How much does a baby seal and an adult seal weigh. Out of 35 species of seals, six types live in Antarctica (Antarctic Fur Seals, Crabeater Seals, Leopard Seals, Ross Seals, and Weddell Seals). These six species make up the majority of the world's seal population. Average adult Antarctic Fur Seals weigh Up to 700 lbs (317 kg). A fur seal cow gives birth to one pup per year, and mates again shortly thereafter. Crabeater Seals are large seals of about 220kg (484lb).
