Special eyes

The largescale four-eyed fish has a strange appearance. Although it has 2 eyes and not 4, the eyes are very special. Each eye is divided into an upper part and a lower part. This means that the largescale four-eyed fish can see well in both air and water at the same time.

Specialists

With the upper part of its eye, the largescale four-eyed fish can look above the water's surface at both enemies and prey. Using the lower part of its eye, the fish looks beneath the water – also for both enemies and prey. The largescale four-eyed fish stays level with the water's surface, enabling it to look up and down constantly.
