Is the jersey devil real?

There is only one devil and his many demons which the Bible states at Revelation 12:9-12 " So down the great dragon was hurled, the original serpent,the one called Devil and Satan, who is misleading the entire inhabited earth; and his angles were hurled down to the earth and his angles were hurled down with him.  On this account be glade,you havens and you who reside in them!  Woe for the earth and sea,because the Devil has come down to you, having great anger,knowing that he has a short period of time."  Knowing the truth about him helps us to see why the world is so bad today.
