Do you know angelfish? They are one of the most brightly colored fishes in the sea, and people like to keep them as pets because of their elaborate patterns on their bodies. But perhaps the most interesting thing about angelfish is that there is a kind of angelfish, Bellus Angelfish, which can change from female to male!
你知道神仙鱼吗?它们是海洋中颜色最鲜艳的鱼之一,人们喜欢把它们当宠物养,因为它们身上有精致的图案。但是,可能关于神仙鱼最有趣的事情就是,存在一种名为土耳其仙的神仙鱼,这种鱼可以从雌性变成雄性!
The change happens for a specific reason. Bellus Angelfish live in groups, and each group has one blue male fish and a number of yellow female fish. The male fish is the strongest and largest member of the group. He protects and looks after the females. When the male angelfish dies, the group needs a new protector. This is when the largest female angelfish in the group begins to change her appearance. She begins to grow bigger and, after a week, starts to change color-from yellow to blue. Her behavior changes accordingly and becomes more male-like. Finally, about two weeks later, she becomes completely male!
这种变化是有特定原因的。神仙鱼成群生活,每个群体中会有一条蓝色的雄性鱼和许多黄色的雌性鱼。雄鱼是群体中最强壮和最大的成员。他保护并照顾雌性。当雄性神仙鱼死了,这个群体需要一个新的保护者。这时,群体中最大的雌性雄性鱼开始改变外观。她开始变大,一周后,开始从黄色变为蓝色。她的行为也随之改变,变得更像雄性。最后,大约两周后,她变成了完全的雄性!
