Sharks have an extremely good sense of smell! They can detect one drop of blood in 25 gallons of water and can smell blood over 1/4 mile away.
Some sharks can detect blood in the water from several miles away. Their keen sense of smell, using special receptors called olfactory organs, allows them to detect tiny amounts of blood and other substances in the water.
