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!
After the success of last weeks snorkelling session, it was high time for a proper dive! Again the Helford did not disappoint. In the end, my Sea hare stroking proved a bit inconclusive; also, my estimate of 30 cm long individuals might have been a slight exaggeration, 20-25 cm is more likely for the larger individuals. My guess is that it might be Aplysia punctata after all, and perhaps this is just a very good year where they reach their maximum size. (Note that three individuals can be seen in the first photo and two in the second photo.)This was not the only Ophistobranch activity going on, as I spotted a small nudibranch sitting on the eelgrass. Probably Eubranchus farrani, although it could well be something that is deserving of a new name, there is a lot of (cryptic) species discovery and taxonomic revision ongoing in nudibranch biology. I also spotted several largish egg masses on the eelgrass that are likely to be from a larger, shelled Ophistobranch; I am waiting for suggestions from various facebook groups *could be Haminoea navicula*. I found a beautiful Wooden canoe bubble shell Scaphander lignarius, these animals live buried in the sand so are not commonly spotted. Next time I’ll bring a small garden rake to see what is hidden below the sand (I am serious!), lots of echinoderms and molluscs to be sure. Pelican’s foot shells Aporrhais pespelecani live in sand, but I found some on top of the sand too, so full of muck that they were barely recognizable. I have found empty shells of this species washed up on holidays before, but it was cool to see them alive for the first time.No cuttlefish in sight this time, but loads of eggs so it is likely that this is an important breeding ground for this species. We encountered one Thornback ray Raya clavata, which, like cuttlefish, are not very shy. These species occur in very shallow waters (we probably did not dive deeper than 7 meter) and the influence of the surrounding woodland is clear, with decaying oak leaves and pine cones amidst the seaweeds and eelgrass.One very well-camouflaged species is the Scorpion spider crab Inachus dorsettensis. Medium-sized Common hermit crabs Pagurus bernhardus are common, running around in Turban top shells covered with hydroids. Although present in the last post, another pic of a
Mud sagartia Sagartia troglodytes anemone Red speckled anemone Anthopleuris ballii. Filterfeeding worms are abundant too, including the beautiful Fan worm Myxicola infundibulum as well as a large tube-dwelling worm and worms in white calcareous tubes with bright red bristles that I could not identify. As we got out of the water, we saw a Comb jelly Beroe cucumis, very pretty but hard to photograph. The next dive will have to wait two weeks or so, but then I hope to finally play around with my GoPro.
