A new Javan rhinoceros calf has been spotted at an Indonesian national park, giving hope for the conservation of one of the world's most endangered mammals.

The calf, estimated to be between three and five months old, was spotted in footage obtained Thursday by one of 126 camera traps installed in Ujung Kulon National Park on Java island.

The mammal, whose sex remains unknown, was seen to be walking with its mother inside the park, the last remaining wild habitat for Javan rhinos.
