The mysterious exploding toads

Just spotted on Y! news - Exploding Toads Puzzle German Scientists

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.”
