Summery of the Eyes of the depths.

To scientists the deep sea is like Wonderland to Alice. The only way to understand the deep sea, many scientists think is to look through the eyes of a creature that lives there.Creatures that live in the deep sea have a bluish glow.(bioluminescenc.) Scientists recently made a expedition to the Bahamas to see how the animals see that far down.The oceans are thousands of feet deep in some spots.They have to make the submarine silent or else it might scare away the animals there.Bioluminescent creatures make there own light by using chemicals.Its hard to know what it really is because scientists can't spend much time down there.Scientists know that most of the creatures can only see blue light.Scientists have learned a lot about what the animals see and dont see.They want to know what bioluminescense is used for,how often they use it,and what still needs to be discovered. http://www.sciencenewsforkids.com/articles/20071212/Feature1.asp
