  • this protein is necessary for normal vision, particularly in low-light conditions
  • as part of the light-sensitive tissue at the back of the eye (the retina), rods provide vision in low light

Starts off with the explanation about how research of the deep sea is the only profession that can provide something new and unknown. Since 95% of the deep ocean remains unexplored, although it is expensive. Also talks about the deep sea organisms such as fish and their  relationship between the bio-luminescence and the visual system as well as raises the question about how the world must look like to deep sea organisms.  The group of 20 scientist on their way from Cape of Good Hope to Durban in Africa discovered that fish deep in the sea actually see in Red, Green, and Blue. Mostly because of the study of the 2 different types of fish the Spookfish and Dragonfish. According to the research they found that a certain type of Dragonfish had a really weird sensitivity to red light, and since most of the fish under the sea could only see blue that meant that they had their own private wavelength (cool fact when you bleed deep underwater you bleed green instead of red). They did this through using chlorophyll in their eyes which can activate other visual pigments allowing them to see. Later they tested on other types of animals such as cows which improved sensitivity to red light. This connected to Rhodopsin because they discovered that it actually be stabalized by chlorophyll. Meaning it could solve a lot of the degradation and unstabilization of Rhodopsin- which is the basis of many retinal diseases. Maybe leading to future treatments for curing blindness in humans.
