The weather blowing from the north-west, (a hot, dry wind buut one that
whipped up the swells at Shelly Beach) Nik - my son - and I took ourselves
off to Fairlight, a beach inside the Harbour that faces directly towards
Sydney Heads.

It was high tide and flat calm, but the brown algae still hanging around
reduced the visibility to a maximum of three-metres.  The effect of that is
that we tended to focus closely on looking for the smaller things.  We saw
dozens of nudibranchs; lots of colourful soft corals and two Port Jackson
sharks under different overhangs.  I determined to come back with at least
one picture of what we'd seen.  Pushing the camera out in front of me, I
wriggled under the ledge and up behind one of the Port Jacksons.
Regrettably the space was too small to manouvre properly.  Nevertheless, I
managed to take three pics of a sharks bum!  I'm not certain, but I think
that I may have discovered a new way of identifying individual sharks.  "Ah!
Yes!  Looking at the freckle", (a polite term for bum-hole), "on that shark,
I can tell you that it's name is Eric and that it was last seen at Fairlight
on the 8th October."   :-)))
