Discovery Channel reports:
Moray eels have two sets of fanged jaws, one to grab with and one launched from their throats to grasp their squirming victims.
The find, outlined in this week's Nature, is the first described case of a vertebrate using a second set of jaws to restrain and move prey. . . .
"The second set of jaws in a moray eel reaches up from within the throat cavity into the oral jaws and grabs the prey," lead author Rita Mehta told Discovery News.
"Once the prey has been grabbed, the jaws move the prey into the esophagus," added Mehta, a biologist at the University of California at Davis.
