Four-day-old zebrafish

Caption

This zebrafish larva has been genetically modified so that the bone-forming cells in the face emit a green fluorescence. Normally, they are colorless and transparent, thus almost invisible at this stage. As embryos, their head and tail start to form after just 16 hours. As adults, they grow to be just 2-5 centimeters long.
