When Frogs mate, the male frog tends to clasp the female underneath in an embrace called amplexus. He literally climbs on her back, reaches his arms around her "waist", either just in front of the hind legs, just behind the front legs, or even around the head. Amplexus can last several days! Usually, it occurs in the water, though some species, like the bufos on the right mate on land or even in trees!
While in some cases, complicated courting behavior occurs before mating, many species of frogs are known for attempting to mate with anything that moves which isn't small enough to eat!

The people of that time believed that living things, such as flies, arise from non-living things spontaneously. Fransesco Redi challenged this belief and set up the famous fruit fly experiment to demonstrate that life comes from pre-existing life, and not from non-living things such as meat and fruit.
