These stats are wrong. A saltwalter crocodile weighs much more than a polar bear. A saltwater croc takes horses buffaloes and cattle, all heavy very easily from land into water. Also, in Australia, croc were hunted until the 0s then they were protected and still are. They haven't stopped growing yet and will take decades to return to full size. At the moment they can weight an imperial ton 2,240 imperial Ibs. They are extremely quick and agile and use their tail as a weapon and their mouth too. A big male polar bear weighs 1500 imperial Ibs. A crocodile would drag it into the water easily. This is an animal that drags 2000ibs wild buffalo into the water It has leather like armour, and I really don't fancy a Polar bear's chances https://images7.memedroid.com/images/UPLOADED170/54f8548873a8c.jpeg
