how far can sharks smell blood from

The distance at which sharks can detect blood depends on several factors, including the species of shark, the amount of blood in the water, and the environmental conditions. On average, some species of sharks can detect blood from as far as 1 mile (1.6 kilometers) away, while others may detect it from up to several hundred feet (tens of meters).

The great white shark, one of the most studied species, can detect a small amount of blood in water from about 100 yards (90 meters) away. However, if there is a large amount of blood, the detection range can increase significantly.

It’s important to note that sharks don’t specifically "smell" blood but use their senses to detect the chemical cues in the water. They can detect very low concentrations of certain substances, which helps them locate prey or investigate potential food sources.
