taxon notes
in aves, stromal mesenchymal cells may migrate to the iris and become skeletal, The muscle cells of the iris are smooth muscle in mammals and amphibians, but are striated muscle in birds and reptiles. Many fish have neither, and, as a result, their irides are unable to dilate and contract, so that the pupil always remains of a fixed size[Romer, via WP]
