Vampire Bat

Vampire Bat, any bat of the genera Desmodus and Diphylla, from Central and South America. The upper canines are very large, and the gullet is too small for anything solid to pass. These bats live entirely on blood, shaving off the skin of the victim, and sucking the blood from the small vessels exposed.

“Every comfort that the saints have in this world is a promise to them of those eternal mercies which the Lord hath provided for them: as every affliction that the wicked have here, is but the beginning of sorrows.”
–Jeremiah Burroughs, The Rare Jewel of Christian Contentment
