They once roamed the jungles of South East Asia and India, but today only 67 exist in the Ujung Kulon National Park, which was hit by last week's tsunami.
The park sits in the shadow of Anak Krakatau, the volcano which triggered waves that killed hundreds of people.
The volcano remains active and officials are now rushing to move them.
Two park officials were among the 430 killed by the tsunami, and numerous park buildings and ships were also destroyed when the tsunami hit last Saturday.
But the Javan rhinos left in the park - the only ones left in the world - were left unscathed.
The rhinos typically live along the park's south coast and this tsunami hit the north coast - many are keenly aware that the rhinos might not be so lucky if there is another disaster.
