John Ashton, Curious Creatures in Zoology
“ These creatures are by nature a sort of fleshy branch, and are nurtured upon flesh. They have the power of producing an itching, smarting pain, just like that caused by the nettle found on land. For the purpose of seeking its prey, it contracts, and stiffens itself to the utmost possible extent, and then, as a small fish swims past, it will suddenly spread out its branches, and so seize and devour it. At another time it will assume the appearance of being quite withered away, and let itself be tossed to and fro, by the waves, like a piece of sea-weed, until it happens to touch a fish. ”
