Its a Crabby situation

If you were to live in a place with no sunlight would you need eyes? This is a very simple question and most people would say no you do not need eyes but some marine biologist and scientists are starting to think this is not true for some of our fishy friends. Scientists have been looking at some deep sea crab species that live around a half a mile under the water where light can not penetrate and have noticed that some species use their sensitivity to blue and ultraviolet light to sort toxic coral from safe coral. The safe coral is where they may be able to find their food source Plankton. That is a pretty good thing to be able to do if you think about it.
