Spring arrives early in the rock pools

There’s no better way to explore the shore than with a group of experienced rock poolers. During this month’s big spring tides, I was privileged to join a small, dedicated team to survey Hannafore Beach in Looe. Best of all, David Fenwick who runs the brilliant Aphotomarine website brought along his newly-converted marine laboratory camper van for a test run.

A few weeks on and I’m still downing hot chocolate to recover from the cold (any excuse!), but this was a priceless opportunity to expand my knowledge and encounter new species. Over the week we recorded over 230 species, some of which I never knew existed and I finally found my first Snake pipefish.

Day one got off to an inauspicious start. David’s marine lab van broke down on its way to the beach, meaning he missed the best of the tide that day. Those of us who did make it had to leap back into our cars to take refuge from the hail before we’d even got our boots on.  Despite the wind chill, we were soon in full swing. Incredibly, the pools were full of signs of spring.

Scorpion fish lay their clusters of yellow glitter-ball shaped eggs earlier than most other species. In some, the baby fish were already taking shape and hundreds of eyes gazed into my camera lens.

Along the grooved bellies of some of the worm pipefish, there were also lines of eggs. Like seahorses, it is the male pipefish that carries the eggs until they hatch.

It’s hard to think of slugs as migratory animals, but several sea slug species have made their annual journey onto the shore to breed. We saw lots of the rarely-recorded slug Aeolidella alderi. My friend Jan from Coastwise North Devon found one that had been chomping on a dark anemone. The colour had passed into the cerrata on its back so that instead of the normal bright white, this one looked almost red.

Another had distinct yellow tips to its antenna and cerrata. This species always has a ring of short white cerrata below the head, making them look like they’re wearing a white ruff.

Nearby, a relative of Aeolidella alderi, the more common ‘Great grey sea slug’ (Aeolidia sp. probably filomenae) is feasting on an anemone. This hungry slug isn’t holding back and has dived headfirst into its feast.

Yellow-clubbed sea slugs (Limacia clavigera) were also out looking for mates. They’re not easy to spot when the tide’s out, as they look like minute splodges of white jelly on the rocks. Once in the water, they are transformed, with spiral rhinophores sprouting from their heads and robust yellow-tipped cerrata sticking out from their heads and bodies.

When, towards the end of day 2, I glimpsed a shape gliding through the seaweed my heart leapt. I’ve been looking out for this fish for years to no avail, but this one was hovering above my foot. Snake pipefish, like other pipefish, freezes and relies on its fabulous camouflage to escape predators.

I was able to reach into the water and lift it out for a quick photo. It wasn’t slippery to hold, but it wound its body around my arm so I had to overcome the powerful urge to squeal and drop it.

Snake pipefish can grow to 60cm and have pale vertical lines down their bodies so are easily recognised. They like to live among sea grass beds so are not commonly seen on the shore.

Inevitably, other fish were more evasive. David saw a Conger eel among the kelp, but it slipped away.

Among many amazing and less-common species, David Fenwick showed me this rare prawn, Caridion steveni, which appeared to have an especially short, blunt ‘nose’ (rostrum) compared to some other species. Its bright red pigmentation helps it blend in to the seaweeds.

Among the weeds on the rocks, tiny spider crabs were everywhere, only visible when they moved their spindly legs. Even when I take close-up photos it can be hard to make out the shape of the crabs.

Junior spotted a crab with an even more amazing disguise. We were looking under a boulder when he gasped and pointed at a seaweed-covered stone.

‘It’s a crab, I saw it move,’ he whispered, as though it might hear him and realise the game was up.

Whichever way I looked at the stone that Junior was waving his finger at, it still looked inanimate. It was only when I picked it up that I felt the sharp spines of the Common spider crab (Maja bracchydactyla) lurking below the seaweed camouflage. We turned it over to see the crab’s legs neatly tucked under its carapace. Junior delighted in placing the ‘stone’ back in the water to watch it sprout legs and scuttle away into the safety of the seaweed.

Even up close it was hard to tell this is a crab - but I could feel the sharp spines on its shell and the legs began to move.

On day one I reached, or frankly surpassed, my cold tolerance limit. By the end of the week I  was only able to function by keeping my hands thrust deep inside my scarf to warm them against my neck. I must have ressembled a trussed chicken, but there was no point caring. As always, the rewards outstripped the pain.

Next weekend we’re expecting some huge spring tides in Cornwall, and yet more freezing winds, so you know where I’ll be.

I’m excited to be leading a couple of fabulous training events on Friday 2 March in Falmouth and Sunday 4 March in Looe. Maybe I’ll see you there? Wrap up warm!

Giants of the Cornish rock pools

Last week I shared with you the miniature world of the sea slugs, so this week I’ll super-size things and bring you some big fish. Silly-season reports of Great-white sharks often hit the headlines in Cornwall, but I prefer rock-pool giants; they’re not made up, and you can get close to them without having your leg bitten off!

Cornwall is brilliant in all sorts of ways, our network of local, grassroots marine conservation groups being just one of them. The public launch, last week, of the new Three Bays Wildlife Group brought experts and volunteers together and gave me a chance to explore some new beaches in the St Austell area.

Judging by the squeals of excitement from the children and adults alike, the crabs, pipefish, prawns and anemones we found at the main rockpool ramble on Portmellon beach near Mevagissey went down well. By the end of the day, the local group had recruited lots of potential new volunteers.

My First Fox Club Expedition To Porth Mear

It’s the middle of the night and I’m convinced there’s something wrong with my eyes. I’ve unplugged my phone, tried blinking several times but I’m still seeing flickering lights and flashes. Finally I twig what’s going on and open the curtains to reveal incessant sheet lightning.

My first thought is that it had better stop by the morning, else no-one will turn up to my first rock pooling event at Porth Mear with Fox Club, the junior branch of the Cornwall Wildlife Trust. As a child, I was a keen member myself so I’ve been looking forward to this for months.

By the morning the lightning storm has given way to wind and rain, but conditions are less than inspiring. It’s amazing anyone shows up for rock pooling, but a few hardy well-wrapped-up folk do, as does a lovely volunteer assistant. Continue reading My First Fox Club Expedition To Porth Mear

Cross-Border Rockpooling with the Porcupine Marine Natural History Society

It sometimes feels like I don’t get out much – either socially or out of the county (Not that it’s a hardship to be in Cornwall!). So, I could barely contain my excitement at having the opportunity to attend the Porcupine Marine Natural History Society Conference in Plymouth. I packed my passport and set forth across the Tamar.

Not only did I mingle with the most amazing bunch of fellow marine wildlife obsessives and hear their latest findings, but the third day of the conference was spent rockpooling at Wembury in South Devon.

While the environment at Wembury is similar to my home patch in South East Cornwall, a major difference is that Wembury has a marine centre, staffed by lovely people from the Devon Wildlife Trust. The centre promotes marine conservation and runs all sorts of public and educational events. It also provided a handy indoor base to set up some microscopes and a refreshment station. Luxury after my recent all-weather forays! Continue reading Cross-Border Rockpooling with the Porcupine Marine Natural History Society

Sharing the Love of Rockpooling

This week I’m planning rockpooling events for next year and adding identification pages to my website….

Yesterday it was so foggy you couldn’t see the sea in front of your wellies. Before that it was raining; before that it was blowing a gale and on the one day the sun came out I was nowhere near the beach. It’s not bad for eggcase hunts – which Cornish Rock Pools junior loves – but that’s about it.

This time of year, when the short days and inclement weather make even die-hard rockpoolers like me reach for the duvet, I turn to flicking through the 2017 tide table and dreaming of sunny days and gleaming expanses of shore.

Is it too early for New Year’s resolutions? Mine is to spend (even) more time sharing my love of rockpooling with others. I’ve put all the Looe Marine Conservation Group rockpooling events in my diary and I’m also hoping to volunteer with the utterly fabulous Fox Club (the junior branch of the Cornwall Wildlife Trust), helping to run events around the county. Then there will be other events for the local scouts and home educating groups to fit in, and who knows what else. Continue reading Sharing the Love of Rockpooling
