The Puffer Forum

I've noticed at lfs that some puffers have holographic green and blue eyes, almost like its 3D in a way. I know you've seen them before because friends of mine have said the same thing. Some puffers just have black eyes and then some when the lights hit it right, it's like a blue 3D effect to them.

Can anyone explain why? I'm new to this site so maybe this has been talked about before.

They have different eyes than humans because they need to see in different conditions such as low light.

There have been multiple variations on adapting the eyes to varied light conditions. In fish the most widely seen is the omega eye in sucker-mouth catfish. To me the mot interesting is the bifocal lens and eye structure of the Anableps (a.k.a. the Fpur-eyed Fish).
