Exploding Toads Puzzle German Scientists

BERLIN (AFP) - Hundreds of toads have met a bizarre and sinister end in Germany in recent days, it was reported: they exploded.



According to reports from animal welfare workers and veterinarians as many as a thousand of the amphibians have perished after their bodies swelled to bursting point and their entrails were propelled for up to a metre (three feet).
It is like "a science fiction film", according to Werner Smolnik of a nature protection society in the northern city of Hamburg, where the phenomenon of the exploding toad has been observed.
"You see the animals crawling on the ground, swelling and then exploding."
He said the bodies of the toads expanded to three and a half times their normal size.
"I have never seen such a thing," said veterinarian Otto Horst. So bad has the death toll been that the lake in the Altona district of Hamburg has been dubbed "the pond of death."
Access to it has been sealed off and every night a biologist visits it between 2:00 and 3:00 am, which appears to be peak time for batrachians to go bang.
Explanations include an unknown virus, a fungus that has infected the water, or crows, which in an echo of the Alfred Hitchcock movie "The Birds", attack the toads, literally scaring them to death.

Update:
BERLIN - More than 1,000 toads have puffed up and exploded in a Hamburg pond in recent weeks, and scientists still have no explanation for what's causing the combustion, an official said Wednesday.
Both the pond's water and body parts of the toads have been tested, but scientists have been unable to find a bacteria or virus that would cause the toads to swell up and pop, said Janne Kloepper, of the Hamburg-based Institute for Hygiene and the Environment.
"It's absolutely strange," she said. "We have a really unique story here in Hamburg. This phenomenon really doesn't seem to have appeared anywhere before."
The toads at a pond in the upscale neighborhood of Altona have been blowing up since the beginning of the month, filling up like balloons until their stomachs suddenly burst.
"It looks like a scene from a science-fiction movie," Werner Schmolnik, the head of a local environment group, told the Hamburger Abendblatt daily. "The bloated animals suffer for several minutes before they finally die."
Biologists have come up with several theories, but Kloepper said that most have been ruled out.
The pond's water quality is no better or worse than other bodies of water in Hamburg, the toads did not appear to have a disease, and a laboratory in Berlin has ruled out the possibility that it is a fungus that made its way from South America, she said.
She said that tests will continue. In the meantime, city residents have been warned to stay away from the pond.
