Sharks can sense the electric field perturbation?

Click For Summary
SUMMARY

Sharks possess a specialized organ called the ampullae of Lorenzini, enabling them to detect electric fields as weak as 5 x 10^-9 V/m. This remarkable sensitivity allows sharks to perceive environmental changes, including potential vacuum perturbations. The exact methodology for determining this sensitivity is not clearly documented, but it is widely referenced across various scientific sources.

PREREQUISITES
  • Understanding of the ampullae of Lorenzini and its function in sharks
  • Basic knowledge of electric field measurements
  • Familiarity with the concept of vacuum perturbation
  • Awareness of marine biology principles
NEXT STEPS
  • Research the anatomy and function of the ampullae of Lorenzini in detail
  • Explore methods for measuring electric fields in aquatic environments
  • Investigate the implications of vacuum perturbation in biological systems
  • Study the evolutionary advantages of electroreception in marine species
USEFUL FOR

Marine biologists, ecologists, and anyone interested in the sensory adaptations of sharks and their implications for understanding marine life.

Sharks use an organ known has the ampullae of Lorenzini to sense electric fields, they can sense fields as weak as 5*10^-9 V/m.
Which got me thinking, they should in principle be able to detect vacuum perturbation in the field, interesting?

How did they found out such value?
 
Not sure, but that's what I read on a bunch of websites.
I would assume they had a source at a long distance away?
