Javan Gibbon, also known as the Owa Jawa by locals. They are the great apes, have a human-like build and no tail. However, they are a bit different from great apes in that they have longer arms and dense hair. They also have a loud voice due to their throat sac, which they use for amplifying sound. Gibbons are arboreal and move from branch to branch with great speed and agility by swinging


Javan Gibbons inhabit the upper levels of the forest canopy in the tropical rainforests of Java. Deforestation and agriculture have destroyed much of their natural habitat, causing a decline in their population and putting them at risk of extinction.


Javan Gibbons have a slender build, with males typically weighing between 5-7 kg, and females weighing between 3-5 kg. They have long, powerful arms and legs, which they use for swinging through the trees with great agility. Javan Gibbons are monogamous and form strong bonds with their partners, engaging in grooming and other social behaviors. They are also known for their melodious songs, which they use to communicate with each other and mark their territory.

The lifespan of Javan Gibbons is estimated to be around 25-30 years in the wild. However, due to habitat loss and other threats, many individuals do not live to reach their full potential lifespan. Javan Gibbons reach sexual maturity at around 6-8 years old. Females typically give birth to a single offspring after a gestation period of around 7 months.

Javan Gibbons are primarily frugivores, meaning they eat fruit as their main source of food. They also consume leaves, flowers, and insects, playing an important role in seed dispersal and maintaining the health and diversity of their forest ecosystem.

Conservation efforts for the Javan Gibbon are ongoing, with a focus on protecting their habitat, preventing hunting and poaching, and raising awareness about the importance of preserving these primates. It is essential that we work to protect these amazing animals and ensure their survival for future generations to appreciate and enjoy.
