It is estimated that about 3500 pups were born at the Piedras Blancas rookery in 2005. Pups weigh up to 75 pounds at birth and may be four feet long. When they are first born they carry a striking dark black, smooth coat which will gradually fade to brown as the pup matures. Feeding on its mother's rich milk (55% fat), the pup grows to 250-350 pounds in less than a month. Some resourceful pups nurse from two or three females; they can weigh 600 pounds and are aptly called 'super weaners'.
