It's a lot of pressure for a five-year-old rhinoceros to have to save his species from extinction. But that's the challenge facing Andalas, the first Sumatran rhino born in captivity in more than 100 years. Two weeks ago, Andalas traveled from the Los Angeles Zoo, in California, to a sanctuary on the island of Sumatra, in Indonesia. There, Andalas will take part in a breeding program that could save his species. The Sumatran rhino is considered the most threatened of the five rhino species. There are now fewer than 300 Sumatran rhinos alive. They are in isolated parts of forests in Malaysia and Sumatra.
