Are there sharks in the water when a tsunami hits?

Answer 1

No. (Read the bottom as well)

Sharks have a water filled canal system beneath their skin called the lateral line. Pressure sensitive cells can detect differences in pressure between one point and another. This system allows the shark to sense water movement and acceleration it uses this information to avoid predators and to locate.

Sharks can find nearby objects by detecting changes in the water movements. They can also feel hot, cold and pain. Many sharks living on the seabed have barbels, which are used to probe the sand for food.

Many fishes swim by contracting and relaxing a succession of muscle blocks, called myomeres, alternately on each side of the body, starting at the head and progressing down toward the tail. The alternate shortening and relaxing of successive muscle blocks, which bends part of the body first toward one side and then toward the other, results in a series of waves traveling down the fish's body. The rear part of each wave thrusts against the water and propels the fish forward. This type of movement is quite clearly seen in the freshwater eel. Because movement of the head back and forth exerts drag, which consumes additional energy and slows travel, a great many fishes have modified this snakelike motion by keeping the waves very small along most of the length of the body, in some cases showing no obvious movement at all, and then increasing them sharply in the tail region. It is the end of the traveling waves that moves the tail forcefully back and forth, providing the main propulsion for forward motion. A simpler form of tail propulsion is seen in such inflexible-bodied fishes as the trunkfish, which simply alternates contractions of all the muscle blocks on one side of the body with those on the other side, causing the tail to move from side to side like a sculling paddle.

Because fish move this way, they feel any and all movements in the water. The Shark will feel all the animals moving away, or the unmeasurable amount of movement because of the Tsunami that is about to hit, they will all run away too.

Nothing is perfect in this universe. There are always loopholes and mistakes that PEOPLE fine and do. So why not fish? Of course animals are not all perfect, just like us, so yes. Sometimes some sharks (and fish) will stay as the storm hits and they will wash ashore. Usually, as the water falls back into the sea, the wildlife is dragged back as well.
