The Census of Marine Life - a ten-year effort by scientists from around the world to answer the age-old question, “What lives in the sea?” It was an international effort to asses the diversity, distribution, and abundance of marine life in our ocean, and the project offically concluded in October 2010.  

In this video co-produced by the Census of Marine Life and National Geographic, dive down to the depths of the ocean and observe some of the fascinating creatures that scientists documented during the Census.  Watch the piglet squid, snake pipefish, sea angel, and football octopod swim by your screen in this video.
