Senses

The Ampullae of Lorenzini are specialized sensory organs found in sharks and other cartilaginous fish. These jelly-filled pores, located primarily around the shark's snout, allow them to detect minute electric fields generated by the muscle contractions of their prey. This electroreception ability is crucial for hunting, especially in murky waters where visibility is low. By sensing the electrical signals, sharks can locate hidden or buried prey with remarkable precision, giving them an edge as formidable predators in the ocean. When I'm on private dive guide trips here in the Bahamas teaching people how to safely dive with sharks, I often start with telling them not to splash the water even at the surface when they're descending for a free dive to the area where the sharks are because of these sensory organs that the sharks have. They might be attracted to the splashing of the water at the surface, which will make the shark more interested in you even as you're descending, and this can sometimes be dangerous if the shark finds you "too" interesting.
