1. (Common Noun-Neuter) The hoolock gibbons (Hoolock), is the only ape found in the Indian sub continent.This is primate species from the family of the gibbons (Hylobatidae).Hoolocks are the second largest of the gibbons, after the Siamang. They reach a size of 60 to 90 cm and weigh 6 to 9 kg. The genders are about the same size, but they differ considerably in coloration: males are black colored with remarkable white brows, while females have a grey-brown fur, which is darker at the chest and neck. White rings around the eyes and around the mouth give their face a mask-like appearance.The range of the hoolocks is the most northwestern of all the gibbons, extending from Assam in North-East India, to Myanmar. Small populations (in each case few hundred animals) live also in the eastern Bangladesh and in southwest China. Like the other gibbons, they are diurnal and arboreal, brachiating through the trees with their long arms. They live together in monogamous pairs, which stake out a territory. Their calls serve to locate family members and ward off other gibbons from their territory. Their diet consists mainly of fruits, insects and leaves. ভাৰতীয় উপমহাদেশত পোৱা একমাত্ৰ ’এপ’(গিবন জাতীয়) বা মানুহৰ ওচৰ সম্পৰ্কীয় বান্দৰগোত্ৰীয় প্ৰজাতি | এটা পূৰ্ণাঙ্গ হলৌ বান্দৰ ৬ - ৯ কিলোগ্ৰাম ওজনৰ আৰু ৬০-৯০ ছেমি ওখ হয় | মতা আৰু মাইকী হলৌ বান্দৰৰ দেহৰ বৰণ সামান্য পৃথক হয় | মতাবিলাকৰ ক`লা আৰু বগা পটী থাকে | মাইকীবিলাকৰ মুখৰ চাৰিওফালে নোমেৰে মুখা আকৃতিৰ অবয়ৱ গঠন কৰে | ইহঁতৰ প্ৰধান খাদ্য: ফল-মূল, গছৰ পাত, পোক আদি |
