electroplaque

biology
Also known as: electrocyte

Quick Summary

An electroplaque is a specialized cell found in certain fish that forms the basic unit of their bioelectric organs. These organs are capable of producing and using electrical power for functions like hunting or self-defense.123

Large numbers of electroplaques are arranged in series and parallel within the electric organ. This arrangement allows the fish to generate significant voltage and current. By timing nerve impulses, the fish can activate all the electroplaques simultaneously, delivering a powerful electric shock. Examples of fish with strong electric organs include the electric eel and the electric ray. Other fish use their bioelectric organs as sensory tools to detect prey.134
