Scientists discovered that the Brazilian cave insect have their male and female sex organs are reversed. The males have vaginas and the females, big ol’ penises (for an insect). The male still produces the sperm though, the female just dips her penis-like straw (called a gynosome) into his vagina to collect the little swimmers.
During mating, the female’s spiny penis gets tightly anchored to the male vagina’s sperm duct, allowing the female to receive the semen. In other words, this penis functions more like a straw than a spout. If the male tried to break away [during copulation, which lasts between 40-70 hours], his abdomen would rip open, and he would dramatically lose his genitals. These female insects also mate with multiple males and can store two batches of sperm in the body.
Ehm… Amazing.
