Hoolock – Hoo’ gibbons

Native to Bangladesh, NE India, Myanmar, and SW China

Hoolocks are the second-largest of the gibbons. They can reach a size of up to 90 cm (35 in) and weigh up to 9 kg (20 pounds). Both sexes are almost equal in size but differ noticeably in body coloration; females have grey-brown fur, while males are black-colored. White rings around their mouths and eyes give their faces a mask-like appearance.

These animals are primarily herbivores but can also consume small quantities of insects. Member species of this genus are particularly important from a conservational point of view. Major threats include habitat loss by deforestation and hunting for their meat used in folklore medicine.
