Bundle of joy.

Last July, Cincinnati Zoo veterinarians celebrated a special delivery. A Sumatran rhinoceros named Emi gave birth to her second baby--a 34 kilogram (75 pound) female named Suci (SUE-chee). That made Emi the first of her species to produce more than one baby in captivity.

In the wild, fewer than 300 Sumatran rhinos, Dicerorhinus sumatrensis (dy-SER-oh-RY-nus SUEma-TREN-sis), remain. Poachers (illegal hunters) kill the animals. Plus, humans are destroying their forest habitat (region where an organism lives) in Malaysia and Indonesia.

Rearing captive rhinos--like Suci and her older brother--can keep the endangered species (group of organisms in danger of dying out) from disappearing, says Dr. Terri Roth, vice president of animal sciences at the Cincinnati Zoo. "[We wanted] to make sure we had more Sumatran rhinos if we lost the wild population," she says. Suci's birth could also help start other breeding programs. Way to go, rhino!
