Research on the color vision of deep-sea fish featured on the cover of Science

Six scientists connected to CEES co-authored the research article, and the publication is now attracting world-wide attention

The scientific publication was published 10 May 2019 in Science, and referenced on the cover.

Researchers at CEES at UiO, along with colleagues in Switzerland and Australia, among other countries, shine a light on the vision of 101 fish species, using genomes as a starting point. Most of the species had only one light-sensitive protein in their rods – just like vertebrates. However, 13 of the deep-sea fish had several genes and corresponding light-sensitive proteins in addition, a fact that was previously unknown. Since the rod opsin light-sensitive proteins adsorb light at a number of different wavelengths the authors propose that deep sea fishes see a kind of different colors in the dark. 

Six researchers connected to CEES are behind the discovery: postdocs Michael Matschiner, Martin Malmstrøm and Ole K. Tørresen, researcher Sissel Jentoft, professor Kjetill S. Jakobsen, and professor II Walter Salzburger.
