Moray eels do not see well. How do they know this stuff? My dive buddy was new. He was worried how close I got with my camera. He told me after the dive. The moray are pretty tolerant as long as you do not move fast. So far! I have not been bitten. The open mouth shot lends some danger to the image. The blue wrasse hanging about is doing cleaning service. Morays can be quite large. But usually you don’t get to see them because they are mostly hidden in the coral.
