Mystery of German exploding toads

BBC NEWS: "Toads in an area of northern Germany are being killed off by a mysterious disease - they are exploding. Thousands of the amphibians have died in recent days in a pond in Hamburg's Altona district, with their bodies swelling to bursting point. The toads' entrails are propelled for up to a metre (3.2ft), in scenes that have been likened to science fiction. Scientists are baffled. Possible explanations include a unknown virus or a fungus in the pond."
