I would say that the most preferred way is to consult the easily available databases and sources on all things concerned with sharks. After only a short time studying this material, you will come to the realization that sharks have long been established as an ocean-going (salt water) species, and they do not exist in fresh water.
they do not live in fresh water.but they dont need to swim to breath.
Electric eels lives if freshwater rivers. Sharks almost all live in the open ocean. They just wouldn't meet. So no, Sharks don't eat Electric eels.
They live in freshwater.
Sharks are filter feeders and sieve tiny bits of plankton and small animals from the water through the gills as they swim with wide-open mouths. They do not drink water. The blood and tissues of sharks are salty containing high levels of urea, and other salts. Sharks basically are saltier than the sea. Sharks absorb pure water from the sea by Osmosis (through their gills). It's a process where water flows across a semi permeable membrane from an area of higher concentration of water to an area of lower concentration to equalize concentration levels. Sharks can secrete extra salts through their rectal gland. Most sharks can't live in fresh water with the exception of bull sharks which can lower their salt level to enter into fresh water.
I Didnt think there were (though I knew it was possible since bull sharks are the only sharks that can live in freshwater), but recently someone told me their husband had seen some. I believe her and I also believe we are in no immediate danger so long as we know what to do if we encounter one.
no there are also freshwater sharks
No. They are freshwater fish only.
There are some sharks that can live in freshwater environments, but there aren't a lot that can cross over and live in both. The Bull shark is one that has been shown to have the ability to live in both saltwater and freshwater. Interestingly, they have to produce 20 times more urine when living in freshwater. (See the related link for more about Bull Sharks' freshwater tolerance.)
Most all sharks live in saltwater except the bull shark which can live in freshwater and saltwater.
No the salmon and bull and sometimes the blue shark swim in freshwater sometimes.
Plants such as water lilys. I am currently trying to find other plants that live in freshwater but am having trouble.
Not all sharks live in one type of water. Most of them live in saltwater but the bull shark can live in both saltwater and freshwater.
no because they lives in freshwater or saltwater
They can live in both freshwater and salt water but only certain kinds. They only live in waterways with access to the ocean.

Not for long.Only the bull shark has evolved to live in fresh or saltwater.
Yes, they can swim into freshwater rivers.
