Oh, god, that reminds me, tangentially: I was watching a River Monsters episode about the alligator gar, which used to be all over North America - particularly in the South, though - and then started getting blamed for these attacks on people - plus they're "trash fish," because they eat more valuable fish (as we define valuable). So Texas (of course) starts a gar extermination program where they go down rivers like electrocuting gar and everything else, and even now you get people shooting gar, using just barbaric methods to kill them in mass numbers. And now the gar is like, endangered, and the dude on River Monsters concludes at the end that gar aren't even aggressive toward people and it was probably alligators that had attacked those people. Poor alligator gar.
