Singing for Sex

Gentlemen, if you sing a song, you may get some depending on whether or not she likes your voice. However, be prepared to sing for at least fifteen minutes because this is how long it takes her to decide on whether or not you are the one for her. If she really likes your voice, she will expose her genitals and allow you to have your wicked way. A little tap dancing goes a long way too and she definitely likes it from behind. This lady will finally allow you to have your way when you tap out a “mounting” song that she approves of. Even after you have had your way, she can still reject or accept your sperm…

According to a report in New Scientist, this only applies if you are a pond skater belonging to the species, Gerris gracilicornis. The females have apparently evolved a protective shield that covers their genitalia. When the males are able to woo and sing a happy enough tune for her, she will lift the shield and allow mating to occur.

Since you are not a red-backed water strider in a stationary pool in a mountain stream in Japan or Korea, then your potential female mate will respond very well to fine wine and dinning which is probably the Gerris gracilicornis equivalent of a song and tap dance.

A Most Bizarre Sex Act

Spiders weave a tangled sexual web that leads to stiffer competition for passing on their genes. Scientific American reports on a recent study published in the May 2009 issue Evolution that shows how the genitalia of Nephilid and Golden Orb Weaver spiders evolved from simpler to more complex structures.

Male spiders that had more hooks, ridges and twists on their palps stood a greater chance of passing on their genes then their less complex competitors. When the male copulates with the female, the palp breaks off inside the female so there is a greater chance of his sperm fertilizing the female’s eggs. He is not only content from giving her his all, but will stick around her web and chase off any competitors. Female ducts evolved from those that gave straight easy access to more convoluted ducts with twists and turns making it harder for penetration by males lacking the right equipment.
