I just watched the season 3 opener of River Monsters, they are saying these fish are in 19 of the United States. I found online that Oklahoma is one of them. Trying to find out where in Oklahoma they have been located.Jeremy Wade, the river monsters guy is claiming that in New Guinea these fish have gone from eating seeds and nuts to mens genitals! I would love to know where they are, although between them and the snakeheads I dont believe Ill have my children or grandchildren in any lakes! Can you please help me find out where they have been found? Thank you so much.
