And then there were two.

One of Malaysia’s last three Sumatran rhinos (Dicerorhinus sumatrensis) was euthanized this past weekend to relieve her suffering from untreatable cancer. Puntung, a 25-year-old female, survived a poacher’s trap as a calf, leaving her with just three feet for most of her life. Conservationists captured her from the wild in 2011 and she has spent her time since then living at Tabin Wildlife Reserve.

The Borneo Rhino Alliance estimates that fewer than 100 rhinos from this critically endangered species still exist in all of Indonesia, where their remaining populations cling on in small, fragmented populations.
