How to Dissect a Worm
Caveat: Earthworms have blood too. So be nice to them. If you are fortunate enough to go to a school where the pursuit of scientific knowledge is not being held hostage to PETA (or other ad hoc groups that consider anatomy and physiology politically incorrect,[link widoczny dla zalogowanych], cruel and barbaric,[link widoczny dla zalogowanych], etc.) the earthworm is your best bet for learning about life. Many a surgeon learned on something small and supposedly not cognizant thus the earthworm. You will have to numb the brainstem of the earthworm as well. If the worm has circulation it can feel, so in the pursuit of knowledge, ethics must be present. If it is segmented and you see one or more bands,[link widoczny dla zalogowanych], it is about to reproduce, so you may learn more. If you find that you have rolling, gently take a toothpick and run it along your incision on one side only, because the tiny segments you see on the outside continue to the inside as ribs ( they are really muscles) so the worm tends to be ROUND .
Helpful Observation: If you hate using isopropyl alcohol to anesthetize the worms,[link widoczny dla zalogowanych], wait till it has rained a lot, A drowned worm is easier to work on, but still use a little alcohol to make sure it does not undergo any pain. When you are done, put the earthworm into the earth and it will recycle itself organically.
The worm has mud in it, It is not pus. Be respectful of the fact that this small creature can literally move the earth, and does not need a hardhat and a big diesel shovel to do it. If it was not for earthworms, nothing would grow. There would be no such thing as dirt.
