| NAME OF ANIMAL | DESCRIPTION |
| SUMATRAN ORANGUTAN | SUMATRAN ORANGUTANS ARE LARGE, RED-HAIRED GREAT APES FOUND ONLY ON THE ISLAND OF SUMATRA. MALES HAVE PROMINENT CHEEK PADS, AND BOTH SEXES HAVE LONG, SPARSE ORANGE OR RED FUR. |
| MEASUREMENT | MALE | FEMALE |
| HEAD TO BODY LENGTH | 1.5M (4.92FT) | 1.2M (3.94FT) |
| HEIGHT | 1.7 M (5.6 FT) | 90 CM (3.0 FT) |
| WEIGHT | 130KG (286.6LBS) | 55KG (121LBS) |
| CHARACTERISTICS | DESCRIPTION |
| RANGE | THE SUMATRAN ORANGUTAN WAS DISTRIBUTED OVER THE ENTIRE ISLAND OF SUMATRA AND FURTHER SOUTH INTO JAVA. THE SPECIES’ RANGE IS NOW RESTRICTED TO THE NORTH OF THE ISLAND, WITH A MAJORITY IN THE PROVINCES OF NORTH SUMATRA AND ACEH. |
| HABITAT | THEY MAKE THEIR HOME IN LOWLAND, SUB TROPICAL BROADLEAF, RIPARIAN AND MONTANE FORESTS, MOUNTAINOUS AREAS ALONG WITH PEAT SWAMPS. |
| PRIMARY DIET | HERBIVORE |
| FOOD HABITATS | THE SUMATRAN ORANGUTAN PRIMARILY FEEDS ON FRUITS, MAKING UP ABOUT 60% OF THEIR DIET, BUT THEY ALSO CONSUME LEAVES, INSECTS, AND OTHER PLANT MATERIALS. |
| STATUS | CRITICALLY ENDANGERED |
| CONSERVATION STATUS | THERE ARE ONLY 7,500 SUMATRAN ORANGUTANS , REMAINING IN THE WILD. |
| REASON FOR THE STATUS | THE PRIMARY THREAT TO SUMATRAN ORANGUTANS IS THE RELENTLESS PACE OF DEFORESTATION ON THE ISLAND OF SUMATRA. AS HUMAN ACTIVITIES, INCLUDING LOGGING, PALM OIL PLANTATIONS, AND INFRASTRUCTURE DEVELOPMENT, CONTINUE TO EXPAND, THE LUSH RAINFORESTS THAT ONCE PROVIDED A HAVEN FOR ORANGUTANS ARE DISAPPEARING AT AN ALARMING RATE. |
| CHARACTERISTICS | DESCRIPTION: REPRODUCTION & BEHAVIOR |
| GESTATION PERIOD | 8- 81/2 MONTHS |
| YOUNG PER BIRTH | 1 |
| WEANING | 6-9 YEARS |
| LIFESTYLE | SUMATRAN ORANGUTANS ARE MOSTLY SOLITARY CREATURES, ONLY COMING TOGETHER FOR MATING PAIRS AND FEMALES WITH THEIR YOUNG. THEY TEND TO AVOID EACH OTHER, WITH MATURE MALES OFTEN ENGAGING IN AGGRESSION OR AVOIDING EACH OTHER ALTOGETHER. |
| SEXUAL MATURITY | 7-10 YEARS AGE |
| BEHAVIOR | THESE AMAZING CREATURES ARE DIURNAL, MEANING THEY’RE ACTIVE DURING THE DAY, AND BUILD NEW NESTS IN TREES EACH NIGHT TO SLEEP. THEY USE BENT BRANCHES, STICKS, AND LEAVES TO CONSTRUCT THEIR NESTS. YOUNG ORANGUTANS USE BRACHIATION EXTENSIVELY, WHILE OLDER, LARGER ORANGUTANS TEND TO USE HAND OVER HAND MOTION. SUMATRAN ORANGUTANS ARE MORE SOCIAL THAN BORNEAN ORANGUTANS, OFTEN SPENDING TIME IN SMALL GROUPS. |
| MAIN PREADATOR | SUMATRAN TIGERS, CLOUDED LEOPARDS, LARGE PYTHONS , CROCODILES, HUMANS |
| LIFESPAN IN THE WILD | IN THE WILD, FEMALE SUMATRAN ORANGUTANS TYPICALLY LIVE BETWEEN 44 TO 53 YEARS, WHILE MALES HAVE A LIFESPAN OF 47 TO 58 YEARS. |
| LIFESPAN IN CAPTIVITY | AROUND 50 YYEARS |
