I believe it's a worthy topic. So maybe the saline environment is the preferable environment? Is it arguable within reason that the beaver will be impeded by the increased buoyancy in saline water? If so, is it sufficient in degree to skew the outcome?
I for one have become a studious disciple of all things pertaining to the mighty beaver. I've become acquainted with their inherent smell, the taste, what they sound like... and believe me, all that research doesn't come cheap. I'd be rich if I had all the money I've ever spent on diapers as a consequence!
No coincidence. Beavers are hardcore and masters of the long game. They possess unparalleled resolve and will stop at nothing. What behavioral scientists fail to understand about beavers at their own peril, is that beavers only attack trees as a matter of practice. They continually hone their skills in preparation for the takeover of the top of the food chain. Sharks should consider themselves lucky that they are protected from beavers by their inability to inhabit non-saline water.
