A Weddell seal (Leptonychotes weddellii) usually gives birth to around 1 babies.

Each of those little ones spend around 314 days as a fetus before they are released into the wild. Upon birth, they weight 27.4 kg (60.4 lbs) and measure 10.7 cm (0′ 5″).

The Weddell seal (Leptonychotes weddellii) is a relatively large and abundant true seal (family: Phocidae) with a circumpolar distribution surrounding Antarctica. The Weddell seal was discovered and named in the 1820s during expeditions led by British sealing captain James Weddell to the area of the Southern Ocean now known as the Weddell Sea. The life history of this species is well documented since it occupies fast ice environments close to the Antarctic continent and often adjacent to Antarctic bases.
