When I was little, I was always puzzled after the summer holidays back at school when my friends would say what a great time they had on holiday; on the beach, in the sea, suncream, sandcastles, ice creams, the lot.
Now we also had a great time on holiday, and went to the seaside, but our experiences in the north of Scotland on the Moray Firth were more in the way of stony beaches, cutting north wind, terrific waves from the angry stormy sea, and - of course - rockpools.
These days, I prefer my beaches sandy, and my seas warm, and if you can conjure up a palm tree or two, so much the better.
But I am still fascinated by rockpools - those micro worlds with their miniature creatures, and here on holiday, the the rocky headland by a favourite beach provided just the thing.
With the light reflecting in the water, it was nearly impossible to take photos of this rocky 6' by 4' world - there was a shoal of fish in the 2' depths, mini clams on the shallow slope, a sea slug which looked like a piece of seaweed marching along the sandy section, and a catfish keeping to the miniature vertical side, darting through the inch high sea grass waving in the ripples.
I was so preoccupied with this microcosm that I nearly missed this chap - 8" toe to toe, but fortunately for me, heading away to the waves.
I love it - my week 40 Challenge, done!
