Opsins for behavior, not sight
Why do fish possess more than 40 opsins, many expressed outside the eyes? Bruno Fontinha, Theresa Zekoll, Kristin Tessmar-Raible and colleagues reveal that combined loss of two non-visual opsins rescues the effects of their individual losses on behavior and gene expression, implicating tmt-opsin-expressing cells, together with other opsins, in behavioral fine-tuning, dependent on ambient light.
