Glaucus; Or, The Wonders of the Shore

[Picture: Plate 5: Balanophyllea Regia etc.] Next, what are those bright little buds, like salmon-coloured Banksia roses half expanded, sitting closely on the stone? Touch them; the soft part is retracted, and the orange flower of flesh is transformed into a pale pink flower of stone. That is the Madrepore, Caryophyllia Smithii (Plate V. fig. 2); one of our south coast rarities: and see, on the lip of the last one, which we have carefully scooped off with the chisel, two little pink towers of stone, delicately striated; drop them into this small bottle of sea-water, and from the top of each tower issues every half-second— what shall we call it?— a hand or a net of finest hairs, clutching at something invisible to our grosser sense. That is the Pyrgoma, parasitic only (as far as we know) on the lip of this same rare Madrepore; a little “cirrhipod,” the cousin of those tiny barnacles which roughen every rock (a larger sort whereof I showed you on the Turritella), and of those larger ones also who burrow in the thick hide of the whale, and, borne about upon his mighty sides, throw out their tiny casting nets, as this Pyrgoma does, to catch every passing animalcule, and sweep them into the jaws concealed within its shell. And this creature, rooted to one spot through life and death, was in its infancy a free swimming animal, hovering from place to place upon delicate ciliæ, till, having sown its wild oats, it settled down in life, built itself a good stone house, and became a landowner, or rather a glebæ adscriptus, for ever and a day. Mysterious destiny!— yet not so mysterious as that of the free medusoid young of every polype and coral, which ends as a rooted tree of horn or stone, and seems to the eye of sensuous fancy to have literally degenerated into a vegetable. Of them you must read for yourself in Mr. Gosse’s book; in the meanwhile he shall tell you something of the beautiful Madrepores themselves. His description, {118} by far the best yet published, should be read in full; we must content ourselves with extracts.
