Geschlechtspapille

As a genital papilla or genital papillae (Latin papilla "wart"), the sexual opening is indicated in fish

The sexual opening is located just before the anterior fin on a light "elevation" (papilla). The genital papillae are also called urogenital opening, since both sexual products and the urine are emptied of it. The sex papillae can be used to distinguish sex from fish, which are differently shaped and shaped according to the type of fish.

Before the reproductive process, the papillae discolor and change in some species. During the spawning period, the papilla often changes in the female and becomes a kind of tube.
