czech,
Yours looks viscous and doesn't like the dog?
Yes they are fast and it makes a weird noise when they're neck whips out, you can even hear them snap when they are under water.
I pulled this one out of the local park's pond, the kids catch little sun fish off the bridge and the snappers steal them if the kid doesn't reel them in fast enough, I just lured him in close to the bridge and grabbed him/her by the tail, you can see he didn't want to give up his fish dinner. I pulled an even bigger one than this but didn't have a camera, I could hardly lift him out of the water.
Does anyone know if you can eat these things?
JB,
