The Medway is one of the first sites it has been recorded in the U.K. It has probably arrived via dredged ballast (the Arco dredgers discharge just a short way upstream of Upnor), and is a species that will oust our native shore crab.

I've been told not all comments are publishing. There seems to be a problem between Blogger and Chrome, and I'm being told if you have a problem you should try a different search engine.
All a pain in the proverbial. Sorry! I'm a luddite/technophobe (still won't even have a mobile phone) so much else is beyond me..
If still doesn't work, pls send me a DM/post to my twitter a/c @dunnokev to let me know- thanks! Kev 18/12/21
