Hello! I am so sorry that I just found a discussion about the purple eggs found in bluecats on Lake Eufaula back in May. I am the researcher that is in the article that you have been referring to. I am a cellular biology major/chemistry minor at a university here in Oklahoma and have lived on this lake for over 35 years. I will try to answer any questions you might have about the phenomenon to the best of my ability (from what we've found so far). I will try to respond as quickly as possible, but please consider how busy I am since I am working on two degrees, have a family, and I am also doing all of the side research on the bluecats. Let me say up front that this phenomenon has never been documented in any reputable biological journals (or unreputable for that matter). This makes this a very challenging thing to research, but at the same time it elevates its importance to find the cause. There has been another article published since the one you are referring to, but I am having trouble accessing the link - if I can get it I will post it. Here is the link to the first article, along with PHOTOS of the reddish purple eggs. http://www.cnhins.com/environment/cnhinsenvironment_story_156015207.html Like I said, feedback or questions are very welcome!
