Blue Ribbon Eel

All blue ribbon eels undergo an immense transformation within their lifetime. At birth, they begin life as males and as they mature they make the switch and become females. Although seemingly remarkable, in the fish world, this occurs more than you might think. Many fish species undergo a sex transformation in their lifetime and can be protogynous hermaphrodites, meaning they begin life as females and then switch males, protandrous hermaphrodites, switching from male to female, or bi-directional hermaphroditism, flip-flopping from one sex to the other several times!
