Two Harbor Seal Pups Join the Pod at Zoo Berlin
July 28, 2018
On a recent morning, keepers at Zoo Berlin began their daily inspection of the Harbor Seal habitat. One of the keepers’ first tasks is to perform a head count of the seven animals under their care. As they began to count, they noticed not seven pairs of dark eyes staring back at them, but eight! It soon became clear that female Shiva, age 23, gave birth to a pup during the night. A few days later, the same scenario: now there are nine Seals in the habitat! This time Molly, age 13, is the proud mother of a brand-new pup.

Zoo Berlin is home to a large extended family of Harbor Seals. Male Leopold, age 21, sired two pups last year. His sons Gregor and Herbert are still part of the group, which also includes females Lara, age 18, and Yohanna, age one.
Harbor Seals have a gestation period of up to eleven months. Pups are born with the same smooth fur as the adults and can swim almost from birth.
Harbor Seal pups are weaned at around two months old. “Seal pups are much more vulnerable to attack on sand banks than they are in the water, so they have to grow up quickly,” explains Zoo and Tierpark Director Dr. Andreas Knieriem. “Before too long, the newborn Seals will be almost indistinguishable from their parents.”
In the wild, these aquatic mammals are found all over the northern hemisphere – on the Atlantic and Pacific coasts as well as in the North Sea and the Baltic. However, they are very rare on the northern European coasts. Commercial hunting of Harbor Seals was banned several decades ago in most countries around the world. Only native peoples are permitted to hunt these seals for subsistence hunting.
