Unique Traits of the Hoolock Gibbons
Hoolock Gibbons are among the largest species of the Hoolock genus, second only to the siamang. They measure around 90 cm and weigh between 6 to 9 kg. Both males and females are similar in size, but their colouring is distinct: males are black with white eyebrows, while females are grey-brown. Their eyes and mouths are surrounded by rings, giving them an appearance akin to a mask.

Lifestyle and Natural Habitat
Gibbons are diurnal and arboreal creatures, meaning they are active during the day and live on trees. Hoolock Gibbons are known to form monogamous pairs and mark their territories. Their unique calls serve the dual purpose of locating family members and repelling challengers from their territory. Their diet primarily consists of fruits, insects and leaves.
The Hoolock Gibbons inhabit areas south of the Brahmaputra and north and east of the Dibang Rivers. Their range in India extends into the northeastern states of Assam, Manipur, Mizoram, Nagaland, Meghalaya, Arunachal Pradesh and Tripura.
Classification of Hoolock Gibbons
The classification of Hoolock Gibbons has seen several changes over the years. Initially, they were classified under the genus Hylobates, with the exception of the siamang.
A new subspecies of the Western Hoolock Gibbon, known as the Mishmi Hills Hoolock Gibbon (Hoolock hoolock mishmiensis), was recently discovered in northeastern India.
