taxon notes
Compared to terrestial animals, the cornea of zebrafish is relatively flat. It consists of nonpigmented, stratified squamous nonkeratinizing epithelial cells, attached to a thick basement membrane that is considered to be analogous to the Bowman's membrane in mammals. In fish, and aquatic vertebrates in general, the cornea plays no role in focusing light, since it has virtually the same refractive index as water
