Scientists have uncovered the amazing ability of sharks to detect odors in the ocean. These predators, possessing a unique olfactory system, can pick up the odor of their prey at considerable distances. Their nasal cavities are not designed for breathing, but serve to filter seawater, where sensory cells are located that send signals to the brain.

Sharks are able to smell “in stereo,” which helps them pinpoint the direction in which an odor source is located. Studies show that some species, such as the great white shark and tiger shark, have the largest olfactory apparatuses and this indicates a high sensitivity to odors.
