if you mean "Do sharks live in the ocean?" Then yes sharks live in the ocean they can only survive in salt water
The only Shark capable of swimming in fresh water is the Bull Shark in fact it raises young in fresh water because the ocean has too many predators.
death and other types of sharks only some though

It is possible to swim through from an ocean to a river then to a lake but generally, No. Bull Sharks are the only sharks that are found in lakes.
Most of the world's water is in the ocean, however, a significant amount is frozen in glaciers and ice caps at the north and south poles. Only 0.3% of the earth's water is found in rivers and lakes. The Pacific Ocean is the biggest ocean in the world.
For a tiger shark to attack, the water does not have to be very deep at all. For an attack to be possible, you would only have to be in water one quarter up your shin for a baby to attack. If it is a larger tiger shark you are worried about, you could be in water as shallow as halfway up your thigh. For a full grown tiger shark, if your legs are underwater, you are vulnerable.
Shark's are rare and of course found in the ocean. I've only caught about 3 or 4 myself. But just look for a gigantic fish with a fin sticking out, there's a chance that it'll be a shark. They sell for 15,000 bells.
~71% of the earth is covered with water, of that ~97% is salt and ~3% is fresh (2% of fresh water is frozen, only about 1% is available)
The only ocean not found in the Southern Hemisphere is the Arctic Ocean.
