You probably recognize polar bears for their white coats and frozen habitat, but have you ever wondered what people call a female polar bear? A female polar bear goes by the name “sow.” That word might sound simple, but it hints at her huge role raising cubs and surviving those brutal Arctic winters.
Just picture a mother leading her tiny cubs across shifting sea ice, or digging a den to shelter them from the cold. Curious about what sets sows apart from males? Or how they care for their young? Let’s dig into what makes these mothers so important to the Arctic.
What Is a Female Polar Bear Called?
People use a specific name for an adult female polar bear, and it’s pretty consistent with what they call females in other bear species. Here’s how it fits with other bear terms, and where you might see it pop up.
Meaning and Usage of the Term ‘Sow’
We call a female polar bear a sow. That’s the same term folks use for adult female bears across most species.
You’ll spot “sow” in wildlife documentaries, at the zoo, or in research papers when someone means an adult female, especially one raising cubs.
“Sow” refers to Ursus maritimus—the scientific name for polar bears—and highlights the adult female’s role. You might also hear people call them sea bears, white bears, or ice bears, but those names talk about the species as a whole, not the sex.
When someone says “sow,” they’re usually talking about an adult female, maybe one with cubs or one preparing her den for winter.
How the Name Differs From Male and Other Bear Species
People call male polar bears boars, and the young ones are cubs. These terms match up with what we use for other bears, like brown or black bears.
So, if you read about a boar or a sow, you know right away whether you’re talking about a male or female. Pandas are technically bears, but honestly, you don’t often hear someone call a female panda a sow in casual conversation.
With polar bears, those other names—sea bear, white bear—just talk about where they live or what they look like. If you want to be clear, use sow for a female, boar for a male, and cubs for the little ones.

Key Characteristics and Life of Female Polar Bears
Female polar bears tend to be smaller than their male counterparts. They also lead the way when it comes to raising cubs and rely on sea ice to hunt seals that give them the fat they need for reproduction and nursing.
Physical Differences Compared to Males
You’ll notice female polar bears don’t get as big as the males. Most adult females reach about 6–8 feet in length, while males can hit 8–10 feet.
Females usually weigh between 330–550 pounds. Males? They sometimes top 1,200 pounds.
Both sexes have that thick white fur, a hefty layer of fat, and black skin underneath—it all helps with staying warm and blending in. Females tend to have less bulk around their neck and shoulders.
This size difference affects how far they roam and how much energy they need, which connects directly to how they hunt and raise young.
Maternal Role and Raising Polar Bear Cubs
If you ever watch a female polar bear, you’ll see she handles almost all the parenting. She gives birth in a snow den during winter after delayed implantation, usually having one or two cubs.
Cubs start out tiny and rely on their mother’s rich, fatty milk to grow quickly. The mother sticks with her cubs for about 2–3 years.
During that time, she teaches them everything—how to wait at a seal breathing hole, how to stalk prey on the ice. She’ll go without food for long stretches while denning and caring for her cubs, living off her stored fat.
When sea ice shrinks, it gets harder for her to hunt seals, which means cub survival rates drop. That’s one reason scientists worry about polar bear populations and their vulnerable status.
Habitat and Diet in the Arctic Region
When you think about female polar bears, you can’t really separate them from sea ice or the Arctic itself. These bears move between their dens on land and the hunting grounds out on the sea ice, sticking close to the coastlines and bays.
They mainly go after ringed seals and bearded seals. Those seals give them the fatty meals they absolutely need.
But here’s the thing: shrinking sea ice cuts hunting seasons short. That forces the bears to fast for longer stretches.
This shift hits female polar bears hard. Their bodies get weaker, they don’t reproduce as often, and their cubs might not make it.
In places where sea ice still sticks around, females claim territory near seal haul-outs and breathing holes. That way, they boost their chances of catching food and can keep their cubs safer.
