Underwater vision is the ability to see objects underwater, ... The view paths refract (bend) in a manner similar to viewing fish kept in an aquarium.
Most fish species have color vision. There are some species that are capable of seeing ultraviolet while some are sensitive to polarized light. [9] The fish retina has rod cells that provide high visual sensitivity in low light conditions and cone cells that provide higher temporal and spatial resolution than the rod cells are capable of.
Underwater hearing is by bone conduction, and localization of sound appears to depend on differences in amplitude detected by bone conduction. [7] As such, aquatic animals such as fish have a more specialized hearing apparatus that is effective underwater. [8] Fish can sense sound through their lateral lines and their otoliths (ears).

Mesopelagic fish are adapted for an active life under low light conditions. Most of them are visual predators with large eyes. Some of the deeper water fish have tubular eyes with big lenses and only rod cells that look upwards. These give binocular vision and great sensitivity to small light signals. [15]
