Species information - Populations in the NE Pacific Ocean:

This page is often used by the students from coastal British Columbia to do marine mammal research projects which is why it is specified when the pages do not relate to local populations.
Best resource for BC species is Dr. John Ford’s Marine Mammals of British Columbia (Royal BC Museum Handbook).
