Baby biodiversity in the ocean

'Python of the Sea' Study Highlights How Marine Biodiversity Can Be Dramatically Underestimated

Most ocean life remains to be discovered. Because fish and many other animals that live in the ocean often have larvae or other, microscopic life stages that drift freely in ocean water, counting species by genetic barcoding of plankton samples adds to counts of species recorded as adults and is a highly efficient way to understand what lives in the ocean and how biodiversity changes as we modify the ocean environment
