The tide was out but a little pond of saltwater remained near the mangroves. It looked very dull and murky but then we noticed several schools of tiny fish. I couldn't get a clear image on the LCD screen on my camera but took several photos anyway. After I'd downloaded them to the computer, cropped the image a little and corrected the colour balance I was amazed to see colourful little fish appear on the screen. I've no idea what they are.
And I don't know what this little skink is either. Two of them were on the wooden fence near the beach. (Update: Apparently it's a Wall Skink Cryptoblepharus virgatus.)
