Each penis receives sperm only from its corresponding testicle, an adaptation that allows males to mate again if they come across a second female within a short period of time they'll mate with one female using one of their penises, and then the other female with their second penis. Furthermore, females can also produce offspring that can feature genetic material from multiple males in a single clutch if she mated with more than one male. In such circumstances, molecular testing techniques can be used to identify whether her offspring share all or some of their genetic make-up with their mother. Like snakes but unlike other mammals, echidnas have internal testes connected separately to a four-headed penissimilar to the hemipenes of snakes and lizards but joined at the base.
