Non-Migrant: No. All populations of this species make significant seasonal migrations.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.
Migrates between nearshore waters (summer) deeper waters (winter) (Castro 1983). Female groups make coordinated seasonal coastal movements possibly for breeding, gestation, and eventually parturition (Gilmore et al. 1983).
