english: All vertebrates do, and each time a fish species starts to adapt to this dark, cold, cave environment, over many, many generations, they lose their eyes and their eyesight until the end up like an eyeless cavefish like this one here.
non_english: Kod svih kičmenjaka je tako, i uvek kad vrsta ribe počne da se adaptira ovoj mračnoj, hladnoj, pećinskoj sredini, tokom mnogih, mnogih generacija, izgube svoje oči i svoj vid dok završe poput bezoke pećinske ribe, poput ove ovde.
