alien dolphin - update

Yeah! How ironic!
Of all tose uploads, this one the one I wanted to upload the most, and it's turn came the last!
well, last but not least, it's here!
There also is something I imagined what the eye anatomy would be like. Nothing fancy, except for the fact that there is a lot of room for eye movement (I still don't know if this is what I wanted ) and two lenses in each eye. The optic nerve creates no black spot, the lenses themselves cannot change shape so the focusing is done by increasing or dicreasing the distance between them. The thing that is still left is comming up with a "material" the very front of the eye would be made of, but I was thinking about a transparent scale which protects the eye at all times.
Some species have a circular eyelid so they can regulate the ammount of light comming into the eye. The more i think about it, the more I feel a cylindrical eyeball should be in a cylindrical orbit and a round eye should be in a spherical orbit, so this is the only thing that might change.
