Shantaks are gargantuan aerial organisms which reside in the Cold Waste of Earth's Dreamlands.
They are larger than elephants and have a head reminiscent of that of a horse. They are scaly with slimy skin and are carried through the air by bat-like wings. Their feet form two strong talons.
- The Dream-Quest of Unknown Kadath, by H. P. Lovecraft (1943)
