My snapping turtle has never messed with his plastic covered heater. It is level with the small stone substrate and directly under the flow from the filter. The only thing I worried about was him messing with the cable that runs out of the tank from it but he climbed on it for a bit before growing bored.
I had a friend who had a pleco that tried sucking on a cheap heater once and it burned its mouth and died. What a bummer.
