A team of European and Singaporean scientists has announced the discovery of the world's smallest fish, a creature about the size of a mosquito.
The team, writing in a British scientific journal, said the fully-grown Paedocypris progenetica is slightly less than eight millimeters long - making it not only the smallest fish ever found, but the smallest animal with a backbone.
The fish lives in the highly acidic peat swamps on the Indonesian island of Sumatra. The fish has an exposed brain and relatively large and muscular fins.
The scientists warn that development is threatening its habitat and say its survival is in jeopardy.
