Transparent Fish

This 'weird fish with transparent head' was first discovered in 1939, but has only recently been found alive. The image was taken in 2004 but was just released in February, 2009 and published on the National Geographic website. It was taken by the Monterey Bay Aquarium Research Institute in the deep waters off California's central coast. Its name is barreleye (Macropinna microstoma) and as you can see, its forehead is similar to a cockpit. It is completely transparent enabling you to see its inner workings. What you would think were eyes at the front of its head are actually smell sensors. The eyes are tubes (or barrels - hence barreleye) that lie under the green domes in its head. The domes themselves are used to filter out the small amounts of light that reaches down into the deep, dark waters it calls home.
