Figure 3. Phylogenetic tree (neighbour-joining, Kimura two-parameter) showing the genetic divergence between sequences of the control region of the Atlantic (ES, Espírito Santo State; RJ, Rio de Janeiro State; SC, Santa Catarina State; RS, Rio Grande do Sul State) and other regions analysed (Pacific and Indian Oceans). Numbers at nodes correspond to bootstrap values>75% (10 000 replicates). CS Pac, central southern Pacific; ET Pac, eastern tropical Pacific; NW Pac, northwestern Pacific; CE, Ceará State; Sb, Steno bredanensis. MQ and BG are field codes for samples from RJ. The scale bar shows the length of branch that corresponds to a Kimura two-parameter distance of 0.005.
