 Zebrafish habitats tend to have low visual contrast and strong motion compared to terrestrial environments. This suggests that the visual environment of Zebrafish may be more similar to the visual environment of other aquatic animals than previously thought. These findings could help us better understand the visual demands of the aquatic habitat of Zebrafish, which could provide valuable insight into the evolution of vision in vertebrates.
