Phaedimus
The sponge is governed by a certain little creature more like a spider than a crab. For the sponge wants neither soul nor sense nor blood; but growing to the stones, as many other things do, it has a peculiar motion from itself and to itself, which nevertheless stands in need as it were of a monitor or instructor. For being otherwise of a substance loose and open, and full of holes and hollowness, by reason of the sloth and stupidity of it the sponge-watcher assists to give notice when any thing of food enters the cavities of it, at which time the sponge contracts itself and falls to feeding.
But if a man approach and touch it, being nipped and admonished by the sponge-watcher, it seems to shudder and shut up the body of it, closing and condensing it in such a manner as makes it no easy thing to cut it from the place where it grows.
The purple shellfish also, called porphyrae, clustering together in a kind of mutual society, build up little combs for themselves like bees, wherein they are said to generate; and culling out the choicest substance of the moss and seaweed that stick to their shells, they seem to be in a circular commons among themselves, feeding the one upon the other’s nourishment.
