Located just under the skin, the lateral line consists of sensory receptors called neuromasts. When the cilia in the neuromasts vibrate, the fish can feel. The lateral line can also sense and detect water pressure (depth), prey and predators movements, currents, and objects.
Did fish can see air?
This is called refraction index. Air has an extremely low refraction index, making it impossible to see. Neither us nor fish can see the air in the environment.
How do fish see out of water?
It looks like a mirror from underneath when looking at an angle. This effect is caused by sunlight and how much light is reflected back from the bottom in shallower bodies of water.

Can fish see in dark?
Fish living in the deep sea manage to navigate in complete darkness. It’s not strictly ‘seeing’ but fish have rows of pressure-sensitive organs running down each side of their body called the lateral line, which allows them to sense nearby animals from the pressure changes in the water.
