A series of 452 samples collected from November 1964 through February 1966 from a North Carolina sandy beach contained 27,219 invertebrates representing 41 species. The sandy-beach community, as composed of a homogeneous group of organisms, was identified through the use of an index of faunal affinity. Community structure is described in terms of abundance, frequency diversity, and feeding types. Six species,Neohaustorius schmitzi, Acanthohaustorius millsi, Donax variabilis, Scolelepis squamata, Exosphaeroma diminutum, andHaploscoloplos fragilis comprise 97% of the fauna by number. Niche differences among these species are discussed.
