Tompot Blenny

Every time I dive at my local site Silver Steps, I check out a crack in the rocks that houses a variety of Crustaceans and fish (see for instance this old post). Yesterday I brought my fancy macro-wide angle probe lens specifically to look for a Tompot Blenny (Parablennius gattorugine). I found two, including this male guarding his eggs (visible at the back, top and bottom of the crack in the photo below). The last photo shows that these guys are pretty feisty too!

More Macro

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’!

mystery eggs

I saw a couple of these egg clusters some time ago and asked my friends at the British Marine Life Study Society Facebook page what they could be. Unfortunately I have not had any suggestions yet. Do you know who laid these eggs?

Aha, Bert Roos from the Dutch ‘Noordzee en Koud Zeewater Forum’ reckons these are eggs laid by the Long-spined Bullhead Taurulus bubalis!
