Can a crocodile see well under water? Can the croc bite underwater? Can it survive the ocean's salt for long?

These 'animal face-off' animations are not to be taken as being an accurate representation of the outcome of a fight between two animals. Although some degree of each animal's advantages and attributes are considered during the construction, it is purely conjecture. Also there is no way to know for sure if each construction is objective or subjective to any degree whatsoever. Furthermore (this being the case with shark v crocodile) such contests obviously must be shown in a viable scenario that each contestant can participate in. This requirement alone may potentially reduce the overall effectiveness and ability that that animal may otherwise have been able to demonstrate. Clearly this contest had to be set in water for obvious reasons ! That said Saltwater crocodiles do actually venture out in to open sea, so in this particular example the scenario is not adopted. (albeit it is highly unlikely that these two animals would EVER meet). Salties (as they are known in their native Australia) are very formidable and hugely powerful animals in or out of water. Their eyesight is excellent in or out of water, better than most sharks and much better than a Great white's. There is a minority of animals in or out of water that could defeat a Saltie and yes they certainly can bite, defend and conduct attacks themselves. In this contest however (I have not seen the animal face-off version) I think an adult female Great White (larger of the 2 es) would be too much for a Saltie. The shark's body shape and girth would make it very difficult for the croc to get any purchase with its jaws. Big and immensely powerful as a Saltie clearly is, a Great White is physically bigger, heavier and certainly even more powerful. Also the shark is a lot more agile and manoeuvrable in water and has stronger jaws than the croc, I would say the shark wins (Great White adult female that is).
