The image is of a rare, unique organism that is relatively unknown, yet holds obvious natural beauty. Exceptional image quality, lighting, and dynamic contrast.
Question. How are you claiming that this is a public domain image? It looks like you just took the image from a website, edited it, and then claimed it was public domain. You're going to have to present some kind of evidence that the person who shot this photo has renounced their copyright over it, otherwise it cannot be used on Wikipedia.

What evidence is that that the owner of the website doesn't assert copyright over it's content? While there's no copyright statement, there certainly isn't anything which states that the images are PD either, and the fact that it's a website created to advertise a book which has been commercially published by the University of Chicago Press strongly indicates that the site's owner doesn't regard the images as PD.
