Harbor seal Qilak gave birth to a 22.6-pound female pup Monday, the Point Defiance Zoo & Aquarium’s second in eight days.
Both newborns are bonding with their mothers behind the scenes, and have yet to be named.
The male pup is “already becoming quite a swimmer,” said Neil Allen, curator of aquatic animals.
The newborns need time to nurse and gain a layer of blubber to regulate their own temperatures, according to the zoo. It could be a couple weeks before they make their public debuts.
