The shark week had a show about Bull sharks and how they live in freshwater, "I THINK" they said somehow Bulls can self adjust the salinity in their body. I dont know how to describe it bit if they are in fresh water the shark somehow keeps high salt lavels in their body where the need it or in their skin or somthing, and "I THINK" they can be born in freshwater and live their entire life in freshwater.
If anybody wants I will re-watch the show and listen to how they do it and tell you guys. Let me know if anybody cares before it gets deleted from my tv memory.
And I would not be suprised if some IDIOT wanted a freshwater banded cat and converted it, to say oh look what I did. Like sombody said that pups can live in lower salt levels for a while so its cruel I think also, and I think will slowely die.
I do have a good question for somebody shark smart, because sharks can conduct electricty because saltwater is a strong conductent or whatever in freshwater will the shark loose most of its 6th sence like conducting prey????
