An unusually high abundance and diversity of the Terebridae (Gastropoda: Conoidea) was found at a sampling site in Nha Trang Bay, southern Vietnam. At a single site at depths of 8-20 m, 328 specimens of terebrids, representing 23 species and 8 genera, were collected. Analyses of the species composition, species accumulation curve, and faunal comparison of the Terebridae at Nha Trang Bay and in Vietnam in general with other local Indo-Pacific faunas were carried out. The Vietnamese terebrid fauna appears to be one of the richest in the Indo-Pacific, and at shallow depths, is excelled only by the well-studied fauna of Japan. The most abundant species of the Terebridae in Nha Trang Bay were radular-less. Evolutionary trends in terebrid feeding are discussed.
