How do eels shock you?
When an electric eel senses prey, or a threat, it sends a signal through its nervous system to the electrocytes. Nerve fibres join each electrocyte on one of its sides, but not the other. The arrival of a signal causes positively-charged sodium ions (Na+) to flood into the cell.
