Barreleyed Evolution

Some things are just weird.

The little gem to the left here is the Barreleye Fish, Macropinna microstoma. The green spheres are the eyes. The things that look like Sad Sack eyes are in fact nostrils.

The fish has to watch up to find food and look for predators but, as can be seen, the mouth is below where the eyes can look-- or, below where the could look if the head wasn't transparent. There's an abstract for the mechanism of biological transparency here. The ecology and physiology is discussed here.

Transparency has evolved over an array of organisms, mostly pelagic. Worms, medusae and fish and other groups all have transparent representatives. My own feeling is that though the underlying mechanism may be primitive and thereby available to multiple groups, the selection pressure to propagate transparency is likely vastly different between, say, a comb jelly and a fish.
