1966. A small, nondescript bend in the river at Port Hacking is coming to prominence as a remarkably diverse area with particularly high conservation values. In the words of Clarrie Lawler, Secretary of Underwater Research Group of NSW at the time, the “combination of a deep submarine cliff, strong currents and unpolluted water have resulted in an extremely rich growth of marine invertebrates with a resulting large population of fishes… During the early months of 1965 (we) began diving this area and were astonished at the profusion of marine fauna given the seemingly ordinary estuarine situation”.

In a recent edition of Nature NSW we published a Creature Feature on nudibranchs. These curious, diverse molluscs are a favourite find for divers. They are also excellent indicators of climate change, thanks to their visibility, ease of identification and seasonality.
