🤔 Guess first

Which one is REALLY true about the Moray Eel?

The short version

Moray eels hunt inside tight reef cracks where there is no room for suction feeding, so they evolved pharyngeal jaws — a second toothed set deep in the throat that launches forward into the mouth, grabs the prey and hauls it back. It was only filmed in 2007 and inspired the creature in Alien.

Why it's so weird

  • The Moray Eel hides a second set of toothed jaws deep in its throat, called pharyngeal jaws.
  • The Moray Eel cannot pull in with suction like most fish, because it hunts inside reef cracks too tight to make suction work.
  • The Moray Eel shoots those inner jaws forward into its mouth, clamps onto the , and drags it back down its throat.
  • The Moray Eel was only caught on film using its hidden throat jaws in 2007, long after scientists suspected they were there.
  • The Moray Eel inspired the creature in the movie Alien, the one that lunges out with a second set of jaws.
