Pangolins are one of the planet's most unique and adorable species. The scaly, anteater-like creatures live in parts of Asia and Africa, and there's an entire task force dedicated to their protection. A popular Pokemon character, Sandslash , was even based on these "artichokes on legs ."

And yet, humans can't seem to stop killing them.

Authorities in Indonesia recently busted smugglers trying to transport 1.3 tons worth of dead pangolins into Singapore. Heart-wrenching photos taken by a Getty photographer show dozens of the animals frozen in their trademark armored ball before they were burned by customs officials on Wednesday.

Pangolins are the world's "most-trafficked " mammal. The International Union for Conservation of Nature classifies the Chinese pangolin -- one of eight species of pangolins -- as "critically endangered ."

"The pangolin runs the risk of becoming extinct before most people have even heard of them," Britain's Prince William said last year .

Pangolins have suffered due to their relative obscurity compared to other, better-known endangered species like polar bears.

Thats one of the problems with species like pangolins, Annette Olsson, an adviser for Conservation International, told the Times earlier this year. Its not huge and not very charismatic. Its small and weird and just disappearing.

But concerned nations plan to vault them to the forefront of conservation efforts during next year's Convention on International Trade in Endangered Species of Wild Fauna and Flora meeting in Vietnam.

"We consider pangolins a priority species and fear that without concerted and strategic international cooperation and action, pangolins will disappear," the U.S. Fish and Wildlife Service wrote earlier this month.
