Chiton eyes maybe be the only light field or plenoptic camera to occur in nature.




Chiton a hard shelled mollusk has hard ceramic eyes on it's back.  These eye's can not focus and produce low resolution images.

In seeing these images, having these low resolution eyes in fixed locations may actually give this creature excellent 3D depth perception and it may have excellent vision possibly far better then most fish.

This is done by combining each smaller image to act as part of a larger image sensor, where focus is achieved computationally.
