The paper describes the colonies of Sabellaria alveolata that have been recorded at Duckpool 1961-1970. A map indicating where on the shore the various colonies were found is provided but the scale of the map makes it very difficult to estimate the latitude/longitude and/or grid references of the colonies described. A point in the middle of the shore, given in the paper has been used.

Massive colonies several feet across and up to some 2ft thick, mainly of shell particles cemented together by the worms, as well as many smaller colonies and single tubes, here reach their maximum development in south-west England. Sites and colonies were photographed and some measured at frequent intervals over long periods of time. Comparative studies of long series of color transparencies examined closely with a binocular microscope have proved invaluable in elucidating the manner and rate of growth of varied types of colonies, their lengths of life and the manner of their ultimate destruction. This survey was collated by MarLIN as part of a data collation contract for species on the provisional list of Nationally Important Marine Features.
