself. The seafloor rose noticeably, and when I lifted my arms, sometimes they would pass above the surface of the sea. Then the level of the oysterbank would lower unpredictably. Often we went around tall, pointed rocks rising like pyramids. In their dark crevices huge crustaceans, aiming their long legs like heavy artillery, watched us with unblinking eyes, while underfoot there crept millipedes, bloodworms, aricia worms, and annelid worms, whose antennas and tubular tentacles were incredibly long. Just then a huge cave opened up in our path, hollowed from a picturesque pile of rocks whose smooth heights were completely hung with underwater flora. At first this cave looked pitch-black to me. Inside, the sun’s rays seemed to diminish by degrees. Their hazy transparency was nothing more than drowned light. Captain Nemo went in. We followed him. My eyes soon grew accustomed to this comparative gloom. I distinguished the unpredictably contoured springings of a vault, supported by natural pillars firmly based on a granite foundation, like the weighty columns of Tuscan architecture. Why had our incomprehensible guide taken us into the depths of this underwater crypt? I would soon find out. After going down a fairly steep slope, our feet trod the floor of a sort of circular pit. There Captain Nemo stopped, and his hand indicated an object that I hadn’t yet noticed. It was an oyster of extraordinary dimensions, a titanic giant clam, a holy-water font that could have held a whole lake, a basin more than two meters wide, hence even bigger than the one adorning the Nautilus’s lounge. I approached this phenomenal mollusk. Its mass of filaments attached it to a table of granite, and there it grew by itself in the midst of the cave’s calm waters. I estimated the weight of this giant clam at 300 kilograms. Hence such an oyster held fifteen kilos of meat, and you’d need the stomach of King Gargantua to eat a couple dozen.
