Among the animals are two pig-tailed macaques, two long-tailed macaques, one bald-headed uakari, one wild cat, one Oriental rat snake, one yellow-headed temple turtle, one reticulated python, and one Indian python.
All of them belong to Group IIB of Vietnam's Red List, which means animals that are endangered or rare.
They were handed over to forest rangers by local people. They had been either captured by poachers or accidentally fell into traps that were set for other animals.
Rangers took care of them for a period of time and made sure they would be healthy enough to live on their own in the wild before releasing them.
