Sharks are masters at detecting molecules and vibrations in the water. They can use their olfactory system (smell) to detect 1 part/ billion of blood in the water and they use their lateral line system to detect minor changes in pressure waves or sound waves in the water. This enables them to detect a specimen in distress.
