Electric organs?

Electric organs are specialized organs found in certain fish species, such as electric eels and electric rays, that are capable of generating and discharging electric currents. These organs are used for hunting, communication, and self-defense. The electric organs are made up of specialized cells called electrocytes, which can produce electric impulses through the movement of ions across their membranes. The electric discharge can be used to stun or kill prey, deter predators, or communicate with other members of the species.
