I was extremely excited to be able to photograph these absolutely beautiful siamangs in such a short distance, my mind was blown away...Siamang is the largest gibbon species, twice as large as the other gibbons. They are frugivorous, but also eat flowers, leaves and insects. They live in the rainforests and montane forests in Sumatra, the Malayan Peninsula and the southern tip of Thailand. It's a dream to see them in their natural habitat, and I was totally satisfied. (2 March 2023, West Sumatra).

Saw this beautiful lizard in a lowland rainforest near Padang West Sumatra; not sure if it is a green crested lizard (Bronchocela cristatella) because it does not have a dark ring around each eye.

Sumatran Orangutan (Pongo abelii， 苏门答腊猩猩）。 One of the most exciting moments of our Sumatra expedition is seeing these wild hominids, our closest relatives in nature, in their natural habitats. I feel honored and extremely lucky to encounter them; meanwhile, I feel sad on the other hand for their current situation, i.e., they are critically endangered and losing their habitat to humans... (SE Aech, lowland rainforest, 400m)

I am not a herpetologist, but I hope my ID (Gonocephalus beyschlagi) for this beautiful lizard in southern Aceh Province's lowland rainforest (400m) is correct. If not, free feel free to correct me.

Insect of Sumatra: Pyrops ruehli, a plant sap-sucking insect found in Sumatra and peninsular Malaysia.
