Gee's Golden Lutung

Fascinating facts about the Gee's Golden Lutung

• A golden leaf monkey in northeast India has a stomach the size of a small melon — divided into three chambers like a cow's, fermenting leaves for 12 hours before digestion even begins. This bizarre plumbing lets them survive on leaves so toxic that other primates would die from a single meal. They are one of only two primates in the world with this foregut fermenting system, a trait borrowed from leaf-eating antelope, not their fellow apes.
• Fewer than 2,500 Gee's golden lutings exist in the wild — fewer than the number of giant pandas — yet almost nobody has heard of them. They live only in a 60-square-kilometre pocket of rainforest in Assam, India, making them one of the world's most geographically confined primates. A single landslide, disease outbreak, or logging operation could erase them forever.
• Baby golden lutings are born bright orange, switching to gold and black as they grow — a colour change so dramatic that mothers sometimes reject their own newborns, thinking a different species has invaded the troop. Scientists believe the shocking infant colour may be a social signal that recruits the entire group to protect the baby, a theory still being tested in the field.
• They sleep 30 metres up in trees at night, huddled in groups of up to 10, but never in the same tree twice. Moving every evening spreads their weight across the canopy and leaves predators guessing. No predator has learned to hunt them successfully — their real threat is the saw that comes with the logging truck, not teeth or claws.
• A golden lutting's vocal repertoire includes a loud, honking alarm call that carries through dense jungle, but they also make a soft clicking sound inaudible to humans — a private conversation scientists are only now learning to decode using audio equipment. The clicks seem to coordinate group movement and establish social bonds, hinting that these monkeys have a richer social language than we ever suspected.
