There are several\ntheories related to the possible roles of eyelids in fishes. It is generally\naccepted that the eyelids may play a role in affecting the vision and enhance\nthe ability of fish to focus on specific objects. This is supported by the\npresence of eyelids in deep sea fish whereas better vision and focusing would\nbe of top importance for the survival and well-being of fish in the deeper part\nof ocean as the visibility is severely reduced. It is also believed that eye\nlids serve as a physical barrier and protect fish eyes against foreign objects\nin the waters.<\/p>\n\n\n\n

It is questionable whether the adipose\neyelid could block out ultraviolet light\nand so prevent the UV damage to the fish\u2019s retina in some species.\n\nApart from above, the eyelids served as a\ntaxonomy tool in some fish groups such as mullets. In flathead grey mullet, Mugil cephalus<\/em>, the adipose eyelid is\nwell developed, covering most of pupil with only a narrow slit over the pupil,\nwhile in thin-lip grey mullet (Chelon ramada<\/em>), the adipose eyelid is\npoorly developed.\n\n\n\n<\/p>\n","protected":false},"excerpt":{"rendered":"
