World's smallest fish discovered in Indonesia

Pictures of the just–announced discovery, which lives in an acidic peat swamp on the island of Sumatra, appear above and below.

A member of the carp family, it is called Paedocypris progenetica.

The fish has a see–through body, boneless head and grows to a length of 7.9 mm.

For reference, that's approximately the width of a wooden pencil, or half the diameter of a dime.

The discovery, by a team led by Dr. Maurice Kottelat of the National University of Singapore, was reported yesterday in the Proceedings of the Royal Society.
