I'm definitely talking snappers (we also have painters, sliders and blanding turtles). The net is large, I've netted 30-pound salmon with it on Lake Michigan. The snappers I've been catching have had a 14-16" carapace. Saw another one this morning. We don't have alligator snappers in Michigan so I can't comment on those monsters.

Another interesting thing is that my bass are about 12-inches and the pond is very clear. When the snappers have come in to feed, the bass are curious and I've seen 4-5 bass swim up to the turtle (nose to nose) but have never seen the snapper try to grab them.
