I see you!
Spectacled langurs have white patches around their eyes. Each eye has a thick circle around it, giving the appearance of eye glasses or “spectacles.” This species is also known as the dusky leaf monkey.
Graying with age
Spectactled langurs have a 145 day gestation period, and their newborns have bright orange fur! Groups of mothers have strong social bonds and nurse each others’ orange babies. After six months, the baby’s fur starts to gray. By ten months of age, young monkeys have turned dark gray or brown.
Eat all day
Spectacled langurs eat approximately four hours every day. That’s about four-and-a-half pounds (two kilograms) of food! Over half of their diet is leaves, but that doesn’t mean they don’t have variety. They eat from 87 different tree species. They also eat shoots, fruit, and seedlings from these trees. Some of these leaves are hard to digest. Luckily, spectacled langurs have multi-chambered stomachs and salivary glands that help break down the leaves better. Even though they eat so much, the leaves give them little energy, so they rest most of the day.
Large groups of five to twenty monkeys live together in the wild. Even if a group splits up, all monkeys will stay where they can see each other. They playfully interact by pulling tails, chasing, jumping, and wrestling.
Spectacled langurs are near threatened.
No effort is too small!
