Sharks can only see in shades of grey.
Findings from a study by Australian scientists, released in September 2012, show that sharks' eyes have just one type of cone opsin - or light-sensitive proteins found in the photoreceptor cells of the retina - instead of the two or more that are needed to see colour. Cone opsins are used to help animals see in bright light, and to differentiate between colours.

Can sharks pump water over their gills?
Sharks primarily rely on a method called buccal pumping to move water over their gills, which involves actively closing their mouths and expanding their gill chambers to draw in water. Some species can also use ram ventilation, where they swim with their mouths open, allowing water to flow over their gills naturally. While sharks cannot "pump" water in the same way that some other fish do, they have adapted these methods to ensure adequate oxygen intake.
