Best Friends

S1 E5: Barney Harwood and Gemma Hunt discover the world of Australia's Barrier Reef. The ocean world is full of fantastic fishy friendships, but just like our world some friends are better than others and some friends you could just do without. From the cosiest couples to the most peculiar pairings, these friendships are super strong because often these bezzy mates need each other to survive in the fish-eat-fish world of the Barrier Reef. Sea creatures have funny ideas of what makes a good friend. You might not be too impressed if your best mate dressed in exactly the same clothes as you, used you as a body guard or let you do all the hard work, but in the ocean depths things are a little different.
