I have a worm question,please.?

I have heard of 10-15ft. long worms (in Australia,I think) and i was wondering:What they were called,where they were found,a good website to find some pictures of them,what all kinds of worms live in America(besides night crawlers and red worms)and maybe some information on the kinds of worms that are in America.I know it's a lot,but any information would be appreciated.Thank you:)!
