摘要
A new benthic chaetognath, Spadella boucheri sp. nov., is described from Bora Bay, Miyako Island, near Okinawa (Japan). It is presently the smallest known species of the phylum. Its small size and the narrowness of its lateral fins suggest that it could live occasionally between the sand grains of the superficial substrate, a behaviour that had been previously hypothesized for a Spadella from the European waters. The problem of endemism of chaetognaths living in semi-closed bays of islands scattered in the open ocean is discussed.
