Moray Eels’ Colorful Transformation

Many moray eels remain the gender they were born their whole lives. That is, except for the ribbon morays like you see above. These colorful eels switch from male to female, but unlike the clownfish, all of them do it.
All of them are born as a male, but after a colorful transformation, they become female. The eel starts out as small and black with streaks of yellow. As the eel grows older and bigger, they turn yellow and get the female reproductive organs.
