Late May Seaweeds

A day without wind last Thursday and so time for a look at the seaweeds. As expected, the pinks, reds and purples have made way for browns, yellows and greens. The water was a bit cloudy but with the wide angle lens you can get close up minimising the effetc of the bad viz. Wrasse were tending to nests and tiny pollock swam around but otherwise I could not spot not many animals; the exception was a big spider crab who was as startled as me. Above the common species Thin Sausage Weed Asperococcus fistulosus. Not the most beautiful species but let’s say it looks interesting. To my horror, I discovered that my favourite seaweed Bushy Rainbow Wrack has changed genus and is now called Carpodesmia tamariscifolia instead of Cystoseira tamariscifolia. I hate name changes in general but this just an ugly name! Two photos of this species below as well as one of Bushy Berry Wrack Cystoseira baccata which also has moved genus and is now Treptacantha baccata… After that a floating piece of Desmarest’s Flattened Weed Desmarestia ligulata and some Pale Patch Laver Pyropia leucostica.

Seaweed Gallery

Some long overdue seaweed pics from the end of the seaweed bloom when the tides were low. I took many photos but few, if any, very good ones; sometimes you just are a bit out of luck I suppose. I have also started a Seaweed Gallery page (link also pinned at the top), gathering photos of as many different species I can find here in Cornwall. It is very much a work in progress and not a proper guide at all, but I hope it can help complement exisiting guides. Note that just a photo often is not enough to correctly identify species, so I have kept it at more easily recognisable things. On another note, I recently gave a ‘lockdown’ zoom presentation about my very niche hobby of taking photos of seaweeds for the Cornwall Wildlife Trust. If you are interested you can find it on youtube (I have not watched it back myself as if there is one thing I dislike it is seeing myself talk on video (actually, there is one thing I like even less and that is seeing myself talk on a video that is there to see for the whole world!)). I talked not so much about photography or seaweed biology as I am far from an expert in either topic, but more about how I started out with rockpooling when I moved to Cornwall in 2012, and how this slowly spiralled out of control and ended up with me lying facedown in rockpools year-round taking photos of seaweeds. Anyway, a few species below: Irish Moss Chondrus crispus, Berry Wart Cress Sphaerococcus coronopifolius, Red Rags Dilsea carnosa and Desmarest’s Flattened Weed Desmarestia ligulata.
