The animals were seized from smugglers by police this week at the border between Vietnam and Laos, and suspects were taken in for questioning.
Now the the people at Save Vietnam's Wildlife are working tirelessly to help the pangolins - the most illegally trafficked mammal on Earth - survive.
But it's touch and go with their dozens of new patients because the animals are very weak after they were force-fed corn powder to make them weigh more (and increase their value) and tied up in tiny bags.
"This made them really weak," Phap Nguyen, communications officer for Save Vietnam's Wildlife, told The Dodo. The pangolins were caught in the wild using traps, which caused injury to many of the animals' little arms and claws.
"This big rescue added up to 130 pangolins in our quarantine right now, which is over our capacity," Nguyen said. "As a result, three or four pangolins have to share a room - not good for them but we have no other choices."
Already, one pangolin has died due to his injuries, and Nguyen fears they could lose more. "Several others look really bad," he said. But rescuers aren't giving up.
The rescue of the 70 pangolins is the biggest Save Vietnam Wildlife has had so far. "We really need help for this case," Nguyen said.
You can help these pangolins have a fighting chance. The Wildlife Conservation Network is helping Save Vietnam Wildlife with this huge influx of patients by doubling all donations sent through this page.
