Define Shark ampulla of Lorenzini

Answer 1

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!
