Portuguese Man O’ War

It is that time of the year again: gales, rain and darkness. The only good thing about late autumn/winter to me is that the wind blows interesting things on the beach. Portuguese Men o’ War (Physalia physalis) have been a common sight the last few years (see this post from 2017), perhaps more so than it used to be, but not sure this has been properly investigated. Yesterday we saw several dozen at Loe Bar near Helston, including the smallest specimen I have seen so far. No By-the-Wind-Sailors Vellella and no Violet Snails Janthina, and definitely no Porpita or Glaucus; maybe someday!

The Essential Guide to Beachcombing and the Strandline

IMG_1325The 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!IMG_1450IMG_1344IMG_1332IMG_1334IMG_1336
