Researchers with the Smithsonian have catalogued almost as many crab species on tropical coral reef bits measuring just 20.6 square feet (6.3 square meters) as in all of Europe’s seas, finds a new paper in PLoS ONE. The team used DNA barcoding to quickly identify a total of 525 crustaceans (including 168 crab species) from dead coral chunks taken from seven sites in the tropics, including the Indian, Pacific and Caribbean oceans.
