Some Silver Steps Molluscs

Posted on by under diving, molluscs, shells, Silver Steps
After posting about the fish and crustaceans of my local dive site Silver Steps in Falmouth, it is time to give molluscs some love! The photos in this post were all taken at 5-10 meter depth at a gravelly bottom this year. Above (and at the end) the Turban Topshell (Gibbula magus) which is common subtidally. However, this was the first time I noticed that they have pretty sky-blue eyes! It is one of my challenges to take a pic of it with both eyes in the frame next year. Below, another favourite species of mine: the Pheasant Shell (Tricolia picta, previously P. pullus). This was a large individual (close to a centimetre?) with a candy cane striped pattern that I’d never seen before.
Next up a juvenile European Stingwinkle (Ocenebra erinaceus) on top of a Saddle Oyster and the Common Keyhole Limpet (Diodora graeca). The latter might be called ‘common’ but I do not see it very often. Going from the Gastropods to the Bivalves: a King Scallop (Pecten maximus) with its many eyes. Moving to yet another Mollusc Class: meet the Cephalopod Common Cuttlefish (Sepia officinalis). This was a very large individual covered in many small white lesions, probably near the end of its life. It was fine in my presence and let me take some photos. It is sometimes strange to think that these intelligent creatures are more closely related to a clam than to a fish! Some bonus photos at the end.

The Crack pt. 1

Posted on by under crustaceans, diving, EMWL, fish, Silver Steps
At my local shoredive site Silver Steps here in Falmouth, there is a crack in the rocks, maybe three meters long and not very deep, that is home to an array of interesting species. I have posted pics from this spot before, for instance that of a big conger eel (which has since left it’s hidey-hole, perhaps it swam off to reproduce and die in the Mid-Atlantic?). Anyway, I visited again this week and tried close-up shots with my macrowide angle probe lens. The prawns are much bigger here in the rock pools, but I am not sure if they are Paleamon serratus or P. elegans, as this requires a closer look at the serrations on the rostrum. Regardless of species name, they are stunningly beautiful animals with their blue and yellow legs and black-striped carapace.

Some more pics below (notice that in some another animal is lurking in the background!). Some species are easier to photograph than others, clingfish are very shy for instance. Anyway, there are some more ideas I have, for instance trying to capture multiple species in one frame and post about them in ‘The Crack pt2.’!

Back to Silver Steps

Posted on by under diving, fish, Macro, molluscs, nudibranchs, Silver Steps, worms

With the camera housing back, I have been in the water again lately, taking quite a few photos. I am lagging behind with posting quite a bit (this will allow me to post when I cannot get in the water later in the year) but should occasionally maintain the blog over summer, so here is! My local haunt Silver Steps provided during two dives with the macro lens. Above a Twin Fan Worm (Bispira volutacornis). These are quite shy (i.e. they retract into their parchment-like tube when their composite eyes detect a curious diver) but also are attached to cluttered rock walls. To blur this unappealing background, I used a very shallow depth of field (f 2.8); this also has the advantage of letting a lot of light in so ISO can be decreased to 100 – sorry non-photographers!). Below a collage of other ‘usual suspects’ (names under the photos) but ALSO I SPOTTED AN OCTOPUS! Crouched in a crevice and with only a macro lens I could not do it justice but it was still a very nice encounter.

Fish of Silver Steps

Posted on by under diving, EMWL, fish, Silver Steps
It is almost February so it is high time for the first 2025 post! I have quite some photos left from last year and I thought a fish photo-dump might be a nice idea. My local shoredive site ‘Silver Steps’ has quite a diversity of fish; however, I have only ever seriously tried to photograph benthic species as the pelagic swimmers are just to difficult to capture, even just for ID purposes. A shame, as I have seen some interesting Seabream species last year (Gilthead Seabream, schools of juveniles that might be Axillary, or Red Seabream and even a Common Two-Banded Seabream) and the wrasse species are very characterful (and I have seen others take great photos of them). Anyway, first up is a Conger Eel (Conger conger) I often visit. Quite menacing, although probably not as big as it looks. I always find it in its lair, probably only coming out at night to hunt (having said that occasionally I do see free-swimming congers during the day). It is always surrounded by big prawns who do not seem to be on the menu somehow, but must be protected from other predators this way.

Below photos of various smaller fish hiding in the rock cracks (click for names on the pictures).

Finally a favourite of mine: the Topknot (Zeugopterus punctatus). Not quite nailed the shot yet – maybe this year!

Scorpion Spider Crabs

Posted on by under anemones, crustaceans, diving, EMWL, photography, Silver Steps
I recently posted on the Crustaceans inhabiting my local shore dive site Silver Steps (see here), but left out one species: the Scorpion Spider Crab (Inachus spp.), which deserves a post on its own. I have blogged about this crab before (see here), specifically in the context of ‘macro-wide angle’ for which this species, perched on- or under a snakelocks anemone, is ideally suited. My previous efforts were based on an affordable inon wetlens, but I have since bought a super-duper nauticam lens. Although very good at macro-wide angle, this lens lets in very little light, which basically gives you three options: 1) lie on some bright white coral sand in the Maldives and shoot upwards to the sun at midday (so actually not really an option), 2) increasingly compromise the exposure triangle to keep a blueish/greenish background (higher ISO>more noise, lower shutterspeed>more camera shake, greater aperture>smaller depth of field), or 3) keep all settings in a ‘normal’ range, resulting in a foreground lit up by strobes on maximum output, but a black background (only if you are shooting critters in rock crevices you can get both fore- and background well-exposed, as strobe light has something to bounce back from – see for some examples the Crustaceans post). I quite like the clean black background and dislike bluer, but grainier images, so have mainly tried option 3. Hopefully, next year in summer I can try going for some blue background shots. Sorry if this blog is occasionally turning into a photography borefest by the way, but I have been really getting into that stuff! ;-). Anyway, these scorpion spider crab pics have turned out quite nicely.

Crustacean Crevice Dwellers

Posted on by under crustaceans, diving, Silver Steps

I have done a fair bit of diving at Silver Steps this year and it is high time to publish some of the photos I took there, starting with the Crustaceans that inhabit the cracks in the rocks. Most pics were taken with the macro-wide angle lens, which is not only suited because of its perspective, but also because it is long and thin and so can be poked into the crevices where these creatures lurk. Above, two Velvet Crabs Necora puber, which are abundant and feisty – I only noticed the small female in the photo afterwards! Below a European Lobster Homarus gammarus, also quite common and some of them are quite big. They usually shuffle out of their den quite menacingly only then to retreat again. Although impressive animals, it is hard to get an aesthetically pleasing shot out of them I find.

Next, the Squat Lobster Galathea strigosa, also a common, but quite shy species which is just as happy upside down as right side up. Also common are Brown (or Edible) Crabs Cancer pagurus, the individual here not in a crevice but in a piece of steel wreckage.

The other big, common Crustacean here occasionally perches on rock walls but usually is found roaming the seabed: the European Spider Crab (rebranded by local fishmongers as ‘Cornish King Crab’ – sounds more appetizing than something spiderlike) Maja squinado brachydactyla. Like the lobster, the behaviour of these guys is a mixture of bravado and fear. The weird lens allows me to get close, but as it lets in very little light, I am forced to use a high ISO and slow shutterspeed, making these images not the crispiest.

The final photo is technically not great, but I like it because it shows how a range of species apparently gets on quite well at close quarters. On the left, a Common Prawn Palaemon serratus, which can grow quite large and is actually really beautiful with its blue and yellow stripes. Right behind it is a Squat Lobster, with two Edible Crabs lurking in the background and an upside down male Connemara Clingfish Lepadogaster candolii – the next post will be about the fish of Silver Steps!

Kennack Sands Shoredive

Posted on by under cnidarians, coral, diving, Macro

It was a glorious day last Sunday so time to get outdoors. After a pitstop at Windmill Farm (see here), we sat down at Kennack Sands Beach. I brought my scuba kit as I wanted to have a little looksee under water. I could not find any (shore)diving reports on this location, but I had snorkeled here a few times before and it looked interesting, a serpentine reef parting the beach in two. The tide was high and there was a bit of a swell so it took some swimming out – even so I never got any deeper than seven meters. I was a bit disappointed at first: the sands were shifting and there was no chance of finding interesting flatfish or molluscs there, the rocks has furbelows kelp on them but otherwise nothing too special. I then found a slightly deeper gully and took a closer look at the rocks and found loads of interesting little things, even two tiny dead man’s fingers soft coral!

Black-faced Blennies

Posted on by under diving, EMWL, fish, Macro, Silver Steps

Dear reader, it has been a while! With the weather taking a turn for the worse, I thought it would be high time to start updating the blog again. I have taken more photos this year than ever before, and actually have dived my local shore site “Silver Steps” in Falmouth ‘to death’, so now have plenty of material. I’d thought I start with a post on one of my favourite fish, the Black-faced Blenny (Tripterygion delaisi). This is a beautiful little fish (a triple-fin blenny, not a ‘true’ blenny) that lives under rock overhangs, usually perched upside down. Breeding males are bright yellow with a black head and an electric blue edged dorsal fin, while females and males outside of the breeding season have a mottled brown-white coloration (which is equally beautiful testified by the pic on the top right). These fish (especially the females) are skittish and also require a bit of contortion to photograph under the overhangs but it is more than worth it! Below a photo-dump of fish shots taken with my 60mm macro lens and a combination of that lens and a superduper macro-wide-angle wetlens (details of which I am bound to bore you with in coming posts!).

2024 so far…

Posted on by under diving, fish, Helford

Above some pics of a recent, impromptu snorkel in the Helford; a catshark, a cuttlefish and a greater pipefish which I could snap with the fisheye lens while battling a raging tidal current. I have dived a lot recently, did my PADI advanced open water (to make it easier to participate in some deeper diving in the future ), finally dived Porthkerris, bought a fancy new wetlens and stepped up my iNaturalist game. I took some good photos as well, but for many of these I reckon I could replace them with an even better version. For this reason, and also because there will be plenty of rainy days at the end of the year to blog instead of dive, I will probably remain a bit quiet here for now, add to the collection of photos, and update the blog a lot more later! (P.S. I do post from time to time on instagram: @an_bollenessor.)
