ELECTROPHYSIOLOGICAL investigation has shown that the ampullæ of Lorenzini of elasmobranch fishes are sensitive both to slight changes of temperature 1 and also to weak mechanical stimuli 2. But ...

They connect to long, jelly-filled tubes ending in blind sacs called ampullae, which contain sensory cells and nerves connecting to the brain. The cells enable sharks to home in on hidden prey ...

He concentrated in marine biology and can, to this day, describe the ampullae of Lorenzini and tell you on which end of a shark to look for them. Following a disastrous attempt to learn sufficient ...

This sensitivity to sound is crucial for their survival in the ocean. Sharks possess specialized organs called the Ampullae of Lorenzini, which allow them to detect electrical fields produced by ...

Göritz measures the testes, prostate, urethra, and the ampullae, a trumpet-like organ in elephants that stores semen. Images from the ultrasound wand appear on a laptop screen and reveal good news.

When the heavy cruiser USS Indianapolis sank in July 1945, as many as 80 of the sailors’ deaths were blamed on shark attacks as survivors drifted for five days in the “shark-infested waters ...

The device works, the company says, by causing discomfort to sharks, which detect the electric field in short range sensory receptors called the Ampullae of Lorenzini. The technology was developed ...

Today, he is familiar to many hobbyists as the author of the Detector Finds series that helped in the identification of many British metal-detecting finds, ranging from medieval pilgrim ampullae ...
