The Asian sheepshead wrasse, also known as kobudai in Japan, is a hermaphroditic species, meaning that it has both male and female organs which allows it to change its sex. The species gained media attention when the transformation was caught on camera by the BBC Earth crew while filming in the waters near Sado Island, Japan
