The eyes are very small, and they contain Spiracles behind and above them. The retina of its eye is divided into two areas – one adapted for day vision, the other for low-light and night. Because of the relatively small eyes (eye diameter less than 1% of total length ), it has been assumed that the whale shark depends little on vision compared with other senses such as olfaction . But Great White Sharks do not have a nictating membrane so when they hunt their eyes roll backwards into the socket for protection against any threats. Whale sharks are known as gentle, bespeckled giants that swim in tropical seas and scoop up plankton with their cavernous mouths.
