Captain Nemo was obviously familiar with this bivalve's existence. This wasn't the first time he'd paid it a visit, and I thought his sole reason for leading us to this locality was to show us a natural curiosity. I was mistaken. Captain Nemo had an explicit personal interest in checking on the current condition of this giant clam. The mollusk's two valves were partly open.
This is of flat-surface rock, irregularly carpeted with coarse sand, and dotted with colonies of millions of oysters. Dead coral and other products of the sea are scattered everywhere on this plateau, and it is a theory that these surface interruptions prevent overcrowding of the oysters, and consequently assist in the bivalve's reaching the pearl-producing stage.
