Are eels blind?
Electric eels live in muddy waters. Mostly blind, they rely on low-level electrical pulses to navigate and explore their surroundings. Higher levels of voltage are generated to stun or kill prey and to protect them from predators.
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.
