Goose barnacles

I thought you might like to know more about why this has been identified as D. fascicularis. There are 7 species of goose barnacles (Lepadidae) in the British fauna. The one most commonly called ‘goose barnacle’ is Lepas anatifera which has the longest ‘stalk’ (at least 4cm and upto 8.5cm). http://www.ispot.org.uk/node/320247

This one, Dosima fascicularis, aka buoy barnacle, is distinguished by the shorter ‘stalk’, the more angled and thus flatter base and the float that it often secretes (which looks a bit like expanded polystyrene). It is from warmer climes but is often stranded on the south and west coasts of British Isles.
