The basal part of the thumb extends from the wrist rather than the palm of the hand, allowing an extended range of movement.

GEOGRAPHIC REGIONS AND DISTRIBUTIONS: found throughout borneo, exclude the southwest region (oriental region of the world); an island endemic.

They able to produce an offspring (one offspring) in 2 to 3 years time; with average 7 months of gestation period, and can breed throughout the year (no specific breeding season). They can reach maturity in 8 to 9 years. H. muelleri are monogamous.

LIFESPAN

Known to have a long lifespan reaches to 44 years in captivity and 25 years in wild.
