Can someone educate me on the difference between the worms on this page?

European vs other nightcrawlers

and..

Wax, vs meal, vs butter, vs spike worms ?????

Thanks!

Speedyworm webpage



EDIT:---------------------
Actually, the links under each item tells a lot about what the worms are and how to store/care for them. My question was more how you would choose one or the other to use as a fishing bait since the webpage says all the baits are the best for all the same fish smile
