"I saw something out of the corner of my eye, and immediately grabbed my camera," Edwards recalled of when he took the picture last November. "I happened to get a good picture of one of them."
Edwards said he does not believe the monster resembles the three-humped creature often depicted in the media.
"In my opinion, it probably looks kind of like a manatee, but not a mammal," Edwards said. "When people see three humps, they're probably just seeing three separate monsters."
The sailor said he doesn't believe legends of there being only one of the creatures.
"It was first seen in 565 A.D.," Edwards said. "Nothing can live that long. It's more likely that there are a number of monsters, offspring of the original."
