[101] Now gnaws the boneless polypus his feet.] Athenæus, book vii. explodes the notion of the polypus gnawing its own feet, and states that its feet are so injured by the congers or sea-eels. Pliny accounts for the mutilation in rather a marvellous manner. “They are ravenously fond of oysters: these, at the touch, close their shell, and cutting off the claws of the polypus take their food from their plunderer. The polypi, therefore, lie in wait for them when they are open; and placing a little stone, so as not to touch the body of the oyster, and so as not to be ejected by the muscular motion of the shell, assail them in security and extract the flesh. The oyster contracts itself, but to no purpose, having been thus wedged open.” Lib. ix. c. 30.
The same story has been told, with greater probability, of the monkey. “The name of polypi has been peculiarly ascribed to these animals by the ancients, because of the number of feelers or feet of which they are all possessed, and with which they have a slow progressive motion: but the moderns have given the name of polypus to a reptile that lives in fresh water, by no means so large or observable. These are found at the bottom of wet ditches, or attached to the under-surface of the broad-leaved plants that grow and swim on the waters. The same difference holds between these and the sea-water polypi, as between all the productions of the land and the ocean. The marine vegetables and animals grow to a monstrous size. The eel, the pike, or the bream of fresh waters is but small: in the sea they grow to an enormous magnitude. It is so between the polypi of both elements. Those of the sea are found from two feet in length to three or four: and Pliny has even described one, the arms of which were no less than thirty feet long. The polypus contracts itself more or less in proportion as it is touched, or as the water is agitated in which they are seen. Warmth animates them, and cold benumbs them: but it requires a degree of cold approaching congelation, before they are reduced to perfect inactivity. The arms, when the animal is not disturbed, and the season is not unfavourable, are thrown about in various directions in order to seize and entangle its prey. Sometimes three or four of the arms are thus employed; while the rest are contracted, like the horns of a snail, within the animal’s body. It seems capable of giving what length it pleases to these arms: it contracts and extends them at pleasure; and stretches them only in proportion to the remoteness of the object it would seize. Some of these animals so strongly resemble a flowering vegetable in their forms, that they have been mistaken for such by many naturalists. Mr. Hughes, the author of the Natural History of Barbadoes, has described a species of this animal, but has mistaken its nature, and called it a sensitive flowering plant. He observed it to take refuge in the holes of rocks, and, when undisturbed, to spread forth a number of ramifications, each terminated by a flowery petal, which shrunk at the approach of the hand, and withdrew into the hole from which it had before been seen to issue. This plant, however, was no other than an animal of the polypus kind: which is not only to be found in Barbadoes, but also on many parts of the coast of Cornwall, and along the shores of the Continent.” Goldsmith, Animated Nature, vol. vi.
The Polypus is mentioned by Homer, Odys. v.:
As when the polypus enforced forsakes
His rough recess, in his contracted claws
He gripes the pebbles still to which he clung:
So he within his lacerated grasp
The crumbled stone retain’d, when from his hold
The huge wave forced him, and he sank again.
