Traffic, which monitors such activity, said many of the species, despite having international protection, were not native to the country, and so trading them was unregulated.
The listings were found on 12 Facebook groups during one month in 2016.
Facebook said it did not allow the trade of endangered species.
Among the 200 different species listed for sale were two non-native species banned from international commercial trade - the Eurasian otter and the black spotted turtle.
