Air date: Aug 21, 2011

Humans have long wondered if the universe may harbour other intelligent life forms. But perhaps we need look no further than our oceans? Whales and dolphins, like humans, have large brains, are quick to learn new behaviours and use a wide range of sounds to communicate with others in their society. But how close are their minds to ours? In the Bahamas, Professor Denise Herzing believes she is very close to an answer, theorising that she will be able to hold a conversation with wild dolphins in their own language within five years.
