How Do Sharks Know When Something Is Food Or Not?

Answer:

Studies have proved that shark senses are responsible for shark hunting.

They commonly use their electro sense for the location of prey, even at long distances.

The lateral line sense detects water vibrations usual to most living things.

The smell and hearing are also used for confirmation, leaving to the sight the last check if a prey is edible.

After all these sensorial scannings, sharks sometimes test their food if they are not familiar with it.
