Seals live in the arctic and Antarctic. Some seal species depend entirely on the ice for survival where they give birth and nurse their pups. They search for food along the edge of the ice and beneath it.
Most seals never leave the ice pack. Six seal species live in the arctic: harp, hooded, ringed, bearded, spotted and ribbon. They make holes in the ice for fishing, and they protect their young in snow mounds. Polar bears are their primary predator. Only four species of seals live in Antarctica, but they far outnumber arctic seals. Killer whales are threatening predators, but the leopard seals are the primary cause of death.
