An Orca whale diving while displaying his tail fluke in Johnstone Strait, around Northern Vancouver Island in British Columbia, Canada.

An Orca whale shows off his tail fluke as he plays with some kelp in the waters of Johnstone Strait in British Columbia, Canada. Orcas love to roll and twist the kelp around their fluke and fins.

The fluke of an Orca is used for a variety of different purposes such as swimming, playing and showing aggressive behaviour. If you listen when a orca slaps its tail on the oceans' surface you understand the power associated with their flukes.

On whale watching tours that depart from Port McNeill on Northern Vancouver Island in British Columbia, you can witness for yourself this powerful yet amazing sight of the fluke of an Orca.
