The hagfish or "slime hag" is an ancient, jawless vertebrate found throughout the world's oceans, famous for its ability to almost instantly produce vast quantities of mucus, the unique molecular properties of which make it one of nature's stickiest slimes! It is the only vertebrate capable of tying itself in a knot, a skill it uses to twist chunks of meat off large corpses, its preferred food. It is also the only fish capable of sneezing, doing so to clear slime from its single large, round nostril. Its degenerate eyes are covered over by skin, though some species have a primitive third eye scarcely visible atop their head. Learn more weird nature at bogleech.com!
