Correspondingly, can sharks swim upwards?

One may also ask, do sharks swim in a straight line? In white sharks that's typically about 2 to3 miles per hour, but that's not the same as how fast they're actually swimming because their paths are rarely straight lines. Sophisticated tag sensors have shown that mako sharks can swim more than 40 miles per hour for short bursts.
Furthermore, can sharks swim sideways?
Hammerhead sharks roll over and swim sideways to save energy. They're sideways swimmers. Most sharks use their large pectoral fins, on the sides of their bodies rather like aircraft wings, to keep them from sinking. The dorsal fin, on a shark's back, helps with quick turns, like the rudder on a boat.
Do sharks die if they stop swimming?
3. If a shark stops moving, it will die. Most sharks don't have to constantly swim to breathe or to stay alive. But about two dozen species—including the great white, the whale shark, and the mako shark—are known as “obligate ram ventilators,” meaning it is mostly essential for them to keep moving to stay alive.
