Why this fish has teeth all over its body

This beautiful image of a skate fish embryo reveals something truly extraordinary about the scales on its body. As University of Cambridge biologist Andrew Gillis explains, they are, in fact, quite similar to human teeth. They’re even controlled by genes similar to those that control tooth growth in humans. You may never look at fish scales in the same way again.
