Figure 3. The fragment of the interleaved amino acid sequence matrix that contains the Leray site of P. lividus species. The horizontal lines indicate site boundaries. The numbers above the matrix indicate the positions of the sites in the complete amino acid sequence of the complete COI gene relative to Phyllophorus liuwutiensis species. For the purpose of comparison, five more representatives of Echinodermata were added to the matrix in addition to this species. The shaded area highlights the deletion sites in P. lividus.
