I always thought moray eels were creepy...

...Now I know they are even creepier.

Fact for the day
I read yesterday in the November, 2007 Smithsonian magazine about it being recently discovered that they have a second set of jaws reminiscent of Giger's Alien (eep! the horror...). Other fish use the suction created when they open their mouth to suck in prey. Moray eels can't do this since they live in confined spaces which won't allow them to open their mouths so wide. When they bite onto prey the second set comes up from the throat into the mouth. It grabs onto the prey helping to guide it down the esophagus. Other species of fish also have a second set of jaws known as pharyngeal jaws, but none have this remarkable, startling degree of mobility and deftness.

Read more about it here at National Geographic, and see pictures!
