Despite being made of different materials, zebrafishes’ and land animals’ scales form in a similar process.
The scales of fish are made of bones, unlike the keratin-based scales of terrestrial animals. Despite these differences, the same genes direct the development of fishes’ bony scales and those of land animals, researchers reported in a paper published July 17 in eLife.
