London Zoo shows off baby pygmy hippo

LONDON (KGO) -- London Zoo is showing off its latest addition and it's adorable.

A male pygmy hippo calf was born Dec. 26. Zookeepers say male calves are extremely rare. Pygmy hippos are endangered in the wild.

The little guy only weighs about 22 pounds now, but he'll likely grow to more than 600 pounds over the next year or two.

He does not have a name yet.
