Veterinarian Larry Vogelnest cares for 4,000 animals at Australia's Taronga Zoo, but he says one of the most exhilarating aspects of his job is conservation work. He recently traveled to Vietnam to help save the Cat Ba langurs, a primate species with an estimated 50 remaining individuals. Dr. Vogelnest and his team trekked to a small island to capture, collect samples from and transport two isolated Cat Ba langurs. The team moved the animals in the hopes they would breed. "I felt that I could really make a significant difference to saving a species from extinction," Dr. Vogelnest said.
