The screaming of a worm is virtual screaming. You would need very acute ears. In any case, even if 2 should have passed on, you now dangle it, or its earthly envelope, in the water before Animal No. 3, the Fish, hoping that the latter is feeling hungry and that you have selected the sort of worm it fancies. Usually 3 will swallow 2. The shock of getting a steel hook snagged in the esophagus is, of course, bad enough, but to be yanked from home into a new and inappropriate environment will probably kill the fish at once.
Death is in any event imminent.
Now you have two small dead animals on your hands. You discard whatever you can find of the worm, leaving one small dead animal to be dealt with. If you do not eat No. 3 on the spot and prefer to keep it until you have a better appetite, you must contrive to keep it as cold as possible. This is necessary because of a whole bunch of really small animals that have been out of the picture up to this point. It is easy to ignore them most of the time since they can be seen only with a microscope.
