Watch the video the WHOLE way through! It's actually very interesting!
Morays have two sets of jaws. Once the first set bites down on prey the second set comes forward to shear off a chunk of flesh. Beautiful yet disgusting. NEVER get bit by a moray!
The back story is this Divemaster takes groups out to this spot where he regularly feeds the eel. Hyjinx ensue...later some guy went back to that spot and speared the eel for revenge, if I remember correctly...I'm NOT 100% certain. Something eerily similar happened to a famous wolf eel in Northern California so I may be mistaken. We always show this video in dive classes as an example of why wild animals need to stay wild. Take only pictures, leave only bubbles.
