THe Census of Marine Life has taken 10 years and cost $650 million dollars. It's first-decade report, issued today, finds the over 16,000 fish species have been described - but estimates 5,000 remain to be found. Some 250,000 marine species of all types have been described - a quarter of the estimated 1,000,000 out there. Ninety percent of the species in European waters are known, but only an estimated 20 percent off Australia. Think about that and marvel.
