The winter season is the time for beachcombing and so I was very happy that Santa gave me The Essential Guide to Beachcombing and the Strandline; a fantastic guide to objects washed on British (and NW European) shores by Steve Trewhella and Julie Hatcher. One of the things that sets it apart from other guides is that it not only covers biological ‘objects’ (shells, fish, mermaid’s purses, sea beans etc) but also strandline debris of human origin (e.g. buoys and nurdles). After a walk at Praa Sands beach, it helped me to identify the Goose barnacle Lepas pectinata. A must-have book for anyone who likes to spend time on the beach! At Praa Sands I also found several Chama bivalves attached to a tangle of rope. David Fenwick has recently described three Chama species, all from (around) Florida (there are no native species), see here for much more detail. Unfortunately it is very difficult to tell what species it is from only the lower valve of the ‘Jewel Box’. It is interesting to see that even commonly encountered bits of rope and net can be from as far as the other side of the ocean. Hopefully there will be some westerly January storms to wash up more interesting species!
The first weekend after the recent storms and a bright blue sky meant that it was time for some beach combing. The beach at Praa Sands looked glorious in the sun, but we were probably a little late for the serious stuff (if there was any to begin with). So no dead Triggerfish, Columbus crabs or suitcases filled with cocaine. Instead, lots of bits of plastic and rope and some Velella remnants and empty Dogfish (or Small-spotted catshark Scyliorhinus canicula) egg cases. Of course also Common goose barnacles Lepas anatifer:
More interesting was a vat with (dead) Devonshire-cup-corals Caryophyllia smithii attached:
Damage to the coast was evident:
