Transparent Head! (Video included)

The barreleye (Macropinna microstoma) has extremely light-sensitive eyes that can rotate within a transparent, fluid-filled shield on its head. The fish's tubular eyes are capped by bright green lenses. The eyes point upward (as shown here) when the fish is looking for food overhead. They point forward when the fish is feeding. The two spots above the fish's mouth are olfactory organs called nares, which are analogous to human nostrils. Image: © 2004 MBARI

Stumble upon this in the news, it's a fish with a transparent head, you can actually see how it's eyes move inside, the eyes can move upwards and front, though the vision seems to only be a tunnel like vision.

It's called The barreleye (Macropinna microstoma), living in the depths of the sea where the sun don't shine, it's wondrous how pitch black environment can do to living things.

In this image, you can see that, although the barreleye is facing downward, its eyes are still looking straight up. This close-up "frame grab" from video shows a barreleye that is about 140 mm (six inches) long. Image: © 2004 MBARI

I have lots of interest in strange and mysterious things like space, and when it seems space is a fasinatin' place to explore, there's still a lot we haven't seen on earth, there's probably still depths in the sea that's impossible for us to go, everythin' down that deep will be alien in my eyes, if people tell me this fish was found on another planet, I would reacted the same way now, amazed.

I wonder if there's any civilization down there like that movie The Abyss ;x
