There are more species of fish in Sydney Harbour than in the entire Mediterranean Sea - over 550 species in fact (and that's just the fish). There are even more little critters and a whole bunch of bigger stuff. Here is a selection of our favourites. Most are Sydney locals and were photographed at home. The rest were just visiting and were snapped during chance encounters.
