Ringed Seal

Pusa hispida

LCLeast Concern

Ringed seals are the smallest true seal in Arctic waters, and the only one that builds its own shelter: a snow-roofed lair scratched out over a breathing hole in the ice, where a mother hides her pup from predators above and below. That lair habit sets the species apart from every other ice seal sharing Alaska's coast. The records below trace its presence across the Bering and Chukchi seas, the state that holds its entire US range.

Life history

The Ringed Seal (88.1 kg194.2 lb) is a carnivore that first breeds around 5 years, carries a 251-day gestation, and bears about 1 young per litter. Maximum recorded longevity is 46 years.

Animals people sometimes mistake for the ringed seal, and how to tell them apart.

How to tell a ringed seal from its ice-seal neighbors

Three seals share Alaska’s sea ice and get mixed up constantly: ringed, spotted, and bearded. The ringed seal is the easiest to sort out once you know what to look for. Its dark coat is broken up by pale, ring-shaped blotches, which is different from the dense, well-defined round spots of a spotted seal or the plain, mostly unmarked body of a much larger bearded seal. It’s also noticeably smaller than either relative, with a compact, rounded head and a short, cat-like muzzle framed by long whiskers.

The smallest seal that builds its own hideout

No other Arctic seal does what a ringed seal does with snow. It keeps several breathing holes open in landfast or drifting ice through the winter, scratching each one clear with strong foreflipper claws. Over one hole, it digs a snow-roofed lair where it can rest and, come spring, give birth. That lair works as real insulation and real camouflage. It hides a seal, and later its pup, from a world where danger comes from the sky and the ice surface, not just the water below. It’s a strategy built for an animal that stays tied to stable ice for its whole life, rather than ranging widely over open water.

Fish-heavy diet in a frozen sea

Fish make up most of a ringed seal’s diet, arctic cod especially, alongside capelin and other small schooling species. Shrimp and other invertebrates round out the rest. That fish-heavy menu fits a body built for short, repeated dives near the ice edge, not the longer foraging runs of a bulkier animal like the bearded seal. Ringed seals hunt through their own maintained breathing holes as much as through open leads in the ice. The lairs described above do double duty: shelter above, and a base for feeding trips underneath the ice.

Pups hidden from wolves, foxes, and bears alike

A ringed seal pup is born inside its mother’s snow lair, wrapped in a woolly white coat that blends into the walls around it. That hiding spot matters. Ringed seal pups face threats from land as much as from the sea. Polar bears specialize in breaking into lairs from above. On the Alaska mainland, gray wolves and both red and Arctic foxes will do the same wherever a lair sits within reach of shore. Nursing lasts only a few weeks on rich, fatty milk before the pup is weaned and left to fend for itself in open water. Adults mate again near the end of that nursing period, so the whole cycle, from birth to an independent young seal, moves fast.

Common now, but tied tightly to ice

The IUCN lists the ringed seal as Least Concern. It’s thought to be the most numerous seal in the Arctic overall. Alaska’s population ranges the length of the Bering, Chukchi, and Beaufort seas, with records reported here in every month of the year. That stability comes with a catch. This is a species that needs snow deep enough to build a lair and ice stable enough to hold one. Both are getting harder to count on as the Arctic warms and ice seasons shorten. Numbers hold up across most of the range for now, but few Arctic mammals are watched as closely for what a changing ice season might do next.
