Fish are known mostly for swimming in water and not jumping out of the water. However, certain fishes tend to jump and some can jump fairly high. Some can even fly. Well not really, but the flying fish can actually soar for quite a distance. Fish tend to jump for several reasons, the most common being because the fish is hunting or is being hunted. Jumping makes for a good defense mechanism as the fish being hunted can temporarily escape the fish that is doing the hunting. Game fish such as marlin and largemouth bass tend to jump out of the water to loosen the hook that may be stuck to their lip. These fish will jump clear out of the water and shake their head violently in an effort to remove the hook that is impeding their freedom. Other fish, such as the invasive Asian carp, have been known to jump out of the water when an outboard powered boat drives through the water in which these fish live. There are plenty of YouTube videos showing these carp jumping out of the water, often landing in the boats that are going through the area. It is not known why these fish jump but there is speculation that the outboard motor's noise causes the fish to jump out of the water.
