Another Freaky Fish with Weird Eyes…

This time is is the barreleye fish (which I heard about listening to the most recent episode of the Geologic Podcast).  The barreleye fish live deep in the Pacicif and, until recently, were only known through dead, mangled fish caught in nets.  Finally, researchers at the Monteray Bay Aquarium Research Institute (MBARI) got a live one to study .  Let’s take a look at the fish in question.

macropinnaThis strange fish has a transparent skull!  Those two things in the front that you think would be eyes are used to detect smells.  Those two green spherelike objects under the transparent skull are the eyes.  The eyes can rotate to look upward, forward or any direction where the skull is transparent.

I am just loving the unique adaptations that fish use to survive and see at depths where little to no light exists!
