Scientists say it's time to rewrite the textbooks. The Census of Marine Life, released Monday, shows that the polar oceans are home to far more species than had previously been thought. The new census, an international effort to catalog all ocean life, documented 7,500 species in the Antarctic and 5,500 in the Arctic. Researchers were also surprised to learn that as many as 235 species are found in both polar oceans.
