Sharks have all the senses we have (smell, taste, touch, eyesight, and hearing). They can also sense electricity and vibrations in the water. A shark's primary sense is a keen sense of smell. It can detect one drop of blood in a million drops of water (25 gallons or 100 liters) and can smell blood 0.25 mile (0.4 km) away.
Rubbing blood over skin results in a similar metallic smell based on the same scent molecules. Blood also contains iron atoms. Says Glindemann, âThat humans can âsmellâ iron can be interpreted as a sense for the smell of blood. Early humans were thus probably able to track down wounded prey or tribe members.â.
