She's been called "terrifying" and "the stuff of nightmares." She has a luminescent stalk that draws in prey, and she can distend her stomach to eat marine life twice her size. Her chompers look more like fangs than teeth.
And she's only 3.5 inches long.
Marine researchers recently encountered this tiny fish, a type of anglerfish called a black seadevil, nearly 2,000 feet below sea level in a canyon off the coast of California as she lit her way through the dark. It is believed to be the first time she has been captured on film at that depth.
There's no question, by the way, that she is a she. Male anglerfish are much smaller, and, when you get down to it, little more than swimming reproductive organs.
