25 Types of Fish with Big Eyes and Pictures

There are currently close to 35,000 different kinds of fish, making them an extraordinarily diverse collection of animals! Not unexpectedly, each species differs from the others in a wide range of traits and characteristics. Eye size is one of these characteristics.

Like goggles integrated right into their bodies, fish’s unique eyes allow them to see clearly underwater thanks to a protective layer. All other things being equal, fish eyes and human eyes are similar, and fish can distinguish between different colors and tints. A common adaptation for fish living in the deep water, where light is scarce or nonexistent, is for their eyes to be larger than others.
