World's Tiniest Vertebrate Found

foidulus writes "The BBC reports that American scientists have identified the world's tiniest fish living around Australia's Great Barrier Reef. It is also the tiniest animal with a backbone. The male of the stout infantfish is only about 7 mm(or less than 1/4 of an inch) long. It has a life span of only around 2 months which scientists say may be an advantage because it can evolve rapidly."
