A long-tailed macaque (Macaca fascicularis) is seated on the rocky and sandy ground in a natural, forested environment within Khlong Sok, Thailand. The macaque, exhibiting brown-grey fur with a lighter underside, is oriented towards the right and slightly upwards, its left hand resting on its chest. Its tail extends horizontally behind it on the uneven ground, which is strewn with small stones and dry leaves. The background consists of dense tropical foliage, with a cluster of bamboo stalks visible on the right and various broadleaf plants on the left, all illuminated by diffused natural light filtering through the canopy. No other individuals or significant objects are visible, and no discernible interaction is occurring beyond the macaque's posture of observation.
