The pale-thighed surili[1] (Presbytis siamensis), also called the white-thighed langur, is a primate species in the Old World monkey family (Cercopithecidae).
- This species lives arboreal in submontane forests. It is endemic to the Thai-Malay Peninsula, Sumatra, and the Riau Archipelago.
- This slender little monkey is so cute! Coppery eyes peer coyly from beneath a plump brown or gray cap that nestles in a triangular formation around the nondescript brow ridge.
- Mother Nature outlined the skin around the eyes in pale pink and used the same color scheme to outline the monkey’s lower lip, adding more contrast to the dark skin of the face.
- She then endowed this surili with a long aquiline nose and wisely delineated them with modest nostrils. The overall effect is an expressive and seductive face.
- The species gets its name from the pale (or white) fur outside its thighs.
- The belly is also covered in white fur, and long white fur billows out from the face, almost obscuring the monkey’s dark snail ears.
- Long, brownish-gray fur covers the arms, back, lower legs, and tail, contrasting with the abundance of white fur. The hands and feet are black.
