But they are also the world's most heavily trafficked mammal, and experts at the Convention on International Trade in Endangered Species (CITES) conference this week are ringing alarm bells over their survival.
Demand for pangolin meat and body parts has fuelled a bloodbath, and driven the scale-covered, ant-eating mammal towards extinction.
More than a million pangolins are believed to have been poached from the wild in the past decade.
Most are used to supply demand in China and Vietnam, where they are highly regarded as a delicacy and an ingredient in traditional medicine.

"The pangolin today is regarded as the most heavily trafficked mammal in the world," CITES chief John Scanlon told AFP.
"There has been a massive surge in the illegal take of the pangolin for its meat and for its scales."
Currently CITES allows for trade in pangolins but under strict conditions.
"Existing laws are clearly failing to protect pangolins from the poachers. A complete international trade ban is needed now," said Heather Sohl, WWF-UK's wildlife advisor.
There are four species of pangolin in Africa and four in Asia.
Research published in the early 2000s estimated populations in China to have declined by up to 94 percent, said Dan Challender, pangolin expert at the International Union for Conservation of Nature.
Pangolins are covered in overlapping scales, and have pink, sticky tongues almost as long as their bodies.
When physically threatened, they curl into ball, making it easy for them to be picked up by hunters and put into a sack.
About the size of a small dog, they are solitary, mostly nocturnal and cannot be farmed.
India, the Philippines, Vietnam, Nigeria, Senegal and the United States are co-sponsoring the proposal to impose a total ban on pangolin trade.
