The "stout infantfish" has been identified as the smallest, lightest animal with a backbone. The largest of only six specimen ever found is just 8.4 millimeters long. Stout infantfish swim exclusively near Australia's Great Barrier Reef and the Coral Sea. Scientists who studied the fish at the Scripps Institution of Oceanography point out that "roughly 500,000 of these fish weighed together would barely tip the scales at one pound."
