The most commonly spotted orca species off the Pacific Coast is the Resident orca.

Resident orcas are a subpopulation of orcas that are frequently seen in the Pacific Ocean, particularly around Washington, British Columbia, and Alaska. They are known for their strong attachment to specific areas, often found in coastal waters where they primarily feed on fish, especially salmon. These orcas live in tight-knit family groups, or pods, and have a culture centered around communication, hunting strategies, and traditions passed down through generations. Unlike transient or offshore orcas, resident orcas stay in one region year-round, making them the most commonly observed in these areas.
