Grew up with those in south Georgia. We used to swim in the river that bordered the ranch on two sides, where these were very prevalent. The gators and moccasins had to be watched for...these, not so much. You could catch them on a line, and if they didn't bite it in half, you could fight them for a long time. They have an exolskeleton, and you cut a hole in it, and dip out the meat with a melon-ball maker, putting it in a deep fryer. Good stuff.
Those are Gar, for those that do not know. I know Florida is home to them as well.
