Here are the top ten discoveries of 2009 from the National Geographic. Number 2 is the Pacific barreleye fish viewed alive and caught on video for the first time. It features a transparent soft dome head. Those two green bulbs are the eyes, not the two sleepy things that look like eyes which work more like nostrils. These green lenses are believed to have evolutionarily receded behind this transparent skin in adaptation to the stinging cells of the food source of the barreleye fish.
