[2], Black-and-white colobus have complex sleeping patterns. While some populations may breed throughout the year, others have a well-defined mating system, giving birth during the dry season, between December and May.

Intergroup Relationships in Western Black-and-White Colobus, Colobus polykomos polykomos. [10] However, more recent observations have shown variation in structure and the number of males within groups, with one species forming multi-male, multifemale groups in a multilevel society, and in some populations supergroups form exceeding 500 individuals. The females maintain close spatial relationships with one another and engage in grooming behavior. They are native to Ethiopia. Size: 45 - 72 cm (17.75 - 28.25 in); 5 - 14 kg (11 - 30.75 lb).

In addition to being fast, king cobras can raise more than one-third of their body off the ground to warn off predators. As such, they primarily live in trees, but often forage on the ground too. This allows them to use bacterial fermentation to break down their food, which is typically low in nutritional value and eaten in large quantities. They are closely related to the red colobus monkeys of genus Piliocolobus. Gestation period lasts for 175 days, after which females give birth to a single infant, usually once every 2 years.
