This week in Fish: Fish eyes through the lens

Among other great images, we have posted photos of the eyes of a Longhead Flathead and a Smalltooth Flounder. The images were not taken with fish eye lenses :). Nearly all species of fishes have eyes, but some don't.  We've provided some links to information on blind fishes plus one link to an Australian species that is blind-in-name-only.
