       Did you see a person or an animal that changes from female to male before? No, I donot mean in the movies. A fish called the blackspot angelfish can really do so.
       The angelfish live in groups, and each group has one male fish and four female fish.The male is different from the females in color. And he is the strongest and the largestmember of the group. He protects the females and acts like their “security guard”. Whenthe male dies, the group needs a new “security guard”. This is when the largest female fishin the group begins to change its appearance. She begins to grow larger. After a week, shestarts changing color, from yellow to blue. Slowly, she begins to act like a male. Twoweeks later, black stripes appear on her body. This shows that the gender change isfinished. She is now a male fish and the new leader of the group!
