Pharyngeal Jaws of Moray Eels
- Evolved from modified gill arches and associated muscles & ligaments
- Function is to rake prey into esophagus, reposition prey, immobilize prey, crush or disarticulate prey.
- Both upper & lower jaws bear teeth depending on prey type
- Muscles connect the moray’s upper pharyngeal jaws to the skull just behind the eyes, and also run from the lower pharyngeal jaws to the point of the eel’s chin. When the eel contracts those muscles, the throat jaws open and slide forward, almost out of the mouth of the eel. The pharyngeal jaws then close on the part of the prey that is most deeply in the mouth and drag it back towards the stomach. The eels seem to use their secondary jaws about 90 percent of the time.

And we think shit like Aliens (the movie) is a stretch of imagination. A lot of the shit we make up for movies already exists.
