Spotting

Maybe the eel is catadromous like the American Eel? Catadromous is the opposite of Anadromous (many salmon species in Alaska are anadromous). The American eel goes out to the ocean to breed, but as adults they spend most of their time in freshwater. Or the eel could be catadromous or neither. Either way that is an awesome finding!

The area leads out to a mangrove swamp and then to the ocean so its probably a brackish area.

This is a very interesting spotting, can not found much information if it was found on fresh water but that makes it even more interesting to me!!

Fresh water or Ocean I can not tell by the picture?

Yes I think it is an eel. It was near the water's edge where we were pulling up our boat.

Is that some type of eel? whatever it is is very intriguing...
