how freaky can a fish get?

Today there's a new addition to the "real life is stranger than fiction" category. Check out the fish Macropinna microstoma. It has tubular eyes and a see-through head.
The common name for the fish is "barreleyes." Monterey Bay Aquarium Research Institute investigators recently figured out why this species has such an unusual head. Its eyes can actually rotate within its "skull," so the transparency allows the wary swimmer to keep a literal eye on happenings above it, as well as to the sides and directly in front.
