I have a couple of questions for you.
1)Are you gonna mount it,take it on the road, show it to someone, etc.?
2)If not, why are you asking?
They can float up in rivers, die of "clear weather lightening", have a heart attack or stroke just like any other critter.
Just some food for thought, now that you've asked an expert internet board, you're exposed.
If, on the other hand you'd simply looked it up on said internet, then you would've known AND no one else would've known what you're up to.
