The Fish That Can Switch Gender

But the fascinating fact about the blue groper is that it can switch gender. Little is known about the nature of their sex change. Kt is believed that they also change gender when they reach a certain size and age.
And if a male is removed from the reef, the biggest female will change into a male. It is also believed that if there is imbalance in the number of males and females, a female may turn into a male or the other way around to keep the balance. Aside from being blue, the males have orange lines radiating from their eyes. The females are smaller and are reddish brown.
