Alien-like moray eel has double jaws

This week’s Nature has a report by researchers studying the moray eel. Seems they have found that the eels’ have a second set of jaws (ala the alien in the movie Alien) that helps them to hold on to prey. Unlike Alien, the 2nd set of jaws doesn’t pop out of the animal, but it does move forward to grab on to prey and help the eel swallow. Neat!
