The floor of the cove was uneven, by reason of small, shell-covered rocks and stones being strewn over it at haphazard. From under the slightly overhanging base of one of these stones sprouted what seemed a cluster of yellowish gray, pink-mottled weed-stems, which sprawled out inertly upon the mottled bottom. Over the edge of the stone came swimming slowly one of the gold-and-azure fish, its jewelled, impassive eyes on the watch for some small prey. Up from the bottom, swift as a whip-lash, darted one of those inert-looking weed-stems, and fastened about the bright fish just behind the gills. Fiercely the shining one struggled, lashing with tail and fins till the water swirled to a boil over the shell-covered rock, and the sea-anemones all about shut their gorgeous, greedy flower-cups in a panic. But the struggle was a vain one. Slowly, inexorably, that mottled tentacle curled downward with its prey, and a portion of the under side of the rock became alive! Two ink-black eyes appeared, bulging, oval, implacable; and between them opened a great, hooked beak, like a giant parrot's. There was no separate head behind this gaping beak, but eyes and beak merely marked the blunt end of a mottled, oblong, sac-like body. [Illustration: "And the writhing tentacles composed themselves once more to stillness upon the bottom, awaiting the next careless passer-by."] As the victim was drawn down to the waiting beak, among the bases of the tentacles, all the tentacles awoke to dreadful life, writhing in aimless excitement, although there was no work for them to do. In a few seconds the fish was torn asunder and engulfed--those inky eyes the while unwinking and unmoved. A darker, livid hue passed fleetingly over the pallid body of the octopus. Then it slipped back under the shelter of the rock; and the writhing tentacles composed themselves once more to stillness upon the bottom, awaiting the next careless passer-by. Once more they seemed mere inert trailers of weed, not worth the notice of fish or crab. And soon the anemones near by reopened their treacherous blooms of yellow and crimson.
