    About Common Frog eggs

    There's no place like home for common frogs, which typically return each year to the same spawning sites where they developed. During mating, the frogs embrace so that males can fertilize eggs while the female is laying them. She can spawn up to 2,000 eggs at once, but of that huge amount only around five will become fully grown frogs - the majority being picked off by fish, birds and snakes. The eggs are surrounded by a mass of clear jelly, which acts as a protective nest and floats on the surface of the water so the sun can warm the developing embryos. Depending on the temperature, it can take between 2-5 weeks for the tadpoles to wriggle free into the water and join the other pond life, most of which lies ready to make a meal out of the new residents.
