昨天在水族馆，有Haremfish，为了传宗接代，鱼们是常变性的。还有Clownfish。
Clownfish, wrasses, moray eels, gobies and other fish species are known to change sex, including reproductive functions. A school of clownfish is always built into a hierarchy with a female fish at the top. When she dies, the most dominant male changes sex and takes her place.
从前古代有马身人面的神等等。一个女人若有女性身体，却有男子的刚烈，或者反过来，他们就该称自己为x。这是多么迷人的时代啊。
