The “Argonaut,” or “Paper Sailor,” is no less beautiful and interesting than the Pearly Nautilus. The thin and fragile shell cannot be compared with that of the Nautilus nor with the pen, or internal support, of the squid, for it is attached to the animal by no muscles, and is only kept in position by the broad webs on the upper arms of the female (which alone possesses a shell), its function being simply to protect the eggs. The male is very much smaller than the female and is exceedingly rare. The natural position of the female is with its arms spread out and hanging about the shell, four in front and four behind, the two broad arms supporting the shell being spread out and closely embracing the latter. The siphon is turned toward the ridged part of the shell and the animal progresses in a backward direction by forcibly ejecting water through this organ. It crawls with the shell on its back, like a snail. The poets have given us many beautiful writings detailing the vices and virtues of the lower forms of life and among these the Pearly Nautilus and Paper Sailor have received a goodly share of the muse’s attention. But, alas! for the poet, who, not being a conchologist, has sadly misused and misjudged these helpless and harmless creatures. Thus we are told how the paper nautilus sails over the ocean with his “sails” (meaning the two expanded arms) spread out to catch the breeze, and how, when the storm approaches, it folds its sails and disappears beneath the waters of the ocean. Alas for the poet! he puts the most beautiful ideas together in verse, ideas and themes which we would fain believe; but along comes cold, calculating science, and at one fell stroke sweeps away all that the poet has done, for in the poem on the Argonaut all is wrong, the animal does not and could not sail, for were it to do so the shell would fall and become lost in the bottom of the ocean.
