About 300 orcas live in two "resident"
communities in the waters of North America's Pacific Northwest region.
Vancouver Island lies in the centre of the region. A "northern" resident
community uses the waters off northern Vancouver Island and the central
coast of British Columbia; and a "southern" resident community uses
the waters off southern Vancouver Island and Washington State. A "transient"
community of more than 200 individuals also uses these waters. A little
understood "Offshore" community of several hundred orcas occupies
waters further from the coast. Studies of orcas in the wild have been
conducted in the ocean around Vancouver Island longer than anywhere
