Description:
<jats:p>Divergence in cytochrome c oxidase 1 (COI), the genetic marker proposed for DNA barcoding, was investigated in marine bivalves from the genera <jats:italic>Ennucula</jats:italic>, <jats:italic>Nucula</jats:italic>, <jats:italic>Yoldiella</jats:italic> and <jats:italic>Thyasira</jats:italic>. No overlap in levels of intra‐ and interspecific variation was found. The levels of divergence found suggest that barcodes from COI will be useful in distinguishing between the species investigated in this study. The insufficiency of <jats:sc>blast</jats:sc> searches in GenBank to assign many of the obtained sequences to correct phylum was noted and clearly demonstrates the need for better search strategies specifically targeted at identification using DNA barcodes.</jats:p>
