One of the coolest things I've seen at the zoo ever was the snake we saw on thursday.
There was a (presumably) indigenous snake who found his way into the hen house, and decided to help himself to some delicious fresh eggs. Whole. Of course, I've seen nature shows where the snake swallows things like eggs or other food larger than himself, but I've never seen it live.
After he finished swallowing, he just curled up there where he was. I'm guessing he had some recovery to do after that meal.
