Transsexual Fish is Friendliest in the Sea

The blue groper is a favorite among scuba divers because of its friendly nature. This transsexual fish also has the ability to change gender. To stay protected from other animals, there is usually a certain amount of male gropers in the group, and that gender ratio rarely changes. If a male dies off, the most dominant female takes the role of changing into a male. However, unlike some transsexual animals, once a groper changes from female to male, they can’t go back. This means they can no longer breed or produce eggs.
