how far can sharks detect blood

Sharks have an impressive ability to detect blood in the water, but the exact distance varies widely depending on the species and environmental conditions. Here’s a general summary:

• Short-range detection: For most sharks, the detection range for blood is up to 10–20 feet (3–6 meters). Blood in the water can attract their attention within this range, especially if it’s mixed with other stimuli like thrashing or splashing.

• Long-range detection: Some studies suggest that certain shark species, like the great white shark, may detect a single drop of blood in 100 liters of water from as far as 1 mile (1.6 kilometers). However, this is under ideal conditions, such as in clear water and when the blood is mixed with other compounds like fish oils or pheromones.

• Environmental factors: The actual distance can be reduced by water clarity, currents, and the presence of other scents. In murky or turbulent water, detection range is significantly reduced.

It’s important to note that sharks are not mindless predators and attacks on humans are rare. Their ability to detect blood is often exaggerated in popular culture.
