Polype

Definition and stakes

Portrait of Herbert Spencer Herbert Spencer,  The Principles of Biology, Volume 1…

“ When, from the process by which food is digested, we turn to the process by which it is seized, the same general truth faces us. The stinging and contractile power of a polype's tentacle, correspond to the sensitiveness and strength of the creatures serving it for prey. Unless that external change which brings one of these creatures in contact with the tentacle, were quickly followed by those internal changes which result in the coiling and drawing up of the tentacle, the polype would die of inanition. ”

Various,  The Cornhill Magazine, February… (1860)

“ Make it a rule to pop every unknown object into your wide-mouthed phial. In the water it will probably at once reveal its nature: if it be a Polype, it will expand its tentacles; if not, you can identify it at leisure on reaching home, by the aid of pictures and descriptions. See, as I drop one of these into the water, it at once assumes the well-known shape of the Polype. And now we will see what these blood-red dabs may be; in spite of their unusual colour, I cannot help suspecting them to be Polypes also. Give me the camel-hair brush. Gently the dab is removed, and transferred to the phial. ”
