No. They're mammals, they give birth to pups. The above answer is incomplete: There are egg-laying mammals in the southern hemisphere. The class Mammalia is split into two subclasses: Prototheria (egg-laying) and Theria (live birth). There are only 2 families and 3 living genera among the prototherms, which consist of the platypus and echidnas. Their eggs, soft and short-lived, differ from birds, and they seek nourishment by their mother's milk in infancy like other mammals. Otters and sea lions are therians, giving live birth, but they do exhibit delayed implantation, which differs from some mammals. This basically means that after fertilization, the embryo doesn't immediately attach to the uterus, but instead several months pass before attaching. It's believed that seasonal changes during the lag period will favor survival of their young. Delay time varies by species.
