Definition:The elastic, clear, membrane-like structure, that is outer most layer of the lens.
Comment:[homology-note] "(...) we reach the inescapable conclusion that the last common ancestor of jawless and jawed vertebrates already possessed an eye that was comparable to that of extant lampreys and gnathostomes. Accordingly, a vertebrate camera-like eye must have been present by the time that lampreys and gnathostomes diverged, around 500 Mya (reference 1); Although the eye varies greatly in adaptative details among vertebrates, its basic structure is the same in all. The human eye is representative of the design typical for a tetrapod. (...) A watery aqueous humor fills the spaces in the eye in front of the lens (...)
