Lemon sharks rely primarily on electroreceptivity to hunt prey and navigate but have evolved unique eyes that help them see in the murky coastal waters. Like humans, the eyes of the Lemon Shark contain both rods and cones which help them pick up shapes and colors. They have a special retina that reduces glare and helps them see very light wavelengths in the yellow-green color spectrum.
