Electrogenesis refers to the process by which living organisms generate electrical energy. This phenomenon is particularly notable in certain species of fish, such as electric eels and electric rays, which can produce electric fields for navigation, communication, and hunting. The electrical energy is created through specialized cells called electrocytes, which function similarly to batteries. In addition to aquatic organisms, electrogenesis can also be observed in some bacteria and other microorganisms. These organisms can convert chemical energy into electrical energy through biochemical processes, contributing to various ecological functions. Understanding electrogenesis has implications for fields like bioengineering and renewable energy.
