Clownfish burst onto the public scene nearly a decade ago with DisneyPIXAR's now classic animated film "Finding Nemo." Perhaps unsurprisingly, the film left out a very important part of the clownfish story that clownfish can actually change their sex in response to their social environment. Beckman Institute neuroscientist Justin Rhodes examines how the clownfish brain orchestrates this amazing, genderbending swap.
