I wonder how this poor animal survived without water for that long?

“I wonder how this poor animal survived without water for that long?”

If air could get into the jar it stands to reason that water could as well.

Might it have stuck it head, jar and all, into a lake/river and drank the water that leaked into the jar? No reason to think it didn't, it did have 11 days to figure it out.
