not really a legendary creature, or mythical, but the Tazmanian Wolf...I think they are still alive, and I would really like to see one
there is one thing that I heard off of the Discovery Channel (they have neet shows like this every so often) about some sort of half-man, half-tazmanian devil creature, about the size of a common german sheppard, but it can walk upright as well as on all 4's...If I could remember what it was, i'd post some pics that people have posted.
Lotsa scary things out there I tells ya...I'm sure some of them exist.
