Like other positions — but unlike mammal sex — it’s aimed at letting the male fertilize eggs outside the female’s body. For years, scientists have thought frogs and toads used only six positions to mate. The sperm then trickles down to fertilize the eggs while she encloses them with her legs, the researchers suggest. Of the 15 egg clutches the researchers monitored for the new paper, 12 were eaten by predators before hatching. In an email, he also said he doubts the sperm is delivered to eggs from the female’s back.
