The Lives of Orcas (Killer Whales)
Orcas (Orcinus orca), also known as killer whales, are among the most intelligent and social marine mammals on Earth. Recognizable by their striking black-and-white pattern and towering dorsal fins, these apex predators inhabit oceans around the globe, from the icy waters of the Arctic to the temperate fjords of Alaska.
We often see orcas on our photo tours in Alaska’s Kenai Peninsula and Inside Passage, where pods travel through pristine channels in search of salmon, herring, and even larger prey. Observing their communication, coordinated hunting, and playful surface behaviors offers a fascinating glimpse into the complexity of their world.
Moments like these define Alaska’s wilderness, where orcas move silently through fjords framed by snow-covered peaks.

Nine Fun Facts About Orcas (Killer Whales)
Apex Predators: Orcas are at the top of the ocean food chain. They have no natural predators and are known to hunt everything from fish and squid to seals and even large whales.
Not True Whales: Despite their name, orcas are actually the largest members of the dolphin family (Delphinidae).
Distinct Populations: There are different types of orcas, including resident, transient (Bigg’s), and offshore populations. Each has unique behaviors, social structures, and diets.
Highly Social: Orcas live in close-knit family groups called pods. These pods are matriarchal, meaning the oldest female leads them.
Complex Communication: Orcas use a series of clicks, whistles, and pulsed calls to communicate. Each pod has its own unique “dialect.”
Global Range: Orcas are found in every ocean, from tropical seas to polar regions, though they’re most common in cooler waters rich in marine life.
Powerful Hunters: They often work together to herd fish, create waves to wash seals off ice, or coordinate ambushes on larger prey. Their teamwork makes them one of the ocean’s most effective predators.
Incredible Speed: Orcas can reach speeds up to 34 miles per hour, using their strong tails (flukes) to propel through the water.
Long Lifespans: Females can live up to 80–90 years, while males typically live around 50–60 years. This longevity supports their complex social bonds and knowledge passed through generations.
Where We See Orcas on Our Tours
Alaska’s Kenai Peninsula and Inside Passage is one of the best places in North America to photograph orcas. Traveling by boat and private yacht, we often encounter pods gliding through calm fjords or surfacing near glaciers. The rich coastal ecosystem provides excellent feeding grounds, and sightings are frequent during summer.
In addition to orcas, these waters are home to humpback whales, sea lions, bald eagles, and harbor seals, creating a diverse range of photo opportunities. Calm seas and dramatic backdrops of misty forests and ice-filled bays make every encounter an incredible experience.

Conservation Status
Globally, orcas are listed as Data Deficient by the IUCN, since their populations vary widely across regions and are difficult to assess as a single species. Some groups, however, face serious threats. The Southern Resident orcas of the Pacific Northwest are listed as Endangered under the U.S. Endangered Species Act, with population declines linked to reduced salmon runs, pollution, and vessel noise. Conservation efforts continue to focus on restoring prey abundance and protecting critical habitat.

Best times: Summer months, when salmon runs attract pods closer to shore and conditions are ideal for photography.Where to look: Coastal fjords, bays, and channels, especially where baitfish or salmon are plentiful.
Photography tip: Use a fast shutter speed to freeze action when orcas breach or tail-slap. Continuous shooting mode helps capture their unpredictable surfacing behavior.
Composition: Include surrounding scenery such as glaciers, misty mountains, or reflections on calm water to add context and drama to your images.
Behavior cues: Watch for blows and dorsal fins breaking the surface, or birds circling above schools of fish, which can signal nearby orcas.
