I am completing a manuscript for
publication in the scientific literature entitled the Evolution of
Parrotfishes. We have data for 92% of the known species and have an
analysis which shows their genetic relationships. I am seeking your
permission to use the image of Scarus guacamaia at
http://bigelowsociety.com/fish10a/parrot97.htm to illustrate the
complexity of relationships in the tropical Atlantic species. The
closest relative is Scarus coelestinus with a totally different colour
pattern. We are developing an argument as to how this came about. Use
of the image will be fully acknowledged and is for scientific and
educational purposes only.

My reply; I did not take
that picture. It was taken by Paul Humann and published in an earlier
edition of “Reef Fish Identification”. He is very accessible through
the “Reef” organization in Key Largo, FL < outreach@reef.org >; I
think he would like to hear from you.................Rod
