True monogamy.

Until recently, monogamy has been regarded as something obvious, a loyal marriage as a sacred thing and marital love as brining one to tears. But biochemists have ruined all of this by sticking their noses into matters of intimacy. Suddenly it appears that true monogamy does not exist, that having a 'bit on the side' is not only biologically useful and evolutionarily necessary, but also more effective in terms of the bearing of offspring compared with ordinary marital relations. It turns out that some 20 to 30 percent of little darlings conceived within marriages, are actually of the extramarital type. As this is the nature of human beings, it corresponds equally to men and women. What more can one say, we all like to have a 'bit on the side', and there's not much that one can do about it. True monogamy is a rarity not only with humans, but also in the animal kingdom. 

To find further examples of monogamy, one must search painstakingly, in the depths of the systematic of animals. An upstanding monogamist is the diplozoon (Diplozoon paradoxum), belonging to the class of flat worms, a parasite on the gills of carps. A professional biological description reads as follows:

The larvae of this parasite, known as dipopra "are characterized by the suckers that they posses on the ventral part of their body and the small nipple on their backs. The fully developed larvae pair up in the following way : the sucker of one larvae attaches to the nipple of another. After a while, this connection becomes permanent, the sexual orifice surrounded by the sucker grows onto the nipple, which contains the sexual orifice of the other larvae. The permanent connection of the sexual orifices ensures lifelong cross fertilisation. The young larvae can only further develop once it is connected with another one." 

This can be seen in the attached illustration. It is best not to look at a colour photo of this specimen as it can put one off monogamy for life.
