It is estimated the population of the banded palm civet has decreased by around 30% in just three generations. Banded palm civets are usually approximately the size of a domestic cat; their fur is pale but with dark bands on the back.
The common green frog is a frog species of in the true frog family Ranidae; some sources still use the old name Rana erythraea. It lives in Southeast Asia and is also known as green paddy frog, red-eared frog or leaf frog.

Pulchrana debussyi is a species of true frog, family Ranidae. It is endemic to Sumatra, Indonesia. It is only known from its type locality in the Batak Mountains. The holotype is now lost, and there are concerns about validity of this taxon—it might be a synonym of Sylvirana nigrovittata. Common name Battak frog has been proposed for it.

Later on, it has also been recorded in the province of Jambi in east-central Sumatra. Pulchrana centropeninsularis is a rare species known from few individuals only.
