The complete nucleotide sequence of the small ribosomal subunit RNA of the gastropod, Limicolaria kambeul , was determined and used to infer a secondary structure model. In order to clarify the phylogenetic position of the Mollusca among the Metazoa, an evolutionary tree was constructed by neighbor‐joining, starting from an alignment of small ribosomal subunit RNA sequences. The Mollusca appear to be a monophyletic group, related to Arthropoda and Chordata in an unresolved trichotomy.
