摘要

This study is the first report on the successful application of the DAPI (4',6-diamidino-2-phenylindole) staining technique to 22 families of five of the six radiolarian orders (Acantharia, Collodaria, Nassellaria, Spumellaria, and Taxopodia, excluding Entactinaria). A total of six Acan-tharian species, three Collodarian species, three Spumellarian species, 18 Nassellarian species, and one Taxopod species emitted blue light under epifluorescence microscopy after DAPI staining. These results and existing data indicated that Acantharia and two collodarian families (Col-losphaeridae and Sphaerozoidae) are multi-nucleated, whereas Nassellaria, Spumellaria, Taxopodia, and Thalassosphaeridae form a single-nucleus group. The shape, location, and number of nuclei in Radiolaria were variable not only at the family level but also at lower taxonomic levels. Even within species such as Spirocyrtis scalaris, nuclei can move from the cephalis to intracapsu-lum lobes below the cephalis.
