Predator of the lemming:

long-tailed skkuas

Whuh? wwh, your link was rife with spelling errors, and that made it fun to read. It's always fun to read articles on the Net that have spelling errors!

But the long-tailed skkuas? I must go look for that word: skkua. Could it have been skunk? Or is there a skkua and I just never heard of one!

Anyway, I'm glad you posted the link, if only to learn the whole lemmings-into-the-sea is myth--and provided by Disney!
