Crabs and Compasses

As a fitting coda to our trip to the Isle of Wight we had been invited to join some friends in Lyme Regis for the weekend. As I mentioned in my Isle of Wight post the eastern half of the English south coast was tipped on its end by tectonic forces so the geological history of that part of the world is exposed for all to see. In fact, moving from east to west is literally going back in time, heading as far as the Lower Jurassic era at Lyme Regis and Bridport, which is around 183-200 million years ago.

Those of you with a cinematographic interest may recognise the sea wall at Lyme Regis, it’s known as the ‘Cobb’, and was the location for the famous scene in The French Lieutenant’s Woman where Meryl Streep stands gazing out to sea. Which incidentally, is the only thing that myself and Meryl have in common, albeit for rather different reasons.

All our activities whilst we were in Lyme were marine orientated, I even managed to spend a couple of hours sea kayaking and peering into the crystal clear waters. The clarity of the water was incredible, it’s difficult to judge depth but I reckon at the deepest point I saw it was probably 15-20 feet deep. I could clearly see the bottom and the kelp fronds waving in the current, fish were darting in and out of the kelp and jellyfish were floating at the surface. I resolved to get up early the next morning and head out on the kayak to go snorkelling off the boat. So I got up and paddled out into the bay, but overnight a swell had risen which was swirling the sand around on the seabed and there was zero visibility in the water. So I need to make a return trip in the not too distant future so I can get in the water for a snorkel.

Glancing over the sea wall while the children were crabbing I saw this handsome compass jellyfish (Chrysaora hysoscella) gently patrolling the periphery. I’d seen several of them in the bay the day before when I was kayaking and they’re common around English shores. They can pack a nasty punch for any poor unfortunate who makes contact with the tentacles which can cause a stinging, burning sensation and red raised lesions on the skin. I don’t know if it can get worse than that but it’s apparently fairly unpleasant while it lasts.

The compass can grow up to 30cm across which is about the size of this one.

Eyeing up the progress of the crabbing exploits was a hungry herring gull (Larus argentatus). He was very interested in any potential meals the kids may catch for him and he was ready to swoop onto any escapees.

Looking eastward from the Cobb are more cliffs and the rocks here are full of fossils. We were staying in the white houses on the left and just round the corner from there lies a prime fossiling beach which alas we were cut off from by the tide. There were lots of folk busy cracking open rocks on the part that was accessible but I think most of the fossils from that spot had already been found.

The cliff on the right with the yellow patch is called ‘Golden Cap’ and is the highest point on the south coast of England, rising to 627 feet (191m).

The catch:

Shore crabs – Carcinus maena

The bait for the crabs was bacon, they’re mad for it, and there was a prize for the first crab caught, the largest crab caught and the most crabs caught. My daughter won, every time she dropped her line into the water it was a couple of minutes or less before she hoicked one out. So, much to the chagrin of the boys, she won all three prizes and was as smug as hell for the rest of the day!

And as the bucket filled with crabs the gull got braver and braver:

But he was to be disappointed. At the end of the competition our bucket of crabs was emptied into the water at the bottom of those steps and they all scuttled away to freedom.
