Which one is the shark’s strongest sense?
Read below 👇
In addition to our senses—sight, hearing, touch, smell, and taste—sharks have two other senses, managed by specialized receptors: electroreceptors (Ampullae of Lorenzini) and pressure change detectors (lateral lines).
The sense of hearing is a shark’s most acute sense and is used from the most significant distance, followed by the sense of smell.
As sharks get closer, they engage sight. In proximity of what is attracting them, sharks might use the lateral line to detect movement, then the ampullae of Lorenzini to detect an electric magnetic field.
Most recent studies have also found pit organs on the back, sides, and lower jaws of some shark species.
Their exact function has not yet been clarified, but sharks can perhaps register mechanical stimuli such as water currents with their pit organs.
Ultimately, one sense does not work independently from another, and all senses constitute a powerful network that sharks constantly use to navigate their world.
Tomorrow’s answer will address senses differently and discuss sharks’ deterrents.

These images are collected during our educational trips to encounter up to seven or eight different species of sharks around the northern Bahamas on a special liveaboard for 10 nights 9 days of navigation and dive, learn and surface with a better understanding and appreciation of sharks.
