Traumatic insemination, also known as hypodermic insemination, is the mating practice in some species of invertebratesin which the male pierces the female’s abdomen with his penis and injects his sperm through the wound into her abdominal cavity. The sperm diffuse through the female’s hemolymph, reaching the ovaries and resulting in fertilization. The process is detrimental to the female’s health. It creates an open wound which impairs the female until it heals, and is susceptible to infection. The injection of sperm and ejaculatory fluids into the hemocoel can also trigger an immune reaction in the female. (via Shane Vigil)
And some people believe God divinely created this utterly barbaric method of copulation? Or did it evolve?
