Orca

Orcinus orca

Also known as Killer Whale, Blackfish, Grampus

Orcas are highly social apex predators that travel in matrilineal pods, utilizing complex vocal dialects and coordinated strategies to hunt everything from salmon to blue whales. Different distinct ecotypes specialize in specific prey and hunting techniques, ranging from beach-ing themselves to catch seals to wave-washing ice floes. Matriarchs lead these family units for decades, passing down intricate cultural knowledge to younger generations.

Why interaction risk is high
Apex marine predator capable of severe harm; maintain a respectful distance at all times.
Why it is dangerous
Extremely large apex predators capable of flipping small watercraft or causing trauma if stressed.
How to recognize a risky encounter
Distinct black-and-white body with a tall triangular dorsal fin and white eye patches.
What to do
Never enter the water near wild pods; give them a wide berth and keep boat engines in neutral.
What to notice
Tall dorsal fin breaching the surface accompanied by loud, explosive exhales.
Support conservation
Reduce speed below 7 knots when near pods and never cut across their direction of travel.
Responsible observation
  • Observe from Boats: Keep engine in neutral or idle when whales approach within 300 meters.
  • Watch for Blows: Look for tall vertical spouts rising 3 meters high on calm seas.
  • Respect Regulations: Maintain minimum legal distances to protect pod communication and hunting.
