Back to Silver Steps

Posted on August 19, 2025 by An Bollenessor 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.

Periwinkles

Posted on July 6, 2025 by An Bollenessor under Macro, molluscs

Long time no post – the idea was to spend time taking photos during spring and summer and enjoy the underwater world vicariously by blogging in autumn and winter. However, something terrible happened on my only dive of 2025: my underwater housing sprung a leak! The housing was not flooded to an extent that it damaged my camera but it needed to be repaired before I could get back underwater. Unfortunately there is only one place that can do that, backscatter all the way in California, and even more unfortunately, U.S. customs decided to keep my package on a shelf for over a month. I have never seen an octopus in my decade of diving but of course people reported eight or so per dive last month so I was feeling very sorry for myself!* Anyway, I have been confined to the shoreline so far. To cope with that, I bought a weird chinese macro-wide angle lens to play with which I will post about later. I also used my ‘normal’ 60mm macro lens (sometimes with a Raynox lens attached to the front for extra magnification) and took some time to focus on periwinkles.

At the top and below a Flat Periwinkle (Littorina obtusata or maybe L. fabialis – distinguishing is very hard as it requires investigating differences in penis shape!). As you can see the locations are not always glamorous, but if you zoom in you can still find beauty!

Flat periwinkles tend to be most active above-water, followed by the smaller Rough Periwinkle (Littorina saxatilis – below) with the Common Periwinkle (Littorina littorea – below that) only occasionally moving about.

Finally, a tiny species the Small Periwinkle (~~Littorina~~ Melharaphe neritoides). Probably overlooked by most, as it is tiny (up to 8mm, usually smaller) and hidden between barnacles (or even nestled in empty barnacle cases) high on the shore.

* and no, I could not bring myself to go diving without a camera…

A Gray Seaslug

Posted on March 18, 2025 by An Bollenessor under Macro, molluscs, nudibranchs, snorkeling

There have been a few finds lately at my local spot in Falmouth (and in other places in Cornwall) of the fantastically coloured Rainbow Slug Babakina anadoni. I have tried in vain so far to find it, but I did manage to find another species of Seaslug last Friday: Aeolidia filomenae. It is the opposite of the Rainbow Slug; large, not small, drab, not extravagant, and common instead of rare. More of an understated beauty I guess, and still a nice find! This species feeds on anemones (mainly Beadlet Anemones but also Snakelocks Anemones) rather than the Candelabrum hydroids the Rainbow Slug prefers. I am not very good at spottting nudibranchs so the plan is to keep looking this spring and find more species!

Two Fish in Flushing

Posted on March 11, 2025 by An Bollenessor under eggs, fish, Flushing, rock pooling

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!)

Rockpools from the top

Posted on February 8, 2025 by An Bollenessor under Flushing, molluscs, nudibranchs, rock pooling, seaweeds

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.

Fish Portraits

Posted on February 7, 2025 by An Bollenessor under fish, Flushing, Macro, rock pooling

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).

Fish of Silver Steps

Posted on January 25, 2025 by An Bollenessor 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!

beachcombing after storm Darragh

Posted on December 10, 2024 by An Bollenessor under beach combing, crustaceans, eggs, fish, iPhone, jellies, molluscs

Storm Darragh raged over the UK last weekend – which by itself was not great, apart from the fact that there was a chance interesting stuff had washed up on the beach! As the winds came from the North, we drove to the long beach at Perranporth on the north coast to have a look. It was nice to get sandblasted for a bit and admire the furious crashing waves and icy blue-grey sea. Find of the day was a dead Grey Triggerfish (*Balistes capriscus*), a generally more southern species that is increasingly observed in the UK. Some other finds in the gallery below (shot with an iPhone; which is actually a lot easier than changing a wide angle for a macro lens on a wet, sandy beach!). Among the finds, Goose Barnacles, a Small-Spotted Catshark eggcase, an unidentified blob and a cuttlefishbone of the Pink Cuttlefish (*Rhombosepion orbignyanum*).

Green Paddleworms

Posted on December 7, 2024 by An Bollenessor under Macro, worms

The Emerald Green Paddle Worm (or Green Leaf Worm) Eulalia clavigera ranges from a few to 10 centimetres and is common in rockpools in Britain (although most are probably more familiar with their egg masses, see here). During a recent scramble over the Trefusis Headland I noticed some out of the water on Codium adhaerens seaweed. Using my cygnustech diffuser and a bit of extra magnification courtesy of a Raynox clip-on macrolens I got to work! Taking photos of these worms is difficult as they are continuously on the move. It is also hard to get close to them with the diffuser bumping into the rocks and obscuring the light. However, they are very rewarding subjects; worms are usually overlooked but they are very beautiful! The Codium seaweed proved a perfect background, absorbing all light, a bit like black velvet. When you spend enough time on your knees peering down, you also always notice other things, some tiny springtails Anura maritima as well as some even tinier red mites (see also this old post). One of my new year’s resolutions is to photograph more worms – and the good thing is that there are many other species available, including paddle worm species, one of which is in the process of being described new to science by my friend David Fenwick).
