Continuing the theme from the two last posts with some ‘topside’ photos of rockpools. We had a very low tide recently which called for some rockpooling on our local shore here in Flushing. We looked (as always) for anything that we could find, but trying to get some ‘close-focus-wide-angle’ pics of fish with the Panasonic Leica 9mm lens was the main aim. Above a Male Tompot guarding eggs (see pic below) as well as a male Connemara Clingfish (no eggs spotted), recognizable by the bright red cheek markings. I have not been underwater very much, but have a bunch of macro photos of snails and stalked jellyfish that I will put on the blog next. (And remember, I post more frequently on instagram: @an_bollenessor!)




I tried my hand today at taking photos of rock pools above water – tricky! I used my Leica wide angle lens with a polarizing filter and a handheld strobe in a diffuser. It was fun playing around, although felt my back after an hour or so trying! It is difficult to keep the reflection of the flash out of the shot. The tide was not low so these are small, mid-shore pools dominated by coralline algae and some (fine) red seaweeds. Beadlet and snakelocks anemones, limpets, periwinkles, thick- and purple topshells are the most common animals. Some sunshine and blue sky – let’s see when I can try my hand at underwater photos again!



P.S. two extra pics taken a day later (without flash) near Bream Cove featuring an anemone-eating Aeolidia nudibranch.


Last weekend the weather was rubbish but the tide was low, and so we went over to our local beach in Flushing for some rock pooling. I did not bring the underwater housing, but just the macro lens and my cygnustech diffuser. Above a little clingfish – this could either be a Two-spotted or a Small-headed Clingfish; they are very hard to tell apart if they are not breeding males (see pic below for scale, I had to use the extra magnification of the Raynox clip-on lens for this one). Below three other fish species: a Tompot Blenny, a Common Blenny (or Shanny) and a Montagu’s Blenny (which is from an earlier post, but I wanted to complete the set here).















The Pheasant Shell is one of my favourite little critters in the rockpools in Falmouth. It is a bit weird to refer to these organisms as ‘shells’ actually, as they are living things and the nonliving shell is ofcourse only a part of them. The confusion extends to its scientific name: this species was previously known as Tricolia pullus, but has recently been split into a Southern European T. pullus species and a Northern European T. picta species. Perhaps the dust needs to still settle on that one.

I have taken these photos, on different occasions, with the mzuiko 60mm macrolens and the nauticam cmc-1 wetlens. The extra magnification the latter lens (screwed onto the housing) offers is great; although somehow I always want to get even CLOSER! I have not nailed the Pheasant Shell shot either. Reflecting on these pics I think I need to use a shallower depth of field to get rid of cluttered backgrounds. Next time.


The calcified operculum (the little door to close the shell) is clearly visible in the first photo above, as are the tentacles. On the second photo above you can even see that the left ‘neck lobe’ is more deeply digitated (fingerlike) than the right one. For more detailed (studio)shots of this and other molluscs please see Morddyn’s flickr account. I will post more macroshots of other mollusc species soon!

Last Friday I had a really enjoyable rockpool/snorkeling trip with my rockpool buddy David Fenwick (see his website aphotomarine for all your marine ID questions). Dave suggested we go far west, down to Sennen Cove where he knew about some interesting mini sea caves with jewel anemones and other things to explore. That is what we did, see the photo below!
Jewel anemones were indeed found in this spot….the water was too shallow to take a good photo though. I therefore jumped in the water where at first I got a bit seasick of all the waving Furbelows kelp. The water was noticeably colder than on the South Coast too. I discovered a nice deep gully with a whole variety of sea anemones growing on the vertical rock face. Orange, purple and green Jewel Anemones (Corynactis viridis) were common from 6 meters deep (at low tide). Very tricky for this middle-aged man to take good photos on one breath though! I was stumped by one white anemone but as Dave pointed out it looked like a Dahlia Anemone (Urticina felina) (and multiple ‘normally’ coloured individuals lived nearby so that makes sense). Finally a Sandalled Anemone (Actinothoe sphyrodeta) (my photos of the White-striped Anemone Anthothoe albocincta were unfortunately out of focus).




We had a blast and David found a Nemertean worm which might be new to the UK, or even new to science! It will find its way to aphotomarine eventually I am sure (check for ribbon worms here). I certainly like to go back snorkeling here some (windstill, swell-less) time.
When the viz is bad, I take my macrolens (sometimes with the Nauticam CMC-1 wetlens for a bit of extra magnification) out to the pools. Sometimes I stick to the surface of rocks and seaweeds (to look for stalked jellyfish for instance), but other times I turn over rocks under water to see what hides beneath. Quite a lot! There are larger animals, such as Topknots and different types of crabs (and Worm pipefish as pictured here) but mainly they are quite small (around a centimetre or even less). See the selection below (Tricolia, Bittium and Limacia were not from under rocks but I had to make the grid fit!).

























Although St. Martins does not seem to have any rockpools, the beach that was nearest to us (called ‘Lawrences’) has a stretch of rocks lying on the sand that can be turned over at low tide, and so we did! A nice find was a small Sevenarmed Starfish Luidia ciliaris (these can grow up to half a meter across, although you will not find them that size in rockpools). We also found a Bootlace Worm Lineus longissimus, which is (probably) the longest animal on the planet. These nermertean worms secrete a powerful toxin in their mucus, but luckily for us it affects arthropods and not mammals. They are not very rare btw, I see them here in Flushing and Falmouth too. It was about 5 meters long (without stretching it), but they can grow ten times the size of this! In the second photo you can see it in its natural habitat, under a rock, with some photobombing crabs and worm pipefish. Another cool find was a juvenile Conger Eel Conger conger. Otherwise we found the usual suspects, lots of crabs and a bunch of fish, see for a small selection below.
The wind has picked up and will ruin any chances of getting good seaweed shots this week. Too bad, but what can you do? A bit of rockpooling I guess. I took my son out to our local beach in Flushing where the rocks gently slope into Penryn River. Although there are no ‘proper’ rockpools, low tide gives access to a mixture of maerl sand and rocks that can be turned over. It is silty and definitely not very pretty, but there is always something to find. It was an especially good weekend for finding fish, seeing Shannies, Tompot blennies, Rock gobies, Gunnels, Worm Pipefish, Shore Rocklings and a tiny Eel, as well as Sea Scorpion eggs. (One Shanny was quite big and proceeded to bite my son’s hand; he was very brave and we slowly put it back.)
Invertebrates were plentiful too. The main mollusc here is the Variegated Scallop Chlamys varia, which is attached underneath every single rock. We found our smallest Great Scallop Pecten maximus as well. We found some Sea lemons Archidoris pseudoargus and lots of Yellow-plumed Sea slugs Berthella plumula (which apparently can secrete sulphuric acid when disturbed…). A small selection of what we found below, all pics taken with an Iphone.
It has been a wile since I last posted. This winter was long and dreary, the sea choppy and grey. I managed to do some rock pooling, and took a bunch of pictures, which I probably should have posted… The good news is that a mishap with my camera housing last year resulted in Olympus giving me a new model housing + a new model camera to fit (OMD EM1 mark 2) AND a new dome, lucky me! Regular readers of this blog know I get very excited in March, as this is when the seaweeds look at their best. This week the tides were low and the wind conditions favourable (the sun was not always out unfortunately), so I made sure to go in the water every day. The water is cold (9C), especially after being in for 2 hours, but it is all worth it. The seaweed growth was lush, with species literally growing on top of each other. I tried to shoot with strobes, but this proved too difficult and switched to natural light. Keeping ISO at 200, I aimed to lower shutter speed to 1/30, managing an F stop of between 5 and 8, depending on cloud cover. I now get the hang of that, but it is difficult to keep photos well-exposed, with enough depth of field and maintain sharpness. Below some examples. I am lazy and will not add seaweed names (but see the Seaweed Gallery page at the top if you are interested). When the tides are low again at the end of next week I hope to go out again!
