News Finding: Of course, you won't find either of those -- or any other undiscovered species -- in your backyard.
Paper Finding: Conclusions: Currently, between one-third and two-thirds of marine species may be undescribed, and previous estimates of there being well over one million marine species appear highly unlikely.
News Context: Add microbes and bacteria to that number and it jumps to 1 trillion. Of course, you won't find either of those -- or any other undiscovered species -- in your backyard. More than likely, they'll be found in habitats that are difficult for human scientists to explore -- like caves -- where species flourish under extreme conditions.
Paper Context: Thus, there may be 0.7-1.0 million marine species. Conclusions: Currently, between one-third and two-thirds of marine species may be undescribed, and previous estimates of there being well over one million marine species appear highly unlikely. If the current trend continues, most species will be discovered this century.
