The Barnacles Synopsis updates Bassindale’s classic work on British Barnacles, published in 1966, and Rainbow (1984).

Barnacles are familiar objects to mariners and seaside tourists. They extend from the high water splash zone to the depths of the ocean and can also live close to hydrothermal vents.

It is the first Synopsis to include colour plates in addition to line drawings, Since skin lining the opercular plates (the tergo-scutal flaps) is distinctively coloured, it is a very helpful aid to identification. Coverage of the seas surrounding the British Isles extends to a depth of 200 metres.
