We can add to the fauna of New South Wales this brightly 

 coloured and variable Acanthochiles. It occurs generally on the 

 coast line in the vicinity of Port Jackson and as far south as 

 Bellambi. It affects sheltered pools and shows a preference for 

 stones overgrown with Halimeda, selecting a position at or near 

 the edge of the insertion of the stone in the sand, being rarely 

 found underneath.
