Clustered in their heads sharks have sense organs called the ampullae of Lorenzini What do they detect?
Electrical signals
What are the nerve receptors in a shark's snout called?
Ampullae of Lorenzini
What is the function of the ampullae of lorenzini?
the ampullae of lorenzini is a sensory organ which allows sharks to "feel" the electromagnetic field of their prey.
How is the ampulle of lorenzini related to electricity?
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)
How do the ampullae of Lorenzini help a shark hunt?
it helps the shark by sending signals to its brain about what it smells
What are the things at the end of a sharks nose?
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.
Can sharks sense electromagnetic fields to help find food underwater?
Yes. Using a system known as 'Ampullae of Lorenzini' they can detect flex of muscles of nearby prey. This system is common to all sharks.
What do the ampullae of lorenzini?
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

Can Sharks detect their prey without seeing or smelling it?
Yes, because they can use the ampullae of lorenzini. It helps the shark detect its preys magnetic feild.
Can you tell me which one is meat eater Is it lateral line Carnivore Ampullae of Lorenzini or Pup?
i think the top in the hunt game are gators,anacondas, tigers, lions, polar bears, grizzlys,and pythons
Define Shark ampulla of Lorenzini?
First of all it is called the Ampullae of Lorenzini. Second of all they are gell filled sacs located on the tip of the sharks nose and near the spiracle of a shark. They transmit electronic sensor waves into the ocean locating nearby prey and large objects around them. They were originally thought of as mechanoreceptors which are mechanical deformations that sent electical waves to the brain. These organs are so sensitive amongst few sharks and rays that they will send five billionths of a volt per centimeter. These sacs are also scattered around the lateral line to check prey and when the shark turns a greater distance is uncovered through the Ampullae of Lorenzini. It was first discovered and documented by Stefano Lorenzini in the seventeenth century. This explorer from Italy documented many sharks taking new levels to the discovery of the whole shrk kingdom and anatomy as well as Eugine Clark. The scientist A.J. Kalmijn, producted many experiments involving the Ampullae. He implied that they came in around the hunting and maturing stages of the sharks growth. What is now known is the Ampullae is also equally responsive to the Earth's Magnetic field. A hypothesis asks if the Ampullae of Lorenzini in rays helps deliver and formulate electric shock. While there is much knowledge of the Ampullae of Lorenzini it just comes to show that there is always more to learn. About me: I am only twelve but I have been researching sharks for five years and absolutley love them. At the library, my main source of information, I enjoy reading college and advanced level shark books and so far my favorite sharks are the Tiger and Brown Banded Bamboo Sharks. I would Google them. They are so cool. Right now I want to become a marine biologist who perfects in the study of Ichthyology. That's all for now!
