beach combing on the Roseland

Back at Carne Beach on the Roseland Peninsula. No time for a good rock pooling session, but a nice walk along the beach revealed some nice surprises. Amongst the Laver and Furbellows lay Common starfish, Pod razorshells, Striped venus, Banded wedge shells and Rayed trough shells. A first: the Masked crab Corystes cassivelaunus (a female): common offshore buried in the sand, and usually only seen when washed up dead on the shore as is the case here (next to it a Sea apple). Also a beautiful piece of Sea beach (or Sea oak? the margins seem not ruffled enough though…). Finally, a Barrel jellyfish Rhizostoma pulmo, remarkably firm and heavy. This is a small one, about 20 cm across; 40 cm is normal and occasionally they grow to more than a meter in diameter, making it the largest jellyfish species in British waters.IMG_6407

Stalked Jellyfish

IMG_5675A trip to Carne Beach on the Roseland Peninsula, east of Porthscato and west of Nare Head. The beach is facing south and the sun was so bright that my iPhone pictures were all overexposed, but I’m not complaining in February! I did not have time to go rock pooling much longer than ten minutes, but in this time, I managed to find Stalked Jellyfish, as described in the previous post. Some very nice rock pools to the east of the beach (the pools to the west where the beach is called Pendower looked even better). On pretty much every Slender wart weed Gracilaria gracilis plant I found a Spotted kaleidoscope jellyfish Haliclystis octoradiatus (see stauromedusae.co.uk for all things stalked jellyfish). I also found a smaller, red species which David Fenwick ID’d as a Lucernariopsis campanulata (last two pictures). I will now keep my eyes out for these beautiful little creatures as their biology and distribution are not well-known and record my findings.
