Yapped about my fish and won first prize! Had a wonderful time at #egg2025 last week @britishecologicalsociety.org

In crater Lake Masoko one fish species is splitting into shallow and deep-living ecotypes occupying different light environments. New research shows their visual systems are diverging, and how colours of male eggspots have changed to maximise their visibility. doi.org/10.1093/molb...
