A mother Atlantic walrus watches over her pup on an ice floe near Igloolik, Nunavut, Canada. Pups can swim within hours of their birth but stay with their mothers for up to two years before going off on their own. Mothers teach their pups crucial skills, such as how to spot polar bears and how to haul out onto the ice using their tusks.
