Electrical fields
Ampullae of Lorenzini
The ampullae of Lorenzini are specialized electroreceptor organs found in cartilaginous fish such as sharks and rays. They function to detect weak electric fields produced by other organisms, helping these predators locate their prey even in dark or murky waters.
The ampullae of Lorenzini detect electrical fields generated by other animals, helping sharks locate prey and navigate in their environment.
it helps the shark by sending signals to its brain about what it smells
I belive your question refers to the «ampullae of Lorenzini».These ampullae of Lorenzini are sharks electroreceptor organs, and they are very efficient to detect and find prey, as well as a «biologic GPS device» sharks use for orientation, using the Earth magnetic fied.
Okay now, the ampullae of Lorenzini sensing organs located generally on the nose/snout of ocean dwellers. Most commonly found on Sharks, rays and some sturgen and reedfish.They were described by Stefano Lorenzini in 1678. You would be able to identify The ampullae of Lorenzini as little pores or holes located around the nose, snout, or mouth of the sharks, ray, or stugen.The purpose of the ampullae of Lorenzini is to sense either the weak bioelectric fields emanating from other animals, or to actively send out electric fields to locate other animals. (This would be similar to bats using sound waves--sonar--to locate food and navigate its world)
The ampullae of Lorenzini are special sensing organs called electroreceptors, forming a network of jelly-filled canals. They are mostly discussed as being found in cartilaginous fishes (sharks, rays, and chimaeras); however, they are also reported to be found in Chondrostei such as Reedfish[1] and sturgeon.[2] Lungfish have also been reported to have them.[1] Teleosts have re-evolved a different type of electroreceptors.[2] They were first described by Stefano Lorenzini in 1678

Yes, because they can use the ampullae of lorenzini. It helps the shark detect its preys magnetic feild.
they are called: Ampullae of Lorenzini. These clusters of sensors are connected to small jelly like tubes through pores on the skin. Jeff Shaw Oceanic Defense http://www.facebook.com/OceanicDefense
