Neighbor-joining analysis of mtDNA haplotypes of Scomber japonicus and S. australasicus identified by restric- 
tion site analysis. Branch lengths are indicated. The terminal nodes labeled ATL are Atlantic haplotypes of S. 
japonicus 20-58 from J-FLA, J-ARG, J-SAF, J-IVC, and J-ISR. Haplotypes 1-13 labeled JPN or TWN are S. 
japonicus from J-JPN and J-TWN. Haplotypes 14-9 labeled CAL are S. japonicus from J-CAL. Haplotypes 61-68 
labeled RED are S. australasicus haplotypes from A-RED. Those labeled UN are “unique” haplotypes 69-78 ofS. 
australasicus from A-NZL and A-AUS. Those labeled UB are “ubiquitous” haplotypes 79-93 of S. australasicus 
from A-NZL, A-AUS A-MEX, and A-JPN.
