The strange "ruffles" are called 'iridic granules' (corpora nigra) and
they are used to to shade the eye from bright sunlight. In bright light
these iridic granules can actually interlock to completely cover the
centre of the pupil. This leaves just two holes open on either end of
the pupil, reducing the amount of light that can enter the eye.
These structures are also found in horses, cattle and sheep.

That is truly weird & amazing. Without the text, I would've guessed it was a deep-sea creature!
