Figure 2.
The 50% majority rule consensus tree from the Bayesian analysis of the combined dataset (18S rDNA and 28S rDNA). The tree is rooted on the Stenetriidae. The numbers represent Bayesian posterior probabilities (a, 1.00–0.95; b, 0.94–0.85; c, 0.84–0.75; d, 0.74–0.65; e, 0.64–0.50). Species families are indicated by bold bars. The blue taxon names and branches indicate eye-bearing shallow-water species and their putative ancestral lineages, and the black taxon names and branches represent blind deep-sea species.
