photographing seaweeds with a Canon Powershot part III

IMG_2791Another couple of sessions trying to take seaweed photo’s. A couple of seaweed species are really thriving at the moment, one is False eyelash weed Calliblepharis jubata in the middle of the picture above. In the picture below a couple of other species, Irish moss Chondrus crispus in the foreground, Discoid forkweed Polyides rotundus on the left, Black scourweed Ahnfeltia plicata on the right, with some Red grape weed Gastroclonium ovatum at the top. Below that two ‘miscellanious’ pictures and after that some photos of individual species: the photo that turned out best was of Bonnemaison’s hook weed Bonnemaisonia hamifera, an invasive species from the Pacific. After that Juicy whorl weed Chylocladia verticilliata, a Plocamium species and my favourite, the Bushy rainbow wrack Cystoseira tamariscifolia.IMG_3062IMG_2975IMG_3125IMG_2767IMG_3171IMG_3065IMG_3381

 

 

More Scummy Pools

As in Falmouth, the rock pools in Flushing are not looking that great at the moment. Lots of the Corallina has turned white/died (although the clumps in my tank are still their normal purple!). Of course, many species were still thriving, Grape pip weed Mastocarpus stellatus (top), Bunny ears Lomentaria articulata (bottom), new Thong weed Himanthalia elongata ‘buttons’ and a young blade of kelp along with some green Ulva:IMG_0977Among the seaweeds that were thriving was Slimy whip weed Chordaria flagelliformis (I am by no means a seaweed expert and I might be wrong about this, please comment if I am!) and also the beautiful Harpoon weed Asparagospis armata growing as an epiphyte on some darker coloured False eyelash weed. Harpoon weed is invasive and so a good candidate to do well int he aquarium (as most invasive species are quite opportunistic and not too finnicky). It died off in the tank before, but I decided to bring some home to try again now I have a chiller.IMG_0964

IMG_0970Another tangling invasive species: Bonnemaison’s hook weed Bonnemaisonia hamifera (a characteristic curved hook can be seen in the top-middle):IMG_1020Loads more seaweeds to be found but I will save those for another time. All kinds of tunicates pop up in spring, some of them pretty (see for instance here), some of them less so. For instance the invasive species, the Leathery sea squirt Styela clava and an out-of-focus photo of a second, large (>10 cm) species that did not get a lot of response on the NE Atlantic Tunicata FaceBook group. Aplidium nordmanni was offered, see here for a much smaller version of that species. Not a looker either in any case!IMG_1055

IMG_1030I brought my little aquarium net and found many juvenile (<1 cm) fish as well as Mysis shrimp. The fish look like gobies but it is hard to see. They were completely translucent and so you can see what this one just ate. I should take some bits of seaweed home to see what comes crawling and swimming out under a little USB microscope (quite easy to make little videos). It is hard to come up with decent images squatting and squinting on a slippery rock with a salt-encrusted mobile phone!
