Enormous monsters scuttle across the screen in the movie "Alien," devouring humans with a second, saliva-dripping set of jaws thrust from the back of their throats. Although the creatures are contrived, a new study shows that moray eels use such a set of jaws to eat.
The discovery shows that morays use the second, hidden set of jaws to drag unsuspecting meals to their doom—a behavior unique among the eels' bony fish relatives, who suck in meals like vacuum cleaners.
