Tom Trnski of the Australian Museum in Sydney holds a vial with a specimen of the Schindleria Brevipinguis or Stout Infantfish, believed to be the world's smallest vertebrate Wednesday, July 7, 2004. The tiny fish reaches no more than 7 to 8 millimeters (0.27 to 0.31 inches) long and was discovered 20 years ago and scientists have studied the minute minnow to better understand its life cycle before releasing the news of the discovery.
