Brief Introduction ：
we recorded the whole process
of a Wader seal giving birth to a baby seal: the
little seal finally managed to get out of the embryo,
opened its curious eyes and fought its way for milk.
Elephant seal is biggest in figure among the seal
family. Their marital system is polygyny. The one
who wins over in fighting for domain and mates would
be the natural leader.
One morning, in our Great Wall Station came a special
guest. A elephant seal fell asleep on a mattress
basked in the sunshine.
