E_americanus;1042182; said:"It looked like an alligator. It had a flat, broad head...."
flat broad head can be used for pretty much any gar, except perhaps a longnose.
"and do your research about alligator gars americanus."
i'm not trying to brag, but trust me when i say i have very likely done much more research on gars than you have done
given richard's statement, there is a chance they could have been illegally introduced, but again, vouchered specimens and no data exist showing them in this range.
talk is cheap, buy an underwater camera and snap a photo next time--
