Now this fish, perhaps more than all the others, looks like something you might see on another planet. And not one of those bogus Star Trek planets where things are pretty much the same except for pointy ears. The fish has a head that is made of very transparent scales and eyes that are almost always pointed upward and are protected by green orb-like lenses. Yes, it can look out through the top of its own head. This fish was found off the deep sea of Monterey California and was photographed alive for the first time in 2004. This fish is only six centimeters in diameter and the world has known of its existence since 1939 but it was only seen mangled in the nets of fishermen.
