The Hotheaded Naked Ice Borer is a fictional animal invented by Discover magazine as an April Fool's Day joke. A short article on the Hotheaded Naked Ice Borer first appeared in the April 1995 issue of Discover magazine. The article was written by Tim Folger, then an editor at the magazine. Folger wrote several other April Fool stories for the magazine, including a basketball-sized particle named the "bigon", and the discovery of prehistoric musical instruments— rhinoceros bladder bagpipes, a mastodon-tusk tuba, and a bone triangle—supposedly used by Neanderthals.
