A rare Sumatran rhino in Indonesia is pregnant with her second baby and expected to give birth in May, raising new hope for the critically endangered species, conservationists said Tuesday. Only about 100 Sumatran rhinos are believed to exist in the entire world so the pregnancy is seen as tremendously good news for those trying to save the animals from extinction. The mother is Ratu, a wild rhino who wandered out of the rainforest and into the Sumatran Rhino Sanctuary in Indonesia's Way Kambas National Park 10 years ago.
