Meet a baby Javan rhino, possibly the rarest infant mammal on Earth. Biologists estimate that there are only 40 or so Javan rhinos left in the world. Scientists worry they could be wiped out very soon by human poachers or a volcanic eruption.

The video and photo below were obtained by the World Wildlife Fund-Indonesia with motion-activated cameras. The cameras have been a boon for researchers trying to find rare species in the wild. Cameras don't smell like animals and they can stay in place for very long periods of time.

(Also, I smell a Pixar movie about the Javan rhino's plight.)
