Key takeaways
- Killer whale and orca are two English names for the same species, Orcinus orca. Neither name is more correct than the other.
- Orcas and humpback whales share the fjords around Skjervoy because both are feeding on the herring that winters here from October to late January.
- The orcas found from the boat travel in family groups that range from a handful of animals to a much larger gathering, and the number changes from one day to the next.
- No trip can promise a sighting. The boat goes out because this is where the animals have been feeding, not because any single crossing is certain to find them.
Killer Whale and Orca Are the Same Animal
Killer whale and orca describe one and the same animal, Orcinus orca. Neither word is a nickname for the other or a softer version of it; they are simply the two names English speakers use, and which one a guide reaches for on the day tends to be a matter of habit rather than meaning. If a leaflet or a guide says orca and another says killer whale, both are talking about the black and white animal working the same stretch of water off Skjervoy.
The name killer whale is also, strictly, a misnomer worth knowing before you go looking for the animal: it is not a whale in the baleen or sperm-whale sense at all, but the largest member of the dolphin family. That does not change anything about what you will see from the boat. It is worth knowing only because the confusion around the name is exactly the kind of question a first-time visitor tends to ask on the way out to Skjervoy.
Why the Fjords Fill With Whales in Winter
The reason orcas and humpback whales are both in these waters at the same time is straightforward: herring winter in the fjords around Skjervoy, and both species come to feed on the same shoals. The tour runs from October to late January because that is the window when the herring are here, not because of anything to do with the whales' own calendar. Once the herring move on, so do the animals that follow them.
That shared food source is also why you should not expect to see only orcas. A boat that finds one species working a shoal has a reasonable chance of finding the other nearby, because a dense ball of herring near the surface is a resource neither animal has any reason to ignore. Other cetaceans turn up here too, on occasion, drawn by the same herring.
A dorsal fin breaks the surface as gulls gather over the same herring shoal off Skjervoy.
Telling One Animal From the Other
From a low seat on a small boat, the two species are easier to tell apart than photographs suggest. An orca surfaces in a fast, low roll, and an adult male carries a dorsal fin tall enough to be visible well before the rest of the animal breaks the surface. Orcas also travel and surface in coordinated groups, several fins appearing and vanishing together as the pod moves as one.
A humpback whale surfaces more slowly and shows far more of its back and a smaller, curved dorsal fin set well down the body. Before a deep dive it will often lift its tail clear of the water, a broad fluke that an orca never shows in the same way. Size is the other giveaway: a humpback dwarfs an orca surfacing beside it, even without a tape measure to prove it.
What a Pod Looks Like From the Water
Orcas here move in family groups, and the group you find on any given day is not a fixed size. Sometimes it is a handful of animals moving together; on another crossing the guide may find a much larger gathering, several family groups feeding on the same herring at once. There is no number worth memorising before you go, because the pod you meet depends on where the herring happen to be that week.
What stays constant is the way a pod behaves around a feeding shoal: animals surfacing in twos and threes, diving and reappearing a short distance on, rather than one whale doing one obvious thing. Watching a pod work a shoal is closer to watching a slow, spread-out event than a single dramatic moment, and it can go on for longer than a single photograph suggests.
2 species
Orcas and humpback whales feed on the same wintering herring off Skjervoy, which is why both turn up in the same water.
The Birds That Find the Whales First
White-tailed eagles and large numbers of gulls work the same herring the whales are feeding on, and they are often the first sign that something is happening on the water. A gathering of gulls circling and diving over one patch of fjord, with an eagle or two overhead, is a strong clue that fish are being pushed to the surface, whether by orcas, humpbacks, or both.
Guides read these birds the way a driver reads brake lights ahead: not proof of a whale, but a reason to head that way and look properly. By the time the boat arrives, the birds are usually still there, working the same patch of water the whales have driven the herring into.
What a Sighting Is Actually Like
Most sightings start as a sound before they are anything you can point a camera at: a sharp exhale as a whale blows, carrying further over flat water than you would expect from a low seat on a small boat. Then a fin, dark against grey water, there and gone. From sea level, with no upper deck to look down from, a fin at close range looks larger and closer than the same animal would from a big ship's rail.
What follows is rarely one long, continuous show. A pod or a lone humpback surfaces, breathes, and goes back under, sometimes in the same spot and sometimes a hundred metres further on by the time you have turned to look. The guide keeps the engine low and repositions quietly rather than chasing, which means some sightings are brief and some run on for a long stretch, and neither the length nor the number of animals is something anyone can set in advance.
Say plainly what this means for the day: sightings here are never guaranteed. The season is timed to when the herring, and therefore the whales, are reliably in these fjords, and the crews are looking in the right place for the right reason. That is not the same as a promise, and a page that told you otherwise would be lying to you before you had even booked.
