Erratum

The original version of this article [1] unfortunately contained a mistake. The presentation of Table 1 along with the table legend and footnote was incorrect in the HTML and PDF versions of this article. The corrected version is given below.

Table 1 Positively selected sites in octopus haemocyanin at which at least three or more selection tests identified significant positive selection. Analysis was performed for two separate alignments, containing 113 or 126 sequences respectively, and covering in total a 396 amino acid long region of the haemocyanin’s functional units f and g. Numbering of positions refers to the published full haemocyanin sequence of Enteroctopus dofleini [UniProt: O61363] [23, 24]. Significance thresholds were: P ≤ 0.10 for SLAC, ≤ 0.10 for FEL, MEME and PRIME; Posterior Probability ≥ 0.90 for FUBAR; Bayes Factor ≥ 0.50 for EF. See Additional file 5 for detailed results
