Mutant Catfish

Rivers and oceans are often used as dumping grounds for unwanted goods - waste, byproducts, etc. In India, it is common to dispose of the dead in their rivers. Many funerals take place along their river banks, and when the cremation is almost over, the partially-burnt bodies are left in the water. Many believe that doing this will ensure that the soul of the dead will find its way to heaven.
An unforeseen side-effect made the headlines this week... After feeding on the bodies left in the India-Nepal border river, a type of catfish has turned its attentions to people who bathe in the waters in the hopes of fulfilling religious vows. The mutated fish has become the subject of a British documentary, after claiming lives in its locality for the past 10 years.
