Along the Norwegian coast, from the sheltered fjords of the south to the icy waters of Svalbard, three seal species are most likely to be encountered: the grey seal (Halichoerus grypus, havert), the harbour seal (Phoca vitulina, steinkobbe), and the bearded seal (Erignathus barbatus, storkobbe). While all are pinnipeds, they differ markedly in appearance, behaviour, and preferred habitat. Knowing these differences not only enriches your wildlife observations but also helps you identify them responsibly from a distance.
Grey Seal (Havert): The Large, Hook-Nosed Resident
The grey seal is the largest of the three species found along the Norwegian mainland. Adult males can reach up to 3 metres in length and weigh as much as 300 kilograms, while females are smaller, typically around 2 metres and 150–200 kilograms. The name 'grey' refers to the mottled grey-brown coat, but colour varies individually, with some appearing darker or lighter.
The most distinctive feature is the male's long, convex 'roman nose' — a straight, sloping forehead that gives the head a horse-like profile. Females have a more delicate, dog-like face. Grey seals are often seen hauled out on remote skerries and islands, particularly along the coast from Rogaland to Finnmark, and they favour rocky shores and sandy beaches where they gather in colonies during the breeding season.
Harbour Seal (Steinkobbe): The Smaller, Dog-Faced Companion
The harbour seal, or common seal, is smaller than the grey seal, with adults reaching 1.5–1.9 metres and weighing 80–120 kilograms. Its head is round with a short, blunt snout and a distinct 'dog-like' appearance, lacking the grey seal's roman nose. The coat is typically grey or tan with dark spots, and the nostrils are V-shaped, meeting at the bottom, unlike the grey seal's more parallel nostrils.
Harbour seals are the most widely distributed seal on the Norwegian mainland, found in sheltered bays, estuaries, and fjords from the Oslofjord to the north. They are often seen in small groups, hauling out on sandbanks, mudflats, and rocky ledges that are exposed at low tide. They are more coastal and less pelagic than grey seals, rarely venturing far from shore.
Bearded Seal (Storkobbe): The Arctic Giant with Whiskers
The bearded seal is a true Arctic species, most commonly encountered in Svalbard waters, though it may occasionally stray to the northernmost parts of the mainland. It is a large seal, comparable in size to the grey seal, reaching up to 2.5 metres and weighing 250–300 kilograms. Its most striking feature is a dense, bushy moustache of long, white whiskers (vibrissae) that curl downward, giving it a 'bearded' appearance.
Unlike the grey and harbour seals, the bearded seal has a small head relative to its bulky body, and its foreflippers are square and broad. Its coat is usually grey-brown with darker patches, often appearing paler on the belly. Bearded seals are solitary and prefer drifting sea ice, where they rest and give birth. They are rarely seen on land, and their presence in Norwegian waters is largely restricted to the pack ice of the High Arctic.
Key Identification Tips at a Glance
When observing seals from a respectful distance, focus on three features: size, head shape, and habitat. Grey seals are large with a long, sloping nose (males) and are often found in groups on rocky islands. Harbour seals are smaller with a round, dog-like head and are common in sheltered coastal waters. Bearded seals are large but have a small head with prominent whiskers, and they are almost exclusively seen on sea ice in Svalbard.
Another useful clue is behaviour: harbour seals are more agile and often 'bottling' vertically in the water, while grey seals tend to rest with their head and hind flippers raised. Bearded seals are usually solitary and will dive quickly if disturbed, often making a characteristic 'haul-out' on ice floes. Always use binoculars or a telephoto lens to avoid stressing the animals, and never approach a haul-out site.
Respectful Observation and Conservation
All seals in Norwegian waters are protected, and disturbing them is illegal. During the breeding and moulting seasons (winter for grey seals, summer for harbour seals, and spring for bearded seals), seals are particularly vulnerable. Keep a distance of at least 100 metres from haul-out sites, and if a seal raises its head or moves towards the water, you are too close.
By learning to identify these species, you contribute to citizen science and help monitor their populations. Report your sightings to local wildlife databases, but always prioritise the animal's welfare. The Norwegian coast and Svalbard offer remarkable opportunities to see these marine mammals, and with careful observation, you can enjoy them without causing harm.
