What light is invisible to fish?
Polarized light
Polarized light is light that travels in the same plane and that is way light travels through water. By reflecting the polarized light they can appear invisible to a predator and they are most effective when the fish are positioned at an angle similar to the angle at which they are attacked.
Can fish hear you?
