The Stalked Jellyfish World Record (for Portwrinkle)

Calvadosia cruxmelitensis stalked jellyfish with another species - Haliclystus ocroradiatus - next to it.

β€œSo is this a world record?” Cornish Rock Pools Junior has just found 26 stalked jellyfish and is feeling rightly proud of himself.

β€œIt’s a record for Portwrinkle,” I tell him. β€œThey’ve never been found here before.”

β€œBut is it a world record?” he insists.

I take a moment to consider this. Only a moment, because my hands are frozen from holding my camera in the water and another snow flurry is starting.

β€œYes,” I say. β€œYou now have the world record for finding stalked jellyfish in Portwrinkle.”

From the leaping and cheering, I’d guess he’s satisfied with that.

If you follow this blog regularly, you may be starting to find the recent focus on stalked jellyfish a touch tedious. You wouldn’t be alone. Although I remember the excitement of finding my first one, the beauty of its markings and delicate tentacles, after seeing scores of the things and spending hours in freezing pools staring into the seaweed, they’re losing their edge.

Still, given that one species is a recognised feature of my local Marine Conservation Zone and two more species have potential to be added, any evidence that they’re here might help to protect them. So far, all of that evidence has come from beaches in walking distance of my home in Looe because I’m pretty much the only person recording them. When I took Natural England on a stalked jelly hunt at Hannafore, they asked if I could help them search beaches at the opposite end of the Looe and Whitsand Bay Marine Conservation Zone.

It seems such a great idea. Leaving home in a snow flurry though, I begin to question my sanity. I’m not sure, in such circumstances, whether it’s a good thing to have a wonderfully supportive partner and son, but neither of them bat an eyelid at the weather. Wearing boots, waterproofs, scarves, hats, gloves, and just about every item of clothing we possess, we head for Portwrinkle beach.

Junior becomes less supportive when I find the first stalked jelly. I hadn’t realised how badly he wanted to find it himself and wish I’d kept quiet about it, but after 45 minutes of fruitless searching it seemed like the sort of breakthrough worth announcing.

The first find is a Haliclystus octoradiatus - the 'blob' (primary tentacle) between each pair of tentacle arms helps identify this species.

β€œI’m useless,” he sighs. β€œNow I won’t get the world record.”

I try to reassure him. Surely we are a team and finding them together? But nothing is working. A little further down the rocks, where the pools meet the sea, I notice an arc of rocks forming a shallow, rock strewn bay with plenty of weed.

β€œCome and try over here,” I suggest.

He kicks at the rocks and mopes over to where I’m standing.

β€œJust try,” I repeat.

It only takes a second.

β€œHere’s one,” he screams, his voice easily reaching his Dad, in the distance across the rocks.

One of Junior's many, many finds. A Calvadosia cruxmelitensis stalked jelly. The white spots (which are stinging cells) trace the outline of the tentacle arms and form a 'Maltese cross'.

Seconds later, while I’m crouching to photograph his find, he tugs at my shoulder. β€œI’ve found another one.”

Junior finds another species, the Calvadosia campanulata, which gets its name from its bell-like shape.

And so it goes on; Junior’s voice becoming more excited with every find. I can’t keep up. There are so many stalked jellyfish that Junior is finding three in the time it takes me to take a photo of one. They’re everywhere. As I’m taking the photos I keep finding yet more.

Now, I don’t like the cold. I may have mentioned that before? My hands, in particular, don’t cope well with being plunged into icy water or drying in an easterly wind. By the time Junior has racked up 26 stalked jellies and I’ve found a further 15, the pain in my fingers is becoming all-consuming.

Fortunately, by this time, the boys are more than ready to go to the pub for lunch.

β€œHave people actually looked for stalked jellyfish here before?” Junior asks as we head for the car.

β€œYes, I think so,” I say.

β€œSo it really is a proper world record?” he asks.

β€œYes, I suppose so.”

Junior glances around him and narrows his eyes at a dog walker.

β€œWhat’s up?” I say.

β€œI don’t want lots of publicity. Do you think the newspapers and TV will find me? I’m not going to tell them where the stalked jellyfish are.”

I assure him that only people who care as much as we do about nature will ever read my blog.

He thinks about it for a moment and nods.

Despite the cold, I sneak in a few photos of other species. This is a baby sea hare (Aplysia punctata).

Tomorrow I’ll be off to the rock pools again, on the north coast this time, and I’ll be taking a day off from stalked jellyfish!

    I think you have a marine biologist in the making!

      Apparently so – he nearly popped with excitement. Despite that I think he’d still prefer to be a volcanologist! Ah well… πŸ˜€
