|Taxonomic Notes:||No subspecies are recognized. Phylogenetic
analyses reveal that populations in different ocean basins do
not represent distinct clades, but some maternal lineages can be
traced back across hemispheric boundaries, indicating some level
of inter-hemispheric gene flow, perhaps in the distant past
(Baker et al. 1994).| |Red List Category & Criteria:||Least

(Cetacean Red List Authority)| Although no final assessment of
the current global population relative to its 1940 level is
available, it seems, based on the recent rates of increase,
unlikely that it is below the threshold (50% of the 1940 level)
that would qualify the species for inclus
