@mermaid.kayleigh: Some shark species possess an eye protection mechanism called the nictitating membrane! This inner eyelid covers the eye during feeding or in situations where the eye may become vulnerable to damage, like coming into close contact with my camera here. Not all sharks have this feature. For instance, great white sharks roll their eyes back during predation to protect them! @KaimanaOceanSafari 🦈 #savesharks #oceanicwhitetip #sharkdiving #sharkdiver #ocean #hawaii
