The ampullae of Lorenzini detect electrical fields generated by other animals, helping sharks locate prey and navigate in their environment.
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.
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
The pores on a shark's snout, known as ampullae of Lorenzini, are specialized electroreceptors that help sharks detect electrical fields of their prey. This sensory adaptation allows sharks to locate prey hidden in sand or murky waters by detecting their bioelectric fields.
Electrical fields
Ampullae are specialized structures found in various organisms, serving different functions depending on the context. In the context of the inner ear, for example, ampullae are part of the vestibular system and contain sensory cells that detect angular motion and balance. In echinoderms, such as sea stars, ampullae are involved in the water vascular system, helping to control movement and feeding by facilitating the extension of tube feet. Overall, ampullae play crucial roles in sensory perception and locomotion across different species.
Ampullae of Lorenzini
The ampullae of Lorenzini detect electrical fields generated by other animals, helping sharks locate prey and navigate in their environment.
Freshwater fish do not have ampullae of Lorenzini, which are specialized electroreceptive organs primarily found in certain species of cartilaginous fish, such as sharks and rays. These organs allow these marine species to detect electric fields in the water, aiding in navigation and hunting. While some fish, like catfish, possess other forms of electroreception, they do not have the same structure as the ampullae of Lorenzini found in their marine relatives.

As a dilated portion of a canal or duct, it is the semicircular canal of the ear
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.
They connect the radial canal to the ampullae in the water vascular system.
The tiny pores covering a shark's snout are called ampullae of Lorenzini. These specialized sensory organs help sharks detect electric fields and temperature changes in the water, allowing them to locate prey and navigate their environment effectively. The ampullae are filled with a gelatinous substance that enhances their sensitivity to electrical signals.
the lemon shark is a bottom feeder that uses its Ampullae of Lorenzo to pick up the electrical pulses given out by possible prey
