We’re on a stomp about the beaches between Looe and Seaton, enjoying a patch of sunshine. “Watch out for Portuguese Man O’War jellies,” I warn Junior as we cross the muddy sand at Millendreath. I know there have been reports of them washing up all around the south west coast over the last few weeks, but there are none today. Inevitably, it’s something else that nearly gets me.
In a sandy pool at the sea’s edge, a flicker of movement catches my eye. It happens so quickly I can’t be sure there’s anything there but the sand is settling, suggesting something has just buried itself.
I call Junior over to look and I crouch low, reaching a hand to the water’s surface. If I can scoop the sand up from underneath I might be able to gently lift out the creature. Having seen plenty of well-camouflaged dragonets scooting about the pools today, I expect this to be another one. I stop short and stare into the shimmering pool.
It’s a good call. You never know what might be lurking in the rock pools. Near where I saw the movement is a sandy coloured lump. I think I recognise the shape, but it’s only when I lower my camera into the water and zoom right in that I can be sure. A Lesser weever-fish is staring down my lens, its frog-mouth gaping slightly, the rest of its body buried in the sand. Before I can take a shot it’s gone.

The Cornish summers are anything but predictable. One day I’m sweltering in shorts and beach shoes and the next I’m shivering in waders and a thick jumper. Although the showers are back with a vengeance, there’s always something to be found if I can make it across the rocks without breaking an ankle.
My first outing is to the rocks beyond East Looe beach and I’m pleased to come across a new colony of St Piran’s hermit crabs on the mid-shore.
They’re becoming a familiar sight around Cornwall and I’m starting to recognise them from the tips of their red legs, before their chequerboard eyes and equal-sized claws emerge from their shells. Continue reading Wrasse and wrack→
I doubt anyone in Looe can have missed it – the moment today when Cornish Rock Pools Junior found his first stalked jellyfish. His scream of, “I’ve actually found one!” rang across the beach and echoed off the hillside.
His first find was closely followed by his second, next to which was a third. A volunteer from Looe Marine Conservation Group found a fourth. The Natural England team found some more and by the time we were done we recorded a whopping 26 Stalked jellyfish.
As all our records today were of two species (Calvadosia cruxmelitensis and Calvadosia campanulata) I’m feeling hopeful that they may soon be added as recognised features of the Looe and Whitsand Bay Marine Conservation Zone.
In December, good tides, mild temperatures and low winds coincide about as often as it snows on the Cornish coast (i.e. about once every ten years). Amazingly, today was one of those rare occasions and the rockpools were in impressive festive colours. What could be more Christmassy than this Dahlia anemone?
We were doing so well with our stalked jellyfish survey that I didn’t feel too bad about getting distracted. When I spotted a wriggling piece of seaweed, I chased it across the rocks.
As I suspected, under the seaweed decorations was a small spider crab species. This one was a Macropodia deflexa, a long-legged spider crab.
Relying on their camouflage, scorpion fish were lying still among the seaweed, allowing us to come right up to them.
It was a huge relief that everything turned out so well for our Stalked jellyfish survey. Had the conditions been less favourable we’d have been more likely to find none at all. 26 was an amazing total.
I needed my hot chocolate afterwards, but it was an afternoon well spent with some fabulous people. And tomorrow the forecast is even better… I’ll let you know what I find!
My local area is special and it’s partly down to some fabulous little jellies we find here.
Looe and Whitsand Bay was one of the first to be designated a Marine Conservation Zone (MCZ) three years ago. Apparently Ocean quahog (a clam shell), pink sea fans, pink sea fan anemones and a stalked jellyfish species (Haliclystus sp.) can all be found here.
I’m hoping we can add more species to that list. There have been some local records of giant gobies, which are one of the MCZ ‘feature’ species and we’ve found three other species of stalked jellyfish on our beaches.
The problem with stalked jellyfish is that they’re tiny and seaweed coloured. In theory, the winter die-back of seaweed makes them easier to see, but Cornish winters don’t often provide the calm conditions you need to spot stalked jellies. Consequently not many people see them and even fewer people record their discoveries on ORKS – so please, please do share your finds!
In a quest to add more evidence that these species are present in significant numbers, I take Cornish Rock Pools Junior for a wander through the pools at a quiet local bay.
I find it’s best to focus on nothing else if I’m going to find stalked jellies. The problem is, as anyone who’s seen me in the vicinity of a chocolate hobnob will know, that I have no willpower. So, I spend the first half hour snapping this gorgeous strawberry anemone as it stretches its tentacles towards the last of the autumn sunshine. Continue reading On a stalked jellyfish mission…→
Things have been quiet on this page the last couple of months. Cornish Rock Pools Junior, Other Half and I took an extended holiday to visit the towns and beaches of Brittany. As always our travels had a bit of a marine theme…
“Est-ce que c’est un anémone?” the eager child in the dark-rimmed spectacles asks. We explain what a ‘stalked jellyfish’ is to the class of seven-year-olds. “Jellyfish!” they chant.
Between fascinating excursions to the fire station and the sardine factory, we are giving impromptu English lessons to a class of primary school students during our twinning visit to Quiberon in Brittany.
It’s funny how the summer days float by. The house has been practically bursting with people for weeks now and I haven’t found the space to write about our many beach trips, but August still feels like a lazy month.
It reminds me of my childhood summers; a jumble of paddling, swimming, rockpooling and finds. Only I’ve just turned 40 and now I’m the one remembering hats and towels, preparing picnics and being called on constantly to help build dams or identify creatures. Every few days I realise that I’ve failed to take many photos and still haven’t blogged anything I’ve found. It’s just the way August goes.
The warm waters are drawing in all sorts of creatures at the moment. The north coast especially is teeming with jellyfish. Harmless Moon jellyfish have washed up in their thousands. These transparent little jellies have four mauve circles in their centre in a pattern that reminds me of cucumber slices (OK, that’s probably just me).
Other jellyfish that have mild stings, like the compass jellyfish are also washing in and I think my thigh met with one of the many blue jellies in the water at Mawgan Porth a couple of weeks ago from the unattractive rash I developed! On the plus side, some friends found a spiny starfish in a pool at the top of the mid-shore pools, which looked like it might be feeding on the stranded jellies.Continue reading Summer Lazing in Cornwall’s Rock Pools→
