The black rhino is disappearing rapidly in its native eastern and central Africa, making it an endangered species.
Not so at the San Diego Zoo Safari Park, where 15 black rhinos have been born.
The latest is a week-old male, as yet unnamed. He is the fifth offspring of Lembe and her mate Jambia.
At 100 pounds, the baby will get much larger. An adult black rhino can be 5 feet tall at the shoulder and weigh upward of 3,000 pounds.
The calf spends much of his time trailing Lembe. Her tail is pointed straight up -- which is rhino-speak for "follow me."
