How to spot the Orca when scuba diving
Orcinus orca
Most widely distributed cetacean, found in all oceans worldwide, from Arctic and Antarctic waters to tropical seas. Most abundant in colder, productive waters (e.g., Antarctica, Norway, Alaska, Pacific Northwest). Different ecotypes (resident, transient, offshore) exist with varying ranges and diets.
Encounters often linked to prey migrations. Norway (Troms/Finnmark region) is a major hotspot for snorkeling encounters from late October to mid-January when orcas follow herring migrations. Other locations like Antarctica or specific Pacific Northwest areas have seasonal sightings.
Primarily found in colder waters, but adaptable. Norway encounters occur in winter cold waters.
Specific aggregation areas during certain seasons (e.g., Northern Norway fjords, parts of Antarctica, Pacific Northwest). Encounters are typically surface-based (snorkeling or boat viewing) via permitted operators due to regulations and the nature of the animals. Scuba diving interactions are very rare and usually opportunistic or part of specific expeditions.
