Figure 1.
Map indicating sampling locations in the Pacific Ocean.
TW = Taiwan, HH = Hawaii, BA = Baja, SC = Southern California, CL = Clipperton Island, CR = Costa Rica, COL = Colombia, ECU = Ecuador. Sample numbers for each location are shown in parentheses.
Figure 2.
Haplotype network obtained from the TCS analysis.
The size of the circle represents the frequency of each haplotype. Numbers represent substitutions between haplotypes and small lines represent hypothetical haplotypes not observed in this study.

Coalescent tree showing reciprocal monophyly between haplotypes from the A and B clades.
Posterior values are shown as branch labels.
