A young Pacific Harbor Seal pup with milk on its face from nursing. Mother harbor seals will only nurse their pups for about four to six weeks, at which point the small seal is weaned and must begin to forage and fend for itself. That short period of time is crucial for the young seal to learn how to hunt, socialize and swim.
