The Albrecht Group in the Department of Biology at the University of Fribourg, investigates circadian rhythms in biological systems. Recently Urs Albrecht submitted a photo of baby squid for the Swiss Art + Science Competition sponsored by Promega AG. We have covered squid communication in a separate blog. Here we talk to him about the photo and the inspiration behind it.
How did you become interested in squids as an experimental model?
My lab works mainly with mice. Other professors work with different organisms such as Drosophila, C. elegans, plants, and yeast at our university. One of them, Simon Sprecher, became interested in marine biology and started a course for students. I immediately thought that’s a great idea because it is something different, and few actually look deeply into the biology of marine organisms. The literature on squids is scarce and old, and they are challenging to keep in lab conditions. Yet, my colleague ordered Loligo vulgaris eggs from Villefranche Sur Mer in France and started establishing them to hatch and grow in Fribourg. He was successful. The next step was setting up experimentation. However, squids have brains, and to carry out experiments with them, we needed to apply for authorization from the Swiss Government. I helped out, but it was challenging because there were no standards and regulations, as nobody works on these animals in Switzerland. Now we are interested in studying the communication between squids. It is easy to observe how they change color, because they are transparent. The change in color is related to their stress level and mood.
What went into taking the image “One Out”?
I’ve been a hobby photographer since I am ten years old. So when I went to my colleague’s lab and looked at the baby squids, I said, “Ohh, they are beautiful.” They looked really stunning, and some of them started changing colors in front of me. I thought that was a fascinating behavior, and I wanted to capture that.
Baby squids are transparent and colorful. I had to think about how I could best picture them. I decided to have them in a Petri dish and put them on a stand with lighting coming from below on a black background. I made several images. On one of them, there was this situation where one of the squids was changing color. It was very different from all the others. It immediately came to my mind that something was happening. They were communicating.
