I don't have all of them, or prolly even enough to keep this batch alive, but I found a cool kid friendly site with all sorts of information about worms and worm binds

And there is a cool part by part picto-screen-thing, with all sorts of technical words...clitellum
I have high hopes the screens are not that necessary....
