Falmouth Rockpooling

Some photos from Last Sunday at Castle Beach in Falmouth. Above, the periwinkle Littorina littorea, which aggregrates in great numbers on the upper shore. Below, three echinoderm cousins: a Cushion star Asterina gibbosa and a little Sea cucumber Pawsonia saxicola with a Brittle star in the background. It was the first time I saw this beautiful colour variant of the Risso’s or Furrowed crab Risso pilipes. More common is the very similar Montagu’s crab Risso hydrophilus, there are usually 5-10 individuals under a single rock. The small ones especially come in a range of colours that make them excellently camouflaged against the pebbles. Next a juvenile Shanny Lipophrys pholis, a detail of a Corkwing wrasse (I could pick it up, that is how low the tide was) and a shot of the beach, showing the versatility of the mzuiko 60mm lens.

Rockpooling in Flushing

Some pics from today at Flushing Beach. Above, a pair of Green shore crabs Carcinus maenas, below two Furrowed crabs Xantho hydrophilus. (I probably should have gone for a whole crab series, as I saw several other common species…) Instead I took loads of random photos, of things that were 150 mm to things that were only 5 mm, with varying success. For instance of a Painted Topshell Calliostoma zizyphinum on the invasive Bryozoan Watersipora subatra. Also the underside of the urchin Psammechinus miliaris, showing its mouth (Aristotle’s Lantern). Photobombing top left is the commensal worm Flabelligera affinis (which I noticed as well the last time I took a version of this picture). Bit random but it was fun practicing. It actually is more difficult to take photos abovewater compared to underwater due to the glistening and the awkward position kneeling on wet gravel/rocks. Next time I might try a tripod (ideally remote flash would be used but I do not think I am going to invest in that). Btw, if you are on instagram, I also post pics as @an_bollenessor.

Silver Steps Diving V

Yet another solo dive (I know, I know, not ideal) this Thursday morning before the easterlies are kicking in. Actually, the water was already choppier than I expected, but for macro photography the viz is not as important. I did not get ‘the’ shot but it was a nice dive all around. I discovered a little swim-under and saw lobster, rock lobster (craw fish) and a huuuuge conger eel. I was focusing on a little tunicate when I looked up and saw it looking back at me from not very far away at all. Its head was as big as mine. I slowly swam backwards, thinking of this encounter…..overall they do seem to be aggressive towards people though, and with my fisheye lens this could have been a really good shot. This later happened again, this time a smaller individual but still sizable. I did not stick my macro lens up its nose but grabbed a halfhearted shot with a passing by Twospot goby almost in focus to give an idea: Some macro shots: again a Twin fan worm Bispira volutacornis and a new one for me, a big bright red Protula tubularia. It would be nice to get some abstract close-ups but these are excellent living motion-detectors so it is difficult. There are some amazing colours under the rock overhangs and I would like to try some more abstract photos such as this Spiny starfish or this Didemnun colonial seasquirt and other encrusting animals (and plants). No diving/snorkelling this weekend because of the wind, but glad I could put a couple of dives in these past weeks, and I will make an effort to go a lot more weather permitting!

Silver Steps Diving IV

A solo dive early evening at the Silver Steps site. It was a couple of weeks I last went, and this time it was already dusk when I entered the water. My intention was to find cup corals and other small creatures growing on rock overhangs below the kelp line. The viz was good and sure enough I found what I was looking for: Devonshire cup coral Caryophyllia smithii, a solitary stony coral which is relatively common. They are very beautiful and the right size for the macro lens. I will definitely go after them again. Other finds were a golfball sponge Tethya aurantium, a baby Longspined seascorpion (this shot had potential, but it swam away unfortunately), a tunicate and a Painted topshell (very common). At the end of the dive unfortunately it was getting too dark to find objects or too properly focus; I need to sort out a dive light!

Variegated Scalllop Mimachlamys varia

A quick snorkel in the rockpools today. Tried to photograph some gobies and prawns but they were not very cooperative. I noticed a small clam under an overhang: the Variegated scallop Mimachlamys varia (old name: Chlamys varia). This species occurs quite commonly attached under rocks here, and although it can have all kinds of amazing purple, yellow and orange colours it is usually a dull brown. I managed a couple of OK shots; it is fun to see the rows of eyes. Definitely worth trying again (and going for a much bigger Scallop Pecten jacobaeus while diving should be fun too).

Silver Steps Diving III

I will keep this post short, as my third Silver Steps shoredive of the year was a week ago. As you can see above, my dive was made by encountering the beautiful nudibranch Antiopella cristata (although I prefer the old name Janolus cristatus…). My camera battery strangely gave up straight after taking these pics (argh!), otherwise I would have bothered it for at least another ten minutes! The 60mm lens is great. Look at the European cowrie Trivia monacha below which is less than a centimeter in length. Not a great shot but it shows that it is possible. Finally, a common Phoronid worm Phoronis hippocrepia (Thanks Allison, please check out her great blog Notes from a California naturalist). I hope the wind will die down and I can go back soon.

Silver Steps diving II

Another Silver Steps shore dive with @shannonmoranphoto and her fellow student Chris on Friday. The conditions were not as good as last time: low viz and a bit of a swell. I had set my camera to a longer focal range to try to take pics of cuttles or larger fish but that did not work out (with better conditions it still might not work out!). I could still shoot macro so that is what I did. Above to Devonshire cup corals Caryophyllia smithii. Pretty decent, but I know I can get a better close-up; I will try again Monday! I will have another go at the one resident Cray (or Craw) fish, which lives very shallow. I will also try the Twin fan worm Bispira volutacornis again, as I think a shot filled with just the fans (and not assorted bits of seaweeds etc) could be really nice. I might try free-swimming fish if they come close, as did this Poor cod Trisopterus minutus. Below some before- and after postprocessing. Just the jpegs in Windows Photos, nothing fancy. A bit of cropping, increasing clarity and contrast works wonders. Only when I have a really good photo I will invest time processing raw files in Photoshop. First the best photo of the dive: a Black-faced blenny Tripterygion delaisi (a female or possibly a non-breeding male). Next, a common Edible crab Cancer pagurus and finally a Twospotted goby Gobiusculus flavescens.

Silver Steps Diving

Finally a shore dive yesterday evening, it has been a long time. I partnered up with buddy Shannon via instagram (@shannonmoranphoto). Instagram has been a really nice way to learn about photography from likeminded folks (such as @danboltphoto and @malcolmnnimmo). We dived (dove?) Silver Steps in Falmouth, about which you can find a bunch of old snorkelling and diving posts on the blog if you are interested. Shannon was the ideal buddy: relaxed and really into photography, so we kept the same tempo. It was a very shallow dive (maybe 5 meters), so we were only limited by getting cold, which was after an hour. I chose to use my 60mm lens, but not to use the 1:1 macro setting, but the 0.19-040 focal range to try my hand at slightly larger objects such as fish. I was thus lucky in a sense that I did not encounter any beautiful nudibranchs of which I would not be able to to take a good shot. (Edit: actually, I since learned that 1:1 is still possible using this focal range). It was however unfortunate that I could not get a good shot of a cuttlefish that hovered about two meters away, rapidly changing colour and catching a wrasse! Next time I will perhaps change settings again to try my hand at (cuttle)fish swimming a bit further away. However, I was very happy with sticking to Leopard-spotted gobies Thorogobius ephippiatus. They do not stick their little faces out of nooks as do most blennies, but usually lie on and under ledges. The trick was to approach very slowly, shooting until they swam off. For some reason, I managed to position my strobe right and did not have backscatter issues. I used Windows Photos to postprocess. See below for a before and after example: Two other common organisms below: a Squat lobster Galathea rugosa and a Twin fan worm Bispira volutacornis. And finally an out of focus, but fun photo of a tiny tiny clingfish very aptly clinging to Shannon’s housing. This was one of the most fun dives in ages and I hope to repeat it sometime soon!

Furbellows

One of the nice things about Cornwall is that there are so many coves and beaches, that even after seven years of living here, there are still plenty left to discover. This weekend we visited Kennack Sands on the Lizard peninsula. Two fine sandy beaches separated by a small hill and a rocky outcrop in the sea. What I also like about Cornwall is that every rock has a name. The rocks we explored are called Caerverracks. The tide was pretty good, the weather as well (except for a brief shower). The viz however was quite bad, and so I hope to go back one time when the sea is flat to retake some of these pictures. The rocks did offer some shelter though and it was great to be in the water. I focused (no pun intended) on a type of kelp called Furbellows (Saccorhiza polyschides). It is called that way because of the ruffles on the stipe (in dress-making, furbelow is another word for ruffle). These wavey frills help to dissipate wave energy, which of course can be very intense on Atlantic shores. This seaweed is much more prone to epiphytic groth than the surrounding Laminaria kelp. This must be the reason why it is always covered with grazing Grey topshells Steromphala cineraria. As with other kelps, it is home to the Blue-rayed limpet Patella pelucida. As the conditions were bad, I was forced to limit myself to a large, abundant and non-moving subject, but it was actually quite nice to work within such constraints. One of my favourite seaweeds and when conditions are better (and when I am by myself, with more time and a weight belt so I can dive down instead of holding the camera down and shooting ‘blind’), I definitely want to try again!

St. Michaels Mount

A bit of practice with over under shots two weeks ago when camping near St. Michaels Mount in Marazion. An ancient and beautiful backdrop to a fine sandy beach, with a causeway, rocky outcrops as well as seagrass. I was not alone and did not have much time and importantly no strobe handy, which made the exposure difference between under- and above water tricky. The main problem was however that I could not get up close to the Mount, leaving it quite small in the composition. Still, a great hour in the water. Many two-spot gobies were around and this is a site with lots of egg cases of the Nursehound (or large-spotted dogfish, or greater spotted dogfish or bull huss) Scyliorhinus stellaris.
