Bufo torrenticola Toad Multiple Amplexus

Shown here is a large female Japanese stream toad (Bufo torrenticola) with four males attached. These toads descended from higher ground to a river, where they gathered for a few days to spawn. Competition often takes place in this manner, with single males attempting to dislodge a male that is engaged in amplexus with the female. This is known as multiple amplexus, sometimes referred to as a mating ball or breeding ball. Photographed in Mie Prefecture, Japan.
