The 5 day cavefish embryo image from the welcome trust imaging competition looks like an adult fish. Tastebuds and the processed in the nervous system have been stained using a green fluorescence antibody. Cavefishes live in a dark environment and can survive without eyes. Development of eyes at this embryonic stage is fascinating,. Howevee eyes gradually degenerate and become redundant throughout their lifetime. Monica Folgueira, who captured the confocal image beleives research on these species could contribute to our understanding of the influence of environment on brain morphology thriugh adaptation and evolution.
