More Macro

Posted on by under eggs, Macro, molluscs, nudibranchs

Has ‘an bollenessor’ turned into a macro photography-only blog? It seems so, I have not posted about my aquarium in ages. I still end up doing macrophotography when I go rockpooling. I tried wide-angle photography last week in the rockpools and failed miserably (so no photos for the blog). I hope to mix it up later in the year but for the moment here are some more macro photos. Above a picture I am quite pleased with: a solar-powered seaslug Elysia viridis on its favourite food the green seaweed Codium with some nice orange seaweed as a background. The pictures below show the snail Raphitoma purpurea (a first for me in Cornwall), the nudibranch Okenia nodosa (a lifer for me), a European Cowrie Trivia monacha and a patch of goby eggs (sans goby-egg eating seaslugs unfortunately).

I am a bit stuck in a limbo where on one hand I want to see interesting, new species and take good ID pictures (for recording on iNaturalist and sharing on facebook groups), but on the other hand I have gone a bit above my station and developed an interest in taking more ‘arty’ photos such as the solar-powered seaslug one at the top of this post. Sometimes the two aims converge. sometimes not. As an illustration of that, below a few shots of the nudibranch Polycera quadrilineata that ended up quite differently: a ‘good for ID’ photo but with an ugly cluttered background, a more arty photo (although the bokeh effect is due to backscatter and it is actually not that great), an overall ‘nice’ photo (posted before), a ‘shore studio’ shot of a slug (more about that in the next post) and an artsy fartsy version of a studio shot where the highlight have been so blown out that the slug basically is shown as a set of yellow stripes. I must say I can have ideas about how to take a certain shot, but my general approach is still ‘spray and pray’!

Periwinkles

Posted on by 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…
