Nautilus Eyes (are very cool and should be reflected as such in game)

A nitpick on the texture of the nautilus mob:

My favorite detail about the nautilus as a real-world animal is their unique pinhole eye structure. If you're out of the loop: instead of a typical "camera-type" eye like most animals possess (think humans, dogs, cats, fish, goats, etc.), nautiluses have what's called a "pinhole" eye. Put simply, the eye of a nautilus lacks the general visual appearance you might think of when you think of an eye. Instead, the nautilus just has a small hole leading to an empty space in the side of their head that's just empty. Like seawater is just freely floating around in there. Beams of light simply pass through the small hole in the nautilus' head and hit the light-sensing back wall of their eye hole directly, without first passing through a lens or anything. It's truly a fascinating eye structure. 

Anyway, as it currently stands, the eye for the nautilus uses the same two-pixel design as the mobs with more traditional camera-type eyes, and I would really love to see the nautilus design tweaked to reflect this unique aspect of the nautilus! (Honestly just changing it to a single black pixel the way fish already are in Minecraft would probably be sufficient to represent this feature of the real-world nautilus)

I hope this tweak will allow us to, in even a tiny way, get more eyes on how cool different eye structures in the real-world animal kingdom can be!
