Male spiders spin what is called a sperm web onto which they ejaculate. They then transfer the sperm into structures on the tips of their pedipalps that are like syringes. He does all this before he ever begins the courtship process. If the female has been receptive to his advances, he will then inject his sperm into her genital opening. Females can lay up to 3,000 eggs! Some females die after laying her eggs, and others live on to care for their babies.
