Scientists unlock secret of proboscismonkey

KOTA KINABALU: There is a secret to Sabah’s iconic male proboscis monkeys – when they become bigger, so will their body and testicles.

But more importantly, the males with a bigger nose can attract more females.

According to a scientific study, there is a clear link between the nose sizes of the males and the number of females in their harems.

The study was jointly carried out by scientists from the Sabah Wildlife Department, Danau Girang Field Centre, Cardiff University and Kyoto University.

Researcher Dr Ikki Matsuda from Chubu University and Kyoto University in Japan said exaggerated male traits, such as a large nose, could be great for attracting females.

During this study, morphological measurements and behavioural observations in free-ranging proboscis monkeys were carried out in the Lower Kinabatangan Wildlife Sanctuary, Dr Ikki said in a statement.
