A fish with transparent head exists?

The Macropinna microstoma, commonly known as "spook-fish" or the "barrel-eye"  was first described in 1937. They are 6 inches long and are found in waters as deep as 3330ft (1015m). They have been found in the Pacific ocean, from the Bering Sea to Japan and Baja California, Mexico.  Not much is known on what they eat but, scientists think they eat jellies. 

 It's common names describes it's tubular eyes. You might be shocked by looking at it's transparent head however in the deep, being transparent isn't unusual.  Also having tubular eyes isn't new, either. It is when the Monterey Bay Aquarium Research Institute (MBARI) filmed one that this fish's awesome factor got known.  The fish was first discovered in 1939, but the transparent nature of the fish wasn't known. It had been caught in nets, but when fish dies, it's transparent part is destroyed. It was thought that it could not see in front of itself for it was never captured alive. The Monterey Bay Team sent remotely operated vehicles to the ocean floor to learn about this fish, finding out it's remarkable feature. The Team had managed to capture a live specimen, and for hours observing the fish which was rotating it's eyes. The see through section of the fish allows it to actually see through itself when looking for food at different angles above it. 

Whatever the science, the see through fish is simply a marvel of nature. If it were possible, could you imagine having this fish as your pet?
