Apparent twin pups of the weddell seal near Mawson, Antarctica
Phocid seals give birth annually, generally to a single pup. Twins have been reported occasionally, either from observations made in utero or from observations of live pups in the field. Examples of the former are reports of two embryos in a Weddell seal, Leptonychotes weddellii and of twin foetuses...

Twins have been reported occasionally, either from observations made in utero or from observations of live pups in the field.

For southern elephant seals, an adult female that expelled two placentae and gave birth to a pup while another newborn pup was nuzzling the female, has also been reported.
