could the chupacabra actually be a Thylacine?? It was an animal that looked like a dog, but also had features of a tiger and kangaroo (had a pouch), but had a giant mouth!. (mouth looked normal when closed, but actually opened all the way past the back of the ears!!) It went extinct in 1936... so its believed. Heres a clip of the last known one.... http://video.google.com/videoplay?docid=-1514755351413975110&ei=ZUmiSMLqA4mSrwKx08DTDw&vt=lf&hl=en
