Every year biologists across the planet document up to 20,000 new species. It's "a nightmare for tracking down and keeping score of all the new species every year." But last year saw the introduction of a new master database for biological classification--a kind of Wikipedia of life--called ZooBank.
The deep blue chromis (pictured) was the first new ZooBank entry. That distinction helped win the deep-reef fish a slot in the 2009 list of the top ten new species documented in 2008.
