I'm not sure that's wood. Looks sort of like a parsnip or some other root vegetable that would much easier to bite through than actual lumber. I'm sure that thing gives a mean bite no matter what, though...

I agree Wazant,
It almost looks like a large Turnip which could also be the food source.

snapping turtles bite morning wood

Looks like a daikon to me...

yeah the desc. on myspace video said wood. maybe it's shaped like that, it sure does make a plunk when it drops into the water! i was sceptical of the actual material as well.

Most probably a daikon, I hope those are not hot like a regular radish because that turtle is going to get pissed.
