Why do tuna jump out of water?

Can Sharks stay still in the water?
Myth #1: Sharks Must Swim Constantly, or They Die Some sharks must swim constantly in order to keep oxygen-rich water flowing over their gills, but others are able to pass water through their respiratory system by a pumping motion of their pharynx. This allows them to rest on the sea floor and still breathe.
Will a shark die if it swims backwards?
Fact of the day: Unlike fish, sharks cannot stop suddenly or swim backward. A shark’s pectoral fins cannot bend upwards like a fish, limiting its swimming ability to forward motion. If a shark needs to move backward, it uses gravity to fall, not swim backwards.
