In this article the images of Figs. 5 and 6 images were wrongly assigned; the captions are correct, but the image of Fig. 5 belongs to Fig. 6 and vice versa as shown below.

Maximum likelihood phylogenetic tree of Alcyonidium based on 646 unambiguously aligned nucleotide sites of the COI gene. Values on nodes represent posterior probabilities for BI (based on last 75% of trees) and bootstrap support (1000 replicates), respectively. Support values < 50% are not shown. The scale bar represents one substitutional change per 100 nucleotide positions. * Sequence was generated during this study
