The ice itself is habitat for animals such as seals, Arctic foxes, polar bears, and penguins., Life thrives along the margins of sea ice, as melting and freezing enhance circulation and bring nutrients to the surface. This change in the suns position from winter to summer means that more energy's reaching the ocean and therefore warms the water.
