Electrocytes are specialized cells found in certain fish, such as electric eels and knifefish, that generate electric fields. These cells are modified muscle cells that can produce electric charges when stimulated. The arrangement of electrocytes in stacks allows for the amplification of the electric signal, enabling these fish to communicate, navigate, and defend themselves. When an electrocyte is activated, it changes its membrane potential, creating a flow of ions that generates an electric current. This current can be used for various purposes, including stunning prey or deterring predators. The ability to produce electricity is a fascinating adaptation in the animal kingdom.
