Fish Have Sexy Ears
You can tell when a fish has changed sex just by looking at its ears.

he team decided to focus on the fishes’ ear stones, or otoliths, which develop through the deposition of daily layers, providing an age-based history of the individual’s growth. They proposed that the process of sex change may effect otolith growth, resulting in formation of an age-specific sex-change signature.
