This looks to be a confusing mix of traits that are in some respects worse than real sharks and in others simply unfitting. Real sharks can sniff out a drop of blood in a much greater quantity of water. Most of them also live in the open sea, so I don't get why saltwater would dry out her skin more. And since when can sharks digest a more diverse food pallet than humans? As far as I know they're still overall carnivores while humans are omnivores and therefore have the other half of the ecosystem open to feed on. I heard of them eating coins dropped into their tanks in captivity and dieing of it.

The shark smelling a drop of blood in a swimming pool myth was disproved--their sensory range is nowhere near that good, though it is good. No clue about the dry skin business--it makes no sense to me either. Sharks bite things they're curious about, and that includes stuff like license plates and other inedible things, but they can of course choke on things as humans can, so I wouldn't dismiss that coin anecdote without research. Diversity of food consumption could be based on all the things we've found in sharks' stomachs rather than true shark -isms.
