TACOMA, Washington -- Two newborn harbor seal pups greeted the public for the first time at Tacoma's Point Defiance Zoo and Aquarium on Thursday.
The pups were born earlier this month within eight days of each other. Eight-year-old harbor seal Shila gave birth to a male pup on June 2, and nine-year-old Qilak had a female pup on June 10.
The seals and their pups have been living behind the scenes as the pups nursed and gained weight. New pups need time to bond with their mothers and gain a blubber layer to regulate their temperatures in the water. Both pups are already swimming well.
Point Defiance Zoo and Aquarium now has six harbor seals: Blackie, 37; Louise, 36; Shila, Qilak and the two pups.
