A rare spotless giraffe was born in a Tennessee zoo

A female reticulated giraffe was born at Brights Zoo in northeastern Tennessee late last month - but unlike her mother she was born without any spots, a rarity.

Standing 14 to 15 feet tall, giraffes are the tallest mammals in the world. When mothers give birth, the calves are already 6 feet tall, and other than on especially rare occasions, they're born covered from hoof to horn in brown spots. Brights Zoo announced that it welcomed the birth of a reticulated giraffe without any spots on July31. "Giraffe experts believe she is the only solid-colored reticulated giraffe living anywhere on the planet," said the zoo.
