Sertularella areyi is considered as a circumtropical species (Calder 2013). It was reported from the east coast of South Africa by Millard (1975, as Sertularella annulaventricosa Mulder & Trebilcock, 1915), but not from the west coast. Our record from Vema Seamount is the first one in the South Atlantic Ocean. The bathymetric distribution ranges from 47 (Millard 1975, as S. annulaventricosa) to a depth of 480 m (Vervoort 1993).
