dolphins can live in both rivers and seas, they are quite common in unpolluted areas but the most likely places to find them are in marine parks and zoos, or in dolphin experiences such as swimming with dolphins :)

A miner would be more likely to use panning to find platinum than to find topaz. This is because platinum is heavier than topaz.
not usually. however i suppose they would if they were hungry enough. Also tiger sharks more than likely would if they could catch them.
I would not say they are not as talented but river dolphins tend to be more shy and not as enthusiastic as sea dolphins. You won't commonly see them jump out of the water and do tricks as you would see other dolphins do.
