I'm looking specifically for examples and comparisons, because the definitions of inverted and everted are remarkably similar; e.g. from Dictionary.com/Reference.com:
verb (used with object) to turn outward or inside out.
vs. (esp. #5)
inverted verb (used with object) 1. to turn upside down. 2. to reverse in position, order, direction, or relationship. 3. to turn or change to the opposite or contrary, as in nature, bearing, or effect: to invert a process. 4. to turn inward or back upon itself. 5. to turn inside out.
I'm curious because of this:
Structurally, the cephalopod eye differs from the vertebrate eye. Cephalopods do not have a cornea, and the retina is everted so that the distal end of photoreceptive cells lies directly behind the lens and points toward incoming light. As a result, photoreceptor cells connect to the optic nerve behind the retina (Packard 1972).

If you have the rep please tag this with cephalopod; the tag doesn't exist and I don't have enough rep to create it. Thanks.
