Phylogenetic tree of Osedax based on the concatenated analyses (Gblocked dataset) of COI, 16S, 18S, 28S, and H3 from Bayesian inference analysis (BI).

Squares on nodes refer to support retrieved from 4 different analyses: upper, left gblocked alignment under BI; upper right, complete alignment under BI; bottom left, gblocked alignment under ML; bottom right, complete alignment under ML. Green squares indicate posterior probability values (PP) > 0.95; bootstrap support (BS) > 95, yellow squares indicate 0.90 > PP BS Osedax deceptionensis and O. ‘mediterranea’ are indicated in bold. The six major Osedax clades previously defined by [11] and [12] are highlighted.
