Prague Zoo has welcomed its first Alaskan or Dall Sheep lamb. The birth is relatively rare for zoos in general. While the fluffy white lamb's sex is as yet undetermined, if it is male, it will grow long curled horns. The new lamb is playful and able to spring about with dexterity, even at this young age. Its wild cousins use these skills to navigate the rugged and inhospitable terrain of the Alaskan wilderness.
