Unsurprisingly, the world's rarest rhinos tend to be somewhat camera shy — but now two of them have been caught on film in the jungles of Southeast Asia.
Javan rhinos can only be found in two places in the world.
There is believed to be up to 50 of them in the Ujung Kulon National Park in Java and no more than eight of them in Cat Tien National Park in Vietnam. None exist in captivity.
A team led by the campaign group WWF installed specially designed video cameras in Ujung Kulon and managed to capture a mother rhino and her calf on video.
Unfortunately, after inspecting the camera, the mother rhino became a little overexcited and charged the camera, sending it flying.
Adhi Rachmat Hariyadi, who leads WWF-Indonesia's project, was unperturbed.
He said: "With fewer than 60 Javan rhinos left in the wild, we believe this footage was well worth the risk to our equipment. "It's very unusual to catch a glimpse of the Javan rhinos deep inside the rain forest."
