Happy International Day for Biodiversity 2012! Celebrate marine creatures today! What a fantastic opportunity to raise global awareness of the many issues facing the world’s marine ecosystems, and to encourage practical action to protect and conserve them.

From tropical oceans and coral reefs, to deep-sea vents and the ice-strewn waters of the Arctic and Antarctic, marine ecosystems are hugely diverse. The total number of known marine species are estimated to range from 250,000 to at least a million. Some scientists believe that the actual figure could be twice as high!
